I wouldn't recomend sex in the middle of the night before a race... I found doing so did calm my nerves, but on the other side I was knackered the following morning.... maybe I should have stuck with just the once before bed rather than....
Once point about the article
male athletes were made to run on a treadmill 12 hours after having had sex. They showed no decline in stamina, or mental and physical performance
12 Hours is that 12 hours on a treadmill or 12 hours after sex ?
Duckinator, I think you should have kept that quiet, don't want the Mrs to come back and tell you it works!
