WHEN was the last time you saw a part-time male stripper dressed in a super hero costume leap across platforms in a mega obstacle course?

Those who had a crack included a former hurdling champion, a retired gymnast, a girl dressed as a bunny rabbit, a bloke wearing a Deadpool suit who's a part-time stripper and a fellow dressed as Tarzan.
