For my 24hr record attempt, I spent considerable time searching for a suitable venue. The Basin Reserve Cricket Ground which I used for my 2005 record has a fantastic 465m circular track, but is much busier these days, both with weekend events and general traffic. I was given one option in early November with no backup for inclement weather, so it was risky proposition.

The ideal venue would be flat, at least 400m in diameter, with no hard corners/turns. I contacted the Newtown athletic stadium, but they do not allow cycling on their running track. There is a concrete path around the athletic field, but with a couple of right angle turns it isn’t really suitable. Then I visited the Hataitai velodrome after seeing photos of their refurbished track. The steep banking was out of the question (I knew this from 2005), but there is a flat concrete track on the infield. Well, it looked good in the pictures. Turns out there are a whole lot of wooden planks across the track- not ideal to change riding surface every few meters. The 333m velodrome is also a bit small to be circling for 24hrs. I looked further afield to Lower Hutt, Upper Hutt and even Masterton. The further I went, the harder it would be to organise support crew and logistics.

I had pretty much settled on the Basin Reserve until I went for a run and came across a concrete track at my old school, Newlands Intermediate. I walked past this field every school day as an 11/12yr old, but it was a looooonng time ago. They have built a 400m concrete track around the bottom field since, and it was a gem of find! The track is smooth, has little traffic, and seemed pretty fast. I was so excited I contacted the principal the next day, who was very happy to help. They’ve been very supportive, and will allow me access to the track and school hall for the attempt. A group of Newlands Intermediate students also came and interviewed me for their newsletter.

One cannot attempt a Guinness and IUF world record without making sure the track is measured accurately. I contacted Cuttriss, a surveying/engineering/planning company, who were involved in measuring the Basin Reserve which I used for my 2005 record. They sent a couple of surveyors, Brett and Ollie, to help me measure the track. I can’t thank you guys enough!

The track came out slightly shorter than expected, at 390.76m on the inner circumference. Not the worst outcome, but does mean a few extra laps to hit my goal.

It must be the worst kept secret, but many of you will know that I am having another go at the 24 Hour Unicycle Distance World Record. I set the world record on Feb 5th/6th 2005, riding 378.7km in a 24hr period. It was one of the toughest things I’d ever done, and probably something I never thought I’d do again. Well, fast forward almost 20yrs and I’m itching to have another crack.

My record stood for 2 1/2yrs, before Sam Wakeling (UK) smashed it with an incredible 453.8km ride in 2007. It was an amazing feat considering the technology of the time. Enough to put many off the pain and process of attempting the world record.

So what’s changed? The body is 20yrs older, but I’m going faster than ever. At Unicon, our world championships, I came 2nd in the 54km road race and 2nd in the 10km road race. That was for the overall, not my age group. Although I did not ride standard class in 2006, my times are equivalent or better than the year I was the road racing world champion.

The other major change is the technology. While geared hubs have been on the scene for a while now, I never felt they were suited for a long distance challenge. They are good for going fast for a short distance, but I don’t have the power to keep that pace for 24 hours. I will be using a standard ungeared 36″ unicycle, but the wheel is now 2kg (that’s right!) lighter than the wheel I used for my 2005 world record. Where the Coker Airfoil rim and TA tyre was the standard in 2005, now we’re on carbon rims with tyres that are 800g lighter, inflated with TPU tubes that weigh a fraction of butyl inners.

Add in 20yrs of experience pushing my body to the limit, some better handlebars and a comfortable seat, and I think I’m ready for the challenge!

I will be attempting the world record on the 16th/17th November 2024, 0800hrs-0800hrs, at Newlands Intermediate School, Wellington, New Zealand. Keep an eye on the 24hr Record Page for updates.

These days I spend most of my time riding, touring and racing on 29″ unicycles, but I was super excited when I heard about the new 36″ Braus carbon rim back in 2020. It was less than half the weight of the various aluminium 36″ rims, which is a hefty saving considering the weight of these things!  I had the idea of using this wheel for the Lake Taupo Cycle Challenge, a race I do every year.  My old best time of 7hrs 43min was set on a much heavier 36″ unicycle in 2004, so this was my best chance of breaking the record.  I was also eyeing up Tour Aotearoa, a 3000km ride of the length of NZ.  

The Braus rim weighs in at 546g (claimed), compared with my original Coker Airfoil rim (1232g*).  Another exciting development in the diet stakes was the Nimbus Nightrider Lite tyre, with a claimed weight of 1310g,  compared with the original Nightrider tyre weighing in at 1960g* and my wheel TA tyre 2060g*.  Add to this the spoke count of 32H instead of 36H, shorter and lighter Quax cranks and a set of Ti AEST pedals, and I’d saved over 2kg in rotating weight, and almost 1.5kg of that was in outer wheel diameter where it matters the most.

Then Covid happened, and the annual Lake Taupo Cycle Challenge was postponed not once, but twice, meaning that I couldn’t test it in a race where I have almost 20yrs worth of history.  

In 2022, I decided to ride Tour Aotearoa, and this would be the ideal unicycle except for one thing- the tyre is a very tight fit, so isn’t the easiest thing to fix in the event of a puncture.  The rim is drilled for presta valves. and is too narrow to drill for a schrader valve, meaning I had to use a 29″ inner tube stretched to fit, instead of a 36″ tube.  It’s another weight saving, but I pinch flatted two tubes on installation, so was not the best setup if I were to have a puncture on tour.

All this meant the unicycle sat in storage for over 3 years until I came across the 36″ TPU inner tubes by Trentasei.  It has a presta valve (great!) and is made for a 36″ diameter wheel instead of being stretched from a 29″.  I ordered a couple of tubes from Luca at Trentasei36 in Italy.  He was super helpful and the tubes arrived quickly.  Having had bad experiences with ultra light latex inner tubes many years ago, I was sceptical of TPU inner tubes.  The 36″ TPU tube weighed in at 103-108g, another big saving compared with a 29″ CST butyl inner tube (260g), and a 36″ butyl inner tube (524g).  Better still, without the excess stretch of 29″ tube, I installed it easily without damaging the tube. The material, although very light, doesn’t have the balloon like feel of a latex tube. It holds air well (unlike latex), and makes a nice springy, hollow sound when revved up to speed. It not only feels fast, it sounds fast!  As a bonus, the tube rolls up into a small compact bundle, which makes it easy to carry a spare. This has to be the best value upgrade for a 36″ unicycle. 

As for the Nimbus nightrider lite tyre, it performs as well as its heavier predecessor, with a grippy tread that handles road camber well. There is plenty of volume, so it’s a comfortable ride. Perhaps a narrower road tyre in future could save even more weight, but it’s easily the best 36″ road tyre currently on the market.

I took the unicycle on a ride through my hilly neighborhood- including a 10-15% gradient climb to my house.  It felt snappy, maneuverable, and accelerated and decelerated like a 29″ unicycle, except I was going at 36″ speed!  I fitted 100mm cranks, where I would normally ride 125s on the same gradient.  It had a similar feel to 29″/89mm.

The best demonstration of the whole system is to race it, and I smashed my 2004 Lake Taupo Cycle Challenge record by 15min!

Lake Taupo Cycle Challenge has been a regular event on my calendar since my first ride exactly 20yrs ago, in 2003.  It is New Zealand’s largest cycling event, which started in 1977 with a handful of riders, and built to a peak of over 10,000 participants in the late 2000s.  This year was extra special. The 2020 and 2021 events had been cancelled because of Covid 19. Up until then, I had only missed one challenge, followed by the cancelled events, then also missing the 2022 challenge for my medical school reunion.  This would be my first LTCC in 4yrs!  

It was also extra special to have my family come and support me.  Gryffin was just a baby when I last rode in 2019. Now we bundled 5yr old Gryffin and 2yr old Anthea into our van, along with my new 36″ unicycle and their scooters, and drove up from Wellington the day before.

There’s always a great atmosphere when you arrive in Taupo. The town is buzzing with cyclists and the event hall is full of sponsors and bike industry folk, showing off the latest and greatest. The best thing was getting free samples from sponsors Harraways (it helps to have cute kids), who make my favourite pre-ride breakfast Apple and Cinnamon oats!

Registration was quick and easy- the event is rebuilding after the 2021 and 2022 cancellations, so queues were short. They’ve done away with plastic goody bags which I guess is a good thing for the environment.  

After fueling up on kebabs, it was back to the motel for a last minute equipment check.  Having done 15+ challenges, it was pretty cool to pin on my silver number plate. This would be my 17th ride, the 15th on a unicycle, and 19th lap (I’ve done the 2 lap enduro twice on my bike).    You have to do 20+ for a gold number plate, so I’m almost there.

I went back to basics this year- a 36″ ungeared unicycle.  In past years I’ve ridden everything from an ungeared 36″, to a 24/125mm standard, to 29″ geared, 36″ geared, 29″/89mm and 700c/75mm.   The course is a shade under 160km, and has 1700m of climbing, so the unicycle has to handle the big hills, long flat straights, some vicious camber, and whatever the weather throws at you.   My fastest time was set in 2004, at 7hrs43min, on a 36″ unicycle with 110mm cranks.  The closest I’d come was on a 36″/145mm geared unicycle at 7hrs48min in 2011.  While gears are great for extra speed on the flat, the extra momentum is tricky to control on downhills, especially for a lightweight like me!

After spending much of the last 19yrs trying to break my 2004 record, I had resigned to the fact that my legs were exceptional that year, and I probably don’t generate as much power on as I did in my 20s. 

That was before I took a test ride on my new carbon unicycle. The wheel is 2.5kg lighter than my 2004 setup, and 2kg of that is in the wheel/rim/tyre where it counts the most, with the remainder in the pedal and cranks.  The new setup consisted of a carbon Braus rim/36″ Pollici TPU tube/Nightrider lite tyre matched to Quax 100mm cranks and AEST Ti pedals, instead of my old Airfoil rim/36″ butyl tube/TA tyre with steel Bicycle Euro 110mm cranks and the original Snafu pedals.

 It felt like riding a 29″ unicycle at 36er speed- I could climb with 100mm cranks where I would normally need 125s!   The equivalent of two crank-length increases in speed without extra effort.  Still, being 4yrs since my last challenge, it was a risk to go with 100mm cranks- something I would never have dreamt of using in 2004.

The other upgrades were the NNC flatfish seat and KH T-bar at full extension. It had taken me over 20yrs of distance unicycling to realise the comforts of a long extension bar, as I discovered during last year’s Tour Aotearoa. It meant less saddle pain and wasted time on crotch adjustment stops.  All this was bolted onto a solid but lightweight Triton titanium 36″ frame. I decided against using brakes- there are only one or two sections where a brake would be helpful. 

So, it was looking good, until the morning of the race, when our van wouldn’t start!  Our motel is16km from the start, so I was going to miss the 6.20am Group 9 start!  Thankfully, a nice chap who worked at the power station stopped to give me a lift as I tried to hitchhike to Taupo.   It turns out that our van key has an electronic chip which stopped working when I duct taped it together the day before!  My wife Anna got it working, but not in time to get to the start before I headed off. 

Being in the ‘slow’ group, it was great to be the first start of the day, 40min before the regular groups. It means getting to the finish without being the last riders in, and also much cooler weather. I can’t recall nicer conditions in many years- it was overcast, with temperatures in the teens. Just right.  The legs felt good and by the top of the first climb I was ahead of all the Group 9 riders. We played yoyo for a number of kms, with them flashing past on the downhills before I passed them again on the climb.  Just like the old days!

My trusty garmin was reading an average speed over 23-24km/hr, which was great on the first hilly section of the course.  The 100mm cranks were effortless on climbs, and super fast on the descents.  Better still, the nightrider tyre handled camber extremely well, so I could rest on the downhills instead of wrestling with the unicycle. By the time I hit the 40km mark, I was under target time, and I was hopeful of setting a new record.   I had a quick stop at the 70km drink station, but with a mistimed dismount ended up dropping my unicycle.  The long handle was pushed down slightly, giving me an uncomfortable angle.  The question was whether to fix this or get used to it!  I elected to do the latter, but it took a while to readjust.

On the Kuratau climb after the halfway mark, my legs were still in good shape, and I went up just fast enough to stay on without burning excess energy.  The descent was fun, but perhaps not as fast as I’d done in 2004 because the crosswind kept steering me off the road. I had my only UPD, when I was caught by a wind gust. Luckily no damage was done and I took it slow until the bottom.  By then, my average speed had dropped to just over 20km/hr. I had to make up time on the flat straight to Turangi, right into a headwind!  Unicycles are about as aerodynamic as a flying brick wall, but we make good windbreaks.  Despite many groups going past and giving me encouragement, there were few riders to draft.  

Heading around the Lake was fun- and there was just one last hill to go!  Hatepe isn’t particularly steep, but it is relatively long and comes late in the race.  I was determined to ride all the way up, so kept spinning gently to keep my legs going into the red.  Like previous years, I passed a lot of riders who weren’t expecting to see a big unicycle go past!

Once over Hatepe and it was onto the home straight, the legs were still good but I was unsure whether I was on track for the record. My garmin flashed a big ‘Low Batt’ note over the screen, obscuring my elapsed time, so it was anyone’s guess.  I decided that I had slipped behind record pace, so I just enjoyed the ride into Taupo.  While I don’t mind a bit of headwind, as I made the final turn into Taupo I was hit by a crosswind.  It was a little embarrassing as I flailed around like someone trying to learn to ride a unicycle.  The wind died off as the road went through the built up area, and then finally I was in the finish chute!  Better still, after stopping my garmin, I’d taken 15min of the old record, coming in at 7hrs28min!   Woohoo!

Anna and the kids unfortunately missed my finish- they weren’t expecting me to come in so early.  Ice cream for the kids and a tired unicyclist was the perfect way to end the day. 

The first thing I discovered about Tour Aotearoa is that the more stuff you carry, the harder it is. I ended up dropping a lot of excess gear (thanks to Mike Holland and Bryan Page, for posting them back to me!)

Total unicycle weight: 5.1kg

Total pack weight (without food/water): 8.6kg 5.1kg

Dropping 3.5kg made a huge difference to my long distance comfort- I was no longer getting sore shoulders, and I could last much longer in the saddle. I carried up to 2 x 750mL water in the pack, and a 750mL water bottle on the unicycle. On days with minimal water/ food stops (eg Big River trail, Queenstown to Mossburn), I carried 2x 1.5L water in my pack, and up to 500g food. In the first few days of riding, I drank far more than I could carry, but as we went further south, the weather became cooler and I ended up with excess water.

I was able to wash my riding clothes most days, which would dry overnight, so there is little need to have 3 cycle jerseys and 2 cycling shorts! I kept a second pair of socks, but it wasn’t necessary. It’s important to have non-riding ‘civilian’ clothes if you want a meal at the pub with clothes on, so I kept a pair of trousers and my Tour Aotearoa t-shirt. The pack towel is nice, but if you are staying in motels/hotels one is usually provided. Even when it isn’t, shaking yourself dry in 5min is preferable to carrying an extra 100g over 3000km.

I used the bivvy/sleeping bag on a couple of occasions, but my goal was to complete the TA under brevet rules, which is under 30 days. Some riders aim to be as self sufficient as possible, but I had to compromise on camping. In order to ride 100km+/day, it is important to have a good sleep/rest, so I stayed mainly in hotels/motels/B&B. The bivvy/sleeping bag was insurance- there were times where I considered sleeping on the side of the road because I didn’t think I would reach my accommodation. It could easily happen with mechanical issues, injury, or underestimating the time/difficulty of a particular section.

My primary navigation device was my Samsung A52 phone, running on the Vodafone network, which I also used to write this blog with! There are many areas in NZ with poor cellphone reception. Some riders have found the Spark cell network more extensive, so it may be worth having dual sim cards for the trip.

My android GPS app was Osmand, which has excellent offline capability. I had trouble getting it to follow the TA GPS track (it would make its’ own preferred cycle route), but it was otherwise easy to navigate- just make the blue dot follow the red line. If only high school orienteering had been this simple!

The Kennett Bros TA guidebooks are invaluable, but I ditched the books for the PDF version to save extra weight. It gives you navigation advice as well as tips like where food/water stops are. For speed/distance, I used an 8yr old Garmin Edge 200 cycle computer, which runs on GPS but has no navigation capability. With the combination of Osmand, TA guidebooks and cycle computer, my only navigation error was on Day 2, where I missed my accommodation by 2.5km because I cycled past it in the dark.

I used a 20,000mAmp/hr powerbank, but could have gotten by with 10,000mAmp/hr unless camping. My helmet mounted headlight worked poorly on gravel- the best place for a light is on on your handlebars because it casts a shadow over rocks/corrugations, giving you depth perception. A light above your head makes everything look 2 dimensional. I sent the more powerful bar mounted light home to save weight, but then picked up another when I reached Wellington. By then, my routine was pretty well sorted, so I didn’t end up riding much in the dark. For rear lighting- the 270 lumen Knog Cobbler has 330 degree cover and can be seen easily during the day. I turned it on for all busy roads/state highways. The other item I’m very pleased with is the Oxford bag cover. It is marginally small for my 35L pack, but has great visibility both day and night.

The 29″ Triton unicycle performed well, although swapping to a longer KH handlebar (after the North Island) helped spread the load and improved long distance comfort. The water bottle mount was helpful- it reduced the amount of water carried in my pack, and could be accessed while riding. I replaced my bearings at the end of the North Island, but should have started the ride with fresh bearings. The Triton titanium frame was flawless, and the only thing I didn’t have to worry about. My Vittoria Mezcal III tyre rolled well both on and off-road, with no punctures, but it may be worth going tubeless with sealant to reduce puncture risk further. The Nimbus VCX triple hole cranks (100/125/150) was lighter than carrying spare cranks/extractor but I only used 100mm for on-road and 125mm for off-road. On a 29″ ungeared unicycle, it would be good to have an 89mm option for flat riding, but there are no triple hole cranks with 89mm. The entire rig was very light (5.1kg without water), climbed well and handled off-road sections with little difficulty. I could attach equipment/bags to the unicycle, but would not want more than 2-3kg. There are tricky sections which cannot be fun on a fully laden unicycle…consider TA to be more a unipacking trip than a unitour.

We spent a couple of days in Bluff and Invercargill, just sightseeing without pedaling! We took Gryffin, my 3yr old to the transport museum, which is a pretty awesome place for a boy who loves trucks and diggers! Then it was off to visit the Lost Gypsy Gallery in the Catlins, featuring a whole lot of amazing automatons.

To complete my NZ journey, I needed to ride on Stewart Island. It’s one of those places you never go and always wonder what’s there! We flew from Invercargill to the Stewart Island in a 9 seater plane, landing on an airfield above the town of Oban. Most of the island is uninhabited, except for this settlement.

There is some great fishing there, and Anna caught enough to feed us for the entire trip! We took a walk on Ulva Island, seeing plenty of penguins, sea lions, albatross and other birdlife.

Anna hired a bike and trailer and we cycled around the town (there is only 20km of road in Stewart Island, so we saw most of it)!

Final day! After almost a month riding it is hard to imagine that my routine of eat, ride, sleep, and living out of a backpack would soon be over. 
I left the Mossburn Railway Hotel just before daybreak. It would be a long  ride of about 138km, but most of it flat/ gently descending. My wife Anna and kids Gryffin and Anthea would be flying to  Invercargill and driving down to Bluff to meet me, so I had extra incentive to get there. 
It was a very pleasant ride, with most of it on road.  The weather was overcast with occasional light rain, but not enough to get out the wet weather gear. 

I was making good time, generally cruising at 17-20km/hr, but felt dreadfully undergeared. If there is a reason to carry 89mm cranks and a crank puller, this is it (perhaps also on the Wairarapa section).  My biggest tip for long distance unicyclists is to use the shortest cranks you can get away with. A unicycle is geared 1:1, so has very low pedaling resistance. Shorter cranks reduce leverage and provides ‘lift’ when you push down, reducing pressure on the seat. This makes a huge difference to how many hours you can last in the saddle. 

There were no towns for 70km, but with the speed and weather, I could manage without carrying excess water or food until we got to Winton. As we arrived, there was Police Officer filming from the side of the road- don’t think I’m breaking any speed limits. 

Turns out Officer Reuben from Winton Police was a TA rider in 2020, and gave a police escort to several TA riders heading into town. How cool is that!  

After lunch I was back on the road, aiming to arrive by 5pm. I had a second lunch in Wallacetown at 93km, then set off on the final 40+km. 

I almost ran over a very large box in the middle of the road as I approached Invercargill, so I got off to kick it to the side. It was filled with marijuana leaves. How weird. 

There was a big crosswind as I entered Invercargill cycle trail alongside the estuary. This will be tough few k’s!  I was flailing about like a beginner unicyclist trying to go in a straight line. Luckily only a few locals saw my wobbly act. It eventually turned into a headwind, which is preferable. 

20km to go…10km… I was counting down but also taking my time to savour the end of TA. 
2km…just round the corner. I stopped by the side of road to pick flowers for Anna just as some TA riders went past and caught me stealing someone’s geraniums. Oops. 

1km…500m…50m….I saw Anna, Gryffin and Anthea waving at me and stopped.
It’s not the finish! They didn’t realise it was at the sign. 

20m to go…I rode up the the sign…finished!  3000km in 27 days 11 hours. 

Most of the TA riders from today were still there along with TA supporters, so it was great having people to celebrate with. 

Final checkpoint photo…done. Spot tracker…off. 
That was quite an adventure.  We’re spending a couple of days in Bluff/Invercargill before flying to Stewart Island for a holiday. 

I’ll do a final summary on the blog and add photos in  week or so. In the meantime, you can see the photo highlights on the Adventure Unicyclist Facebook page. 

I would like to thank the Kennett Brothers for coming up with the concept and route for the TA, and to Shane at Map Progress for running the event and providing tracking. Thanks to all the riders/supporters who helped me along the way, whether it was sharing water/food/accommodation when I’d misjudged, your encouragement, or your stories/humour. I’m grateful to all the great businesses, making sure we were fed, watered and housed along the way.  

Most of all, thanks to my wife Anna for putting up with my crazy pursuits and solo parenting for month. I couldn’t have done it without you!
