I’m going to take part in a Spartan Race. [Link]
Update: Just found out about the Tough Guy competition (video below) which is based in the UK. Here is a exceprt from Wikipedia:
It has been widely described as “the toughest race in the world”, with up to one-third of the starters failing to finish in a typical year.
After 25 stagings of the winter event, Wilson still claimed nobody had ever finished the course according to his extremely demanding rules. The race, and its summer equivalent, has suffered two fatalities during its history.

Sounds like a lot of fun and the UK version of anything is usually more hardcore than the US one (Dirty Sanchez vs Jackass).
