I think you can go a few different ways:
A comination Skills, Power and Endurance/Fitness challenges would prove a true test.
I definitely think you need a boxer in there (I think Mundine would actually go pretty close to overall winner). A tennis player, golfer and swimmer would be great too. And what about a snowboarder or skiier?
Having said that, what about different versions:
Battle of the footy codes AFL v Rugby v Soccer v League?
Individual codes ie who is AFL’s greatest athlete? Run through a series of AFL skills but then put them through other sports challenges.
A women’s event would be good. I think some of our elite female athletes would take it to some of the blokes.
A teams event eg. Cricket v Iron Man v Swimming v League v Golf (maybe have one male and one female athlete).
A retired sportspersons event to see who has kept in shape after their playing days are over?!!
An International v National Sportstar event?
I was wondering about clauses in their contracts...did their clubs/sports allow them to compete. Were they covered in the event of injury? Cant see Everton letting Cahill
A great concept, lots of possibilities. I especially like the way it can encourage more active lifestyles across a range of sports.
