re:xtraining

When i lived in the UK i competed in x challenges for a while, the  events went like this
run 2.5k
row 2000 mtr
climb 100 floors on step master
bike 10k
press ups 40 reps
sit ups 40 rep.
this was just one a many competitions that they had, back to back as fast as you can.....
so question time, does any body know of comps like this in the USA, i have googled but can't find any thing.
thanks
