2013’s infamous Adventure Racing World Championship spanned the entire breadth of Costa Rica: from coast to coast (Pacific to Atlantic) and  border to border (Nicaragua to Panama).

Temperatures swung from from 5°C at night to a dehydrating 37°C in the day, and participants also had to contend with epic downpours, treacherous terrain and bitey crocodiles.

As a ‘bonus’, all the participants had to build their own bikes at the start line. This race takes flippin’ liberties!
