I can run at last at 10km/h (6mph) (1pt per km/h) 10
So you will post an astonishing 36 secs time in the 100m sprint...



I can reach my top speed (10 km/h, see above) very quickly
I can imagine.

I can run 10 minutes without being tired (1pt per minute) 10
On a serious note, there are people who can't do that at all.
