Op you are an absolute moron if you think
Gsp could do a triathlon no worries. It's a completely different type of cardio. LOL @ anybody in decent shape can do a triathlon. Give yourself an uppercut you naive fool. 
EpicConfessions - The reason I think Diaz is special is because ... well ... have you ever heard him speak?
Lol
32Hunter - Nah, Nick would smoke any mma fighter in a triathlon, probably any combat sports athlete for that matter.
Its funny that you said smoke...
gnomejeebus -Because he does triathlons. That makes him more athletic than GSP. No. I'm positive GSP could easily do a triathlon. I do triathlons. Not a big deal for anyone on decent shape. Personally I think GSP would prob smoke Diaz in a tri.
unfortunatly you've got a problem.
On one hand, you've got Nick who actually does ironman tri's and does WELL,
he even does well 6 days out from a title fight.
On the other hand you've got your opinion that GSP would do as well....
See that? Proof vs opinion.
Now, you claim to do Tri's. How did you place at the last ironman?
