Adventure racing team Nike from the United States is making its way through gear check here in Abu Dhabi. Here's a shot of athlete Sari Anderson signing her waiver for the event. Sari and teammates Mike Kloser, Michael Tobin and Chris Forne look healthy, happy and ready to take on the desert.

Sari, who rolled an ankle early on while racing this event last year, said she's more ready this time around. "Last year I'd just had a baby," Sari said. "I was in good shape then, but I wasn't as ready as I'd liked to have been for the heat and the pure exhaustion."

This year's format is similar to that of last year, according to organizers. Best of luck, Sari! Keep those ankles healthy!
