Brad Oxley and Scotty Brown are expected to compete in the International Speedway Motorcycle Ice Racing competition tonight and Saturday in the San Diego Sports Arena.
Oxley is the U.S. speedway champion. Brown is the current leader on the ice racing circuit.
The races, which begin at 8 each night, will be held for the first time in the Sports Arena. They are part of the ISMIR circuit, which is sanctioned by the American Motorcycle Assn. and includes races in Tacoma, Wash.; Oakland, and San Francisco.
The races feature 500cc speedway motorcycles equipped with special tires with metal studs to help grip the ice. The motorcycles do not have brakes because of the danger involved if the brakes lock in a turn.
Riders from six countries, including New Zealand and West Germany, are expected to compete.
There will be four heats in two divisions and a main event each night.
Twenty of the athletes who will be competing for spots on the U.S. Olympic canoeing and kayaking team will be in the San Diego area from Oct. 28 through Nov. 1 to consider Lake Hodges in Escondido and the Otay Lakes in East San Diego County as possible training sites.
