Supercross’ only female team manager builds trust among riders, mechanics

During the Monster Energy AMA Supercross Championship races, team managers are perched in a tower above the finish line and serve as spotters for their riders.

All of the team managers in the sport are men, except for Christina Denney of the Cycle Trader/Rock River Yamaha team.

For several years, she has called the shots in the testosterone-fueled sport of motorcycle racing.

Supercross is the stadium version of motocross, which is held on natural terrain. There no doubt will be thrills and spills after the racing starts Saturday at 6:30 p.m. at the Oakland Coliseum.

Some 500 truckloads of dirt, roughly 26 million pounds, have been brought in to build the track.
