I am a college freshman who is very very serious about running. My 5k time is 15:54 and dropping. I run 67 miles a week for a D3 school. I am scared to date a girl because i feel like it will distract my rapid success on the track. I am also scared to have sex because i feel like it will waste energy for some of my long runs and workouts. Does anyone else have the same concern/thoughts? Is this normal?
