Hey,
I am running a 100m dash, and for the first 30 to 40 m, i am leading everyone by metres. However, when i hit the 50-70 metre s mark, others begin to catch me and then i do not do as well. I run the 100m around 12.7 seconds. I'm not sure if i have problems with my endurance or if i need to improve my overall speed. help me out, by giving me your imput and possibly some workouts. Thanks
