Other interesting facts

  • Jesse has never owned road shoes / pedals before this race. His first ride on road pedals was only three weeks out while trying to break in a pair of Rapha Climbers shoes using borrowed pedals.
  • Not one flat tyre for 7,000kms - Thanks Continental.
  • One hiccup occurred early on just before the race. In the final rush before departure, the small chain-ring was installed backwards, affecting shifting. A last minute check-over from the guys at River City Cycles in Portland Oregon spotted the problem and they rectified it just in time.
  • Custom elbow pads were made out of closed-cell foam pads and velcro. These were shaped using woodworking tools from my home workshop.
  • Jesse is very particular with cleat positioning. The stock hole drillings on the soles of the Rapha Climbers shoes do not allow the cleats to be moved far enough back for Jesse's preferred position. After a quick consultation with Raoul Luescher of LuescherTeknik regarding carbon sole modification, then a bit of trial and error in house, Jesse called upon engineer friend Carl Maroney to fabricate some cleat hole plate adjusters from 3mm Titanium plate. As with all of Carl's work, the adapters worked perfectly

    Hi Rod,
    I think the bike weighed about 8kg without bags, food or bottles (but with aerobars, cages, pedals and mounts).
    The guys at Newton Bike Shop said it was about 28lb (12.7kg) all packed and loaded. That excluded bottles, I think, but would have included a few hundred grams of food.


    What did the bike weigh – with and without the gear bags?


    Hi Dave,
    I’ve used the eTrex 30 for a number of years now. I like that it runs from easily replaceable AA batteries (or from an external power source via a dynamo hub), doesn’t use a touch screen and is a lot more robust than the cycling specific Garmin models (well, everything to come out since the Edge 705 which was amazingly reliable). It has some nice functions compared with the eTrex 10 and 20. I like the elevation profile function – you can set up your map so that the top portion of the screen shows the upcoming elevation profile on the track that you’re following. Very handy when you want to see how much longer the pain is going to last on a climb!


    Hi Curvers, why did Jesse choose to use the Garmin E-Trex 30?

    Hi UpDave,

    Thanks for the queries!

    The position on the bike was built around the aero bars. I like a pretty forward position as it is. With the bars I chose (which had integrated aero extensions) I needed a 100mm stem to get the right position on the aero bars. This meant that I had a pretty upright position when on the hoods, which was fine for touring. The stem would’ve been different had I used conventional bars that could have been independently adjusted – this would’ve been sensible but I opted for a much lighter solution.

    The cage on the seat post was a stretched Arundel bidon cage attached to the post with seatpost collars which had threaded M5 holes. I got these from Fitzroy Revolution. They had a few of them in stock from when their riders took on the Crocodile Trophy and Tour of Mongolia and needed extra bottle cage attachment points. I made sure the lower clamping point was in the clamping zone of the super light post. The upper mount was lightly bolted on the thinner carbon. The dry bag was strapped to the post with cheap velcro straps.

    To be honest the jersey didn’t smell all that bad at the finish. My Mrs and Steve (at Curve) can vouch for this. I know everyone says this about themselves, but I’m not a terribly smelly person. If you take care of the basics of personal hygiene in bathrooms along the way the smell really isn’t too bad. Merino really is magic stuff, the anti-smell qualities of the fabric is not just marketing crap, it’s real. The surprising thing is that even with merino blends with only 30 – 40% merino, the anti-smell property can still be maintained.

    Regarding recovery – I think it’s the toughest part of the whole process. I had some sickness along the way which meant I started burning through muscle pretty early. This means you finish these things incredibly fit / efficient but very weak. It’ll take a while to regain my strength and while that’s happening the fitness will fade. About a week and a half after the race I had my first sleep longer than 4 hours and only now am I getting into the sore and lethargic phase. Mentally it’s pretty tough too – endorphins are charging through your body for a couple of weeks and suddenly it stops. I imagine it’s kind of like a drug comedown too! You really need to let yourself off the hook for a while after these things – I think that helps with the mental aspect of recovery.
