This is the fourth annual race, and it has rained the previous three years.

If it doesn't rain this time, more than 1,000 riders are expected for the 8 a.m. start at Stars and Stripes Park.

There will be four distances: 10, 20, 50 and 100 miles. The two shorter fun rides will circle Lake Hefner, while the longer rides will follow an east-west route toward El Reno and Geary. All rides will finish at Stars and Stripes Park.

Participants in all rides will begin lining up at 7:45 a.m. Groups will leave the park at three-minute intervals beginning at 8.

About 500 riders had registered by midweek. About half were doing the 50-mile ride, one-fourth the 100-miler and the rest the shorter fun rides.

"This year, every finisher will receive a commemorative Streak medal," said Red Callaway of the sponsoring Oklahoma Bicycle Society. "The first 1,000 will also receive T-shirts."

Trophies will be awarded the fastest man and woman in the century ride, as well as medals for the top three finishers, both men and women, in each age category of the 50- and 100-mile events.

Four 12-speed Peugeot bicycles will be given away in drawings.
