Join Missy Giove, Marla Streb, Jacquie Phelan, and other brave women in their natural environment: the dirt. Some of them, like Missy and Marla, take on the pro downhill mountain biking circuit - flying down steep, gnarly trails at 50+ mph on tricked out, custom bikes. When they're not racing, they endure the tedium of travel, training, hanging out... Meanwhile, the sport's earliest champion, Jacquie Phelan, teaches frightened novices new tricks, while a wise mechanic advises "it's not about the uphills and downhills, it's all about the transitions" - a philosophy these athletes apply to racing and life equally. HardiHood reveals the emotions of the stars - and unknowns - who are the sport.
