Cyclocross competitions are bicycle races over courses that include off-road terrain and obstacles that sometimes require riders to dismount and carry their bikes. Each race lasts for a set amount of time, usually 30 to 60 minutes depending on the level of competition. The rider who completes the most laps is the winner.
Saturday's event is staged by Zone 5 Promotions in conjunction with the Vancouver Parks and Recreation Department.
