severity grade: 3
During NAOL long race got cramps at left calf and hamstring areas that progressed through the race to the point that barely finished. Stretching and massaging at the beginning after second control didn't help much.
At our age we should be more careful about running, running fast, and running viciously :) Seriosuly speaking, it was probably bad combination of luck, rocky surface, and jumping down with spiked shoes.
