I'm just getting into sprinting and have done 2 sets of efforts.
On the first set, I was using a 106" gear (on the advice of a friend) which was way too high. By the time I was going for the actual effort, my legs were popped. Added to that, my line was all off. Appreciated that a F200 is much more of a technical event than first thought. Fastest time on this session was 14.997
Second session, I had a teammate show me the proper lines and give me a couple of tips. Dropped my gearing to 99.7 and it made such a difference. Fastest time was 13.548 (and second fastest was 13.549!) so ~1.5 secs quicker. Did also try a 91" but that was a bit slower (wind up was easier, but just couldn't hit that top end)
Next goal is under 12. I have some Deda Pista bars on order, which will replace the bog standard road style bars, and some toe straps
