I read somewhere that your body has about 20 seconds of max effort in it, unless you really train to extend that. Usually my first couple of sprints are pretty close to 20 seconds at max intensity, then the later ones get shorter and shorter.

Towards the end, rep 4-6, I might make it 50-70m before I feel my stride break.
And be careful with Bear Crawls- they are awesome, but your arms don't have the shock absorption that your legs do, so it's easy to jam your shoulders if you go too fast.
