1. The Big Five Marathon -- Limpopo Province, South Africa
June 21, 2014
The run: Held north of Pretoria on the 85sqmi Entabeni Game Reserve, runners of this combo safari-marathon adventure are treated to 26.2mi of wild animals, scenic savannah, and no fences! Yes, you're running with (or more likely, from) the lions. This means, of course, that you only need to be faster than one other runner. So that's encouraging.
The cool-down: Relax at the Legend Golf & Safari Resort, one of the world's few 19-hole golf courses. As in a real bonus hole, not a watering hole, only accessible only by helicopter. Tee off from 1,300ft up Hanglip Mountain.
