Some of the nation's top action-sports athletes will perform demos Saturday in Fort Lauderdale to help Grind for Life, a charity for people with cancer.

Cocoa Beach skateboarder Mike Rogers founded Grind for Life in 2003, after fighting his second battle with sarcoma.

Attending celebrities include Andy Macdonald, who has been crowned skateboarding's world champion eight years in a row in the World Cup Skateboard Series; Mimi Knoop, a Cuba native with five X Games skateboarding medals; Lake Worth's Alex Sorgente, who won the Vans Am Pool Party in California; and Steve McCann, the only athlete to compete in all four BMX disciplines: street park, vert ramp, dirt jumping and the mega ramp.

Rogers, 47, was inducted into the Florida Skateboard Hall of Fame in 2009 and the Freestyle Hall of Fame the following year. He was first diagnosed at age 12, when he was growing up in Lake Worth and learning to skateboard. The cancer resurfaced in 2003, and Rogers, who spent all his retirement funds and savings on treatment, credits the action-sports community for helping him to afford treatment at Memorial Sloan-Kettering Hospital in New York.

So far, the charity has raised more than $150,000 and helped more than 200 patients.

The event will take place from 4 to 8 p.m. Saturday, Nov. 9, at Ramp 48 at 6290 NW 27th Way, in Fort Lauderdale. Admission is $5. Go to GrindforLife.org.
