leg cramps in high intensity intervals

I am getting quad cramps toward the end of interval workouts. I don't seem to get them as much in distance work. One of my favorite workouts is 25 x 66 yds on 2 minutes. The first ten are usually 50 sec and then I slow to 55. I start cramping on the 20th rep. It happens on push off when the quads want to lock up and also the calfs a bit less. It ends up ending my workout. I notice that if I extend the rest interval longer (because I am talking to someone....or just plain stalling), it brings on the cramping earlier and worse. Is a minute rest a no no? Should I lessen the intensity and reduce rest for this workout? Yes I eat bannanas and drink plenty. Why the legs and not the upper body muscles?? When I used to run intervals sometimes I would get chest cramping of all the places, but never the legs!! how ironic.

    It could just be muscle overexertion, seeing how you are taking care of things like hydration and potassium. You could try backing off the intensity just a bit and see if that makes a difference. I sometimes get cramps in the chest when I am swimming a hard set and I generally just accept that it is the price I pay for working hard. A relaxed 50 usually quells the pain and I return to my previous plan. Quick and easy cure.
