Apr. 7: Ride the Divide at Summerfield Cinemas

Only the very fit and/or very crazy can even fathom racing the Tour Divide, probably the world’s hardest mountain bike race which runs 2,700 miles from Banff, Canada, to Antelop Well, N.M., at the Mexican border. Self-supported for usually three weeks, cyclists race against the clock as much as their own breaking point. ‘Ride the Divide’ documents the race and screens Thursday, April 7, at Summerfield Cinemas.

551 Summerfield Road, Santa Rosa. 7pm. $15. 707.522.0719.
