Spend three to 5 hours in the warmth of the day chasing a ball with no staff mates or reduction participant. I actually have carried out a lot of sports activities like rugby, boxing, cycling, swimming and competitive motocross racing tops them all, not on the basis that it is much more demanding, but does not have any rest periods compared to all the sports activities listed within the prime ten. Also to the one that said “like several motocross man may last for even ONE day of the tour de france within the alps … hA!” Most motocross riders do biking as their primary type of coaching … For everyone saying your sport is the “hardest you’ve got ever accomplished” it is also in all probability the only sport you have carried out at an elite stage. I speak as a tennis participant, and it annoys the hell out of me when individuals say tennis is about working round and hitting a ball. Tennis is among the most mentally, bodily, technically and tactically demanding sports out there, no query.
