Is it normal to have a burning sensation in my thighs DURING a sprint?
In my school athletics team I did 100 metre sprints and my thighs don't hurt at all during or after the sprint. I also wear Skins half tights which help compress the thigh muscle areas. I wear the half tights under my cycling shorts so could lactic acid build up be ruled out? (http://www.skins.net/au/en/HowSkinsWork)
How could I sprint for longer? Or do I need to live through the pain?
