My entire family is into athletics. My little brother ran 38 min on the 10k and he was 10 years old at the time..
Like I said though, build matters a lot when it comes to running. In fact it matters with all activities. I'd love to have a great squat PR, but unfortunately I don't appear to be built to squat much.
35m is a decent time by the way, but it's nowhere near elite.
