First person to drop a barbell on their head wins. 

They did kill someone in the States when they had the bright idea of making swimming the last leg of a triathlon.

First person to need a physio appointment wins.

The order of the events is drawn in the day. 

Surf ski, board and swim. With run transitions. Why if the 6 orders possible.

My favourite is ski swim board..
