I ran my first half-marathon without any training (I played basketball then) when I was 17.
One year later I ran the second and have been running ever since.
So I think I would say 18.
Almost all of my track PBs date back to 1999 but then I guess I never had the will nor health to train so intensely for the track.
Same goes for the road. It's been a few years since my best results (except for the Marathon but that's still a new event for me) but I haven't trained properly for any (again - except for Marathons).
I feel that I have a lot of PBs ahead of me still.
And I am planning on - may injuries stay away - attacking 4 or 5 of them in 2008. 1.500m, Steeplechase, 5K, 10K and maybe half/marathon or Marathon.
Wouldn't that be great...
