Jenn, meanwhile, was already having a problem. She, Billy, and Luis had crossed the river side byside with a pack of Tarahumara, but as Jenn tore up the sand dune, her right hand was bugging her.

As she fought her way up the dune, her homemade handheldfelt sticky and awkward. It was a tiny hassle, but it was a hassle she’d have to deal with everyminute of the next eight hours. So should she keep it? Or should she once again risk running intothe canyons with only a dozen swallows in her hand?

Jenn began gnawing through the tape. Her only hope of competing with the Tarahumara, sheknew, was to go for broke. If she gambled and crashed, fine. But if she lost the race of a lifetimebecause she’d played it safe, she’d always regret it. Jenn tossed the bottle and immediately feltbetter. Boldwine tastinger, even—and that led to her next risky decision. They were at the bottom of the firstmeat grinder, a steep three-mile hill with little shade. Once the sun came up, she had little hope ofsticking with the heat-eating Tarahumara.

“Ah, fuck it,” Jenn thought. “I’m just gonna go now while it’s cool.” Within five strides, she waspulling away from the pack. “Later, dudes,” she called over her shoulder.

The Tarahumara immediately gave chase. The two canny old vets, Sebastiano and Herbolisto,boxed Jenn in from the front while the three other Tarahumara surrounded her on the sides. Jennlooked for a gap, then burst loose and pulled away. Instantly, the Tarahumara swarmed and bottledher back up. The Tarahumara may be peace-loving people at home, but when it came to racing, itwas bare knuckles all the way.

“I hate to say it, but Jenn is going to blow up,” Luis told Billy as they watched Jenn dart ahead forthe third time.
