Haha, I was kind of the opposite. I was never really the fastest, but like an energiser bunny I could keep going and going. I remember an endurance course in yr 7 or 8, very few completed it but I decided to continue and completed it a second time by not stopping when we returned. I left with the next group just to see if I could. They stopped me at the third group because I was still not tired. I'm a big fat pudding now though
