A self-confessed sex-fiend, the Girl with a one-track mind reports her experience of a marathon runner (not safe for work):
… I had a fling with a marathon runner for a while – damn that boy had stamina. Stamina like you wouldn’t believe. …
But it just goes to show that there is a correlation between fitness, stamina and endurance in training, and the ability to last all night whilst shagging. I’m not saying that being able to run 26 miles will ensure your cock stays hard when you want it to – but surely it must help.
Well, possibly. The ones who aren’t too knackered from running 80 miles that week, perhaps.
