Let's talk about calf cramping
So yesterday I set out on a ride, 50 miles total, 7-8 miles warm up then 5 miles of solid climbing ~1100ft in 5 miles.
At the top of the climb and just riding rollers my left calf starts cramping so bad I could see it, worst it's ever been.
I am susceptible to left calf cramps but not this bad, I had to stop and stretch it out, then nurse the rest of the ride (35-ish miles)
I ate two endurolyte pills before the ride plus a chewable Hammer Perpetuum pill and drank most of a bottle of HEED.
Admittedly I haven't been riding that much but what in your opinion caused such a big muscle cramp?
