I had done 10 laps, really pushing myself, and was deciding if I should break next time round or the time after that, when I started to notice a pain at the tops of my legs, just below my butt cheeks. I get this on rides sometimes, but normally 2+ hours in, not about 70 mins. I realised that I had hardly been out of the saddle, and maybe had been too fixed in a low aero position, either on the drops or down low on the stem, a bit like an improvised TT position. Maybe I had also been pushing too hard, certainly it was the hardest I have ridden continuously, although at that point I was still able to lap consistently. Within half a lap, it was excruciating, and I knew I would have to stop at the end of the current lap.
Pulled in to the pits, and getting my leg over the top tube was murder. I couldn't squat, I couldn't even sit in a chair. Eventually I sagged on to the grass and lay on my front, then rolled over and started bending my knees, pulling my feet up to my bum and pushing out gently. Walking also helped. For a time, I thought I would be going home in an ambulance I was that concerned.
I did get back on the bike about 15 mins later and managed 5 or 6 laps but they called time, so had to stop. It still hurts now, 5 hours later, although not as much. Two days later it has almost gone but not quite.
So is this cramp or something else? I have had cramps in my calves feet before, but that feels a bit different, and hasn't happened on the bike or after a ride. As I say, I do get the pain to an extent after 2 hours, but moving on the saddle or coming out of it makes it go away. Today, getting out the saddle helped, but not completely.
I have had the shorts for several hundred miles, but I think maybe I wasn't sitting on the padded parts. I rode the bike over 5,000 miles last year and nothing about the position of the bars/saddle/stem has changed.
What really worries me if this happens on Ridelondon, or worse out on a solo ride 50+ miles from home, I will be well and truly up the creek.
