If people didn't think I was loony, they will have doubts now, just run my most enjoyable run with the biggest smile on my face after reading your comment Runnith.
A male will always run better under the eyes of a woman as they are trying to show their strength and stamina to prove they could be a good breeding mate. Whereas when a male is being watched by another male the brain knows that we are running and will think that we are being hunted and are trying to escape, so the brain will make us think we are working harder than we really are, thus conserving our energy as we may need that extra energy to fight, should we be captured.
