The Amazing Maasai Marathon, Kenya

Who: 50 international, 100 East Africa residents, 300 Maasai runners

When: August 30, 2014 and August 29, 2015

Why it's unique: Running in the foothills of Mount Kenya, in lower Rift Valley bush teaming with wild game is highlight enough, but the true standout is the chance to run along side hundreds of Maasai, some of the fastest people on the planet. The race raises money (over $100,000 USD so far) for the Amazing Maasai Girls Project, a non-profit that helps pay for the high school education of Maasai women. []
