I can easily hit 10.5s in 100m sprint when I am not training but after a two or three days training my calves start hurting like hell.I cant do it in even 11.5s because of my calves. I play soccer on regular basis and my calves feel okay with that. My P.E teacher advised me to do calf raises that was also of no help.Do you guys know any solutuin to that?
btw is 10.5s okay...??
