Yesterday I rode 48.5 miles. It was 18 miles longer than what I have ridden since early last fall. I felt pretty good until mile 37 when my thighs started cramping and I felt like I had the beginning of a charlie horse in the tear-drop muscle of my left quad.
I had been sipping on water and Hammer Sustained Energy (started about 45 minutes into the ride) and at the half-way mark I stopped for a quick break, refilled a water bottle and ate a bread roll.
Is it possible the bread roll slowed absorption of the Sustained Energy and that is what caused the cramping to start about ten miles later?
It was weird. I've "hit the wall" before and that felt like my legs wouldn't work or as if they were really heavy and my speed dropped significantly. Yesterday my second half was riden at the same pace as the first half and aside from the muscle cramping I felt like I had energy to spare. But it really hurt so I didn't push to get all the way to 50 (would have had to go out of my way but it was only 1.5 miles!!).
Today I am a little sore/stiff but I've definitely been more sore from running.
Any ideas on what caused the weird cramping? I'd like to avoid it in the future if I can!
(It was still an awesome ride.)
