The Badwater Ultramarathon was run on July 24-26, and is considered by many to be the toughest race on Earth. The 135 mile course starts in Death Valley and ends on Mount Whitney and is known for it's extreme heat and dry conditions. StellarMag.com has posted a race report with details on the course and how the main competitors faired in the event.
I meant to post on the event a few weeks back, leading up to it, and of course also post the winners, but for some reason, the Badwater completely slipped my mind and I forgot it was even being run. With the recent heat we've been having here, I can't imagine trying to run a marathon, let alone an ultra.
