Calf Cramps

A few weeks ago I was Calf cramping - I upped my water and have been eating a banana each morning and have not had any more since then.

They'll go away as you get used to this. Mine were horrible for the first two/three races but as I put in the miles the calf cramps went away. The quads now cramp after 3 hours on the bike then running a 10K, mind you, but I'll bet those will go away after a while when I get more used to those distances as well.

Depends on fitness, hydration and weather.
Stay hydrated and get in your training!

Over the winter and beginning of my season "2009" i have been hard as hell on the swimming and biking. And now, after doing two tri's i am training my running harder then ever.

Yaaaa... i got calf cramps and shin pain on a long uphill session, it lasted throughout my next two runs.... but personally I'm thinking it is because of the "tempo" shoes i have been using. I just ran today im zoot TT 2.0's instead of the Tempo 2.0's ,..... and there is a difference, but i am definately looking into some Asics Gel Kayano for my non-race runs.
Wait a couple more runs untill your leg below the knee strengthens a little.... but if it continues look into some proper shoes.   Maybe somehting to do with the archs in your foot.

Question, do you mean training run or in a race transitioning from bike to run?

For training +1 on banana's, hydration, and more training.  For races, practice bricks, use gels, pick up your cadence during the last mile of the ride (drop to a lower gear to make this easier).

How old are you? Any medical problems? Do your calves cramp during any other type of exercise?
