I had a similar experience to yours. I was 12 and there was a local 5k. My dad was a into running so we did it and I puked at about 2.5 miles into the race. I won my age group though but don't remember the time. It was an out and back course and I remember thinking that the guys in the lead were flying! (at about 16:00 pace).
I think winning a trophy is what got me hooked.

Might have been 5th or 6th grade. Think it was a warm morning, and I remember struggling to finish the 5K in about 25:00. Then proceeded to puke - pretty sure it was my only post-race puke.
