And heat (Calorific heat, not Jodie Marsh shows her tits Heat, that is) - That makes your HR rise, no?
Yes but would'nt that be constant after the first km or so?
In other news, I'm beating PB's all over the place.
I do a run around a small mountain (which involves a few hundred steps). Its probably only about 8km, maybe a bit more. But its a tough route. My best before was around 47mins (training time). Did 2 laps on sunday in 1hr:28mins.
