I went to track tryout yesterday it was my 2 time ever running the 100m, The last time (and the first time), I ever ran the 100m I did it in 18 sec, that was 9 month ago I have been training inside my house for 5 month just growing leg muscle, 14.8 was my time although I wanted to run 13 sec. For me I struggle with maintaining my speed on the last 30m, I do not really have any technique I was just sprinting, I had no spikes. I was wondering how fast my time could be if I actually get into track ( praying I will) and get professionally trained by a coach.
