In August, ultrarunners Hal Koerner and Mike Wolfe attempted to break the record running 223 miles on the John Muir Trail from Whitney Portal in the eastern Sierra Nevada to Yosemite. They battled sun, heat, lack of oxygen, and a missed rendezvous with a resupply, but in the end they did it, with a final time (and new record) of 3 days, 12 hours and 41 minutes.

I caught up with them throughout the run, at the beginning from Whitney Portal, a key points along the run, and at the well-deserved finish in Yosemite. This is what it looks like.
