I saw a stat once that midfielders run about 5 miles in a game.
That’s why I played defense.
Now, cycling is probably the most demanding sport I ever participated in. 120 miles on the road can be brutal.
I dare not even think about the Iron Man. 110 Miles bike, 26.2 miles run and 3 mile swim? Something like that I don't know for sure.
I used to love it when some of the meat heads on the football team wanted to race me in the mile. They would get smoked. Even the running backs.
