Mike Williams, 32, of San Diego said he came to race in the event because it offered double points.
"The track here is nice," Williams said. "It's for a good cause and they raise a lot of money." .
Williams, who races a cruiser, said he is making a comeback.
"I used to race when I was younger," he said. "But I've only been back for about six months now."
He said among the reasons he enjoys BMX riding is that it keeps him in shape and he has a lot of fun doing it.
Brock Russel, a 13-year-old fan from El Centro, said he likes to watch the racers jump.
"I like to jump," Brock said. "That's why I like it."
Brock said he regularly attends BMX events at the track because his brother plays baseball at the nearby Sunbeam baseball fields. When the games are over, Brock walks over to the track to see the races.
Ian Malcolm, 14, of El Centro has been racing BMX for three years.
"It's a challenge," Ian said. "I like jumping and having fun."
He said the sport is challenging and he enjoys it because he wants to improve.
"There's always someone out there who's better than you," Ian said.
To keep in shape, Ian tries to train as often as he can. He also races about three times a week.
Joe Nuñez, 29, of Brawley came to watch his 5-year-old son, Anthony, race.
"We come out here all the time," Nuñez explained.
He said Anthony is just a beginner. He began racing about six months ago, Nuñez said.
Nuñez said he thinks the Race for Life is a good idea because he would like to see an end to cancer.
"We know people who have had it," Nuñez said.
He said he plans on attending a second Race for life in Yuma in the near future.
The Race for Life is a nationally held event and membership at participating tracks is not required for a rider to race. Proceeds from the event went to the Leukemia Society of America.
