I am would like to participate in Track and Field.
that's cool! I used to do it in high school. I'm good at running, jumping and throwing
Great,  I believe I would just want to run, could you do only one sport?
yes, sure. Track and field includes road running, cross country running and race walking
What kind of distances can I run?
you can do long distance running, it's a continuous running over distances of at least 8 km or 5 miles
what about shorter distances? I think I would prefer that.
I'm not sure about other distances. you can actually do race walking if you don't wanna run. i know there is middle distance running but i don't know the length
And what bout springs like Usain Bolt do?  Those seem like a lot of fun.
he runs 100 metres and 200 metres
