I have a cramping problem with endurance events such as hiking or bicycling. After about 3 hours of continual pedaling or climbing a mountain, my hams and especially quads just start knotting up!
It hurts like hell and I can’t figure out what I’m not doing right. On every occasion it happened to me, I drank large amounts of gatorade and water. They have even happened to me when I was eating bananas as fuel during a long event.
I am guessing that it can only be attributed to two possble things.
Since I train heavy for legs, my rep range is never high enough to build the endurance qualities in my quads and therefore they cramp.
On almost every occasion, I was short on sleep (and used caffiene).
I know it’s not a lack of warming up, because it almost always happens after 3 hours.
Any thoughts would be appreciated.
