They are looking for male competitors between 18-35 - all sporty but with a good sense of humour, who are keen for a challenge (climbers? Ed). Sports include 100m running backwards, diving board long jump, downhill running slalom... "therefore all unusual sports but ones that you need to be fairly athletic to do well in." according to Endemol.
It will be televised on national television and the whole event will be about 5 days. Auditions are in May, in London.

"Prize money is fairy substantial - a few thousand for the top three at least."
