I did it. It was brilliant, I really enjoyed it. My 20minute power was probably around 320+ watts at 64kg, my Everesting hills (x 100), each climb was about 7:10 at 200+ watts. I was like a metronome so either judged it well or didn’t push hard enough…! Had a straight easy descent so no need to brake, could stand up and freewheel and stretch it out. Was pretty much unsupported so had to carry a fair bit of weight. Had a friend rode a few hours with me but what would have been better “support” in terms of making you faster would be having someone permanently at your “base camp” to take your orders! It took way longer than I originally thought. 16+hours with 90mins off the bike over the day re-stocking, toileting etc. But I didn’t race it, I did it to complete. If I’d had more daylight I would have loved to have continued. I got to 9600m or so before I decided it was too dark and dangerous - bats and animals everywhere. The hardest part was actually getting myself there and getting on the road. I had two failed attempts where I couldn’t sleep (at all) and called it off because I didn’t want to do such a long ride without sleeping. On the third attempt I still hadn’t slept but was fed up with it all, building up mentally and getting everything ready and wanted to just get out there and try it. A litre of flat coke after a sleepy first couple of hours and I was fine. The flat coke was good throughout! I never have trouble sleeping but maybe I felt it was a big unknown, hadn’t trained specifically for it, had never spent that long on a bike before, it was a bit exciting and a bit daunting, also I did feel a bit vulnerable alone out there and my car and I were fairly conspicuous, so maybe that was playing on my mind too. If I could go back with hindsight, I’d have just gone and done it at the first opportunity. I’d do it again, but not this year - not enough daylight any more! I’m in the process of writing a blog post about it but let me know if you’ve any questions! I’m no expert but I’ll answer what I can…
