Re: Whats harder running a marethon or playing 5 sets over 6 hours?
Nole would have a difficult time performing well at a marathon. How would he translate his skills (faking, cheating, bouncing) to the event. Plus, his secret weapon (injury time-out) would be a disadvantage. Wasting time would not help him win.
As far as Nadal is concerned, he would have to have his underwear surgically removed from his crack afterwards. Plus the bottle ritual would be difficult to manage.
I would not put my money on either of them.
