Pontius Navigator,
Well this was my thinking, I would surmise that the fellow posting on behalf of OASC is the more up-to-date source. But then the question as you stated is where would this 1.5 mile run take place? On a treadmill? That i feel is hardly a test of endurance. Though i wouldn't be one to complain if that is the case.
Either way it makes very little difference as i am training for all eventualities. I was mearly being curious, always nice to know what your up against.
