I have just completed my 1st 1/2 marathon, in fact my first race of any sort, and to be honest I'm feeling pretty pleased with myself.
But.... I really suffered with my legs in the last 3 miles, they stiffened up and I felt like my calfs would cramp up if I tried to accelerate, quite a few ran past me in the last mile!
I only drank water during the race and have never used gels or anything in training, anyone had the same experience and got round it?
