I just completed a bike ride with one of the local chapters of Audax Club Parisien.
200km, plus another 70 for the round trip to and from the base point. That’s the furthest I’ve ever ridden in one day by about 100km.
My main goal was simply to finish (Most Audax rides insist on a minimum 15kph average speed, so the time limit was 13 hours, 30 minutes). My secondary goal was to do it in under 10 hours. That wasn’t based on any realistic first-hand experience with the course, just on the results from previous years. I managed to finish in 10 hours, 37 minutes, which I’m happy about.
My knees are still killing me, my shoulders are aching, and I’m only just starting to get the feeling back in my crotch. If I do this again, I need a new saddle.
