This weekend in King of the Hammers is Schampa King of the Motos. The 20-mile race, now in its seventh year, starts at 6 p.m. tonight under the blanket of darkness. It continues 9 a.m. tomorrow morning with a technical five-mile race. Later Sunday, it concludes with a desert loop of 100-plus miles for amateurs and 150-plus miles for pros. The best combined score wins. Only riders can work on the bikes. Racers to watch this year are Max Gerston, who finished second last year; Cody Webb, a three-time champion; and Andrea Crane, a local who has the home-field advantage.
