That is one of the most invalid lines of logic I've ever seen. Almost as bad as calling hand egg football.
I used to Play Gaelic football, ran track and field until a few years ago, and road races. Was pretty good, got a National gold medal hanging somewhere around here from about 4-5 years ago for 800m . Mainly I just go to the gym now, since I moved out to Uni I haven't found any clubs near enough for me to really be a part of them :/. New years resolution is to go sub 35mins for 10k though!
That is one of the toughest sports. I ran cross country alot and trained hard all my teenage years. Did some cross country skiing with my girlfriend when I was in Sweden and was absolutely exhausted. Respect.
