SoCal River Marathon
SoCal River Marathon race day weather
Cool start, warming finish
Runners will face a cool start at 54°F, warming to 62°F by the finish. A light headwind will be present during miles 3-6 and again from mile 8 to the finish, impacting pacing. With humidity at 58%, conservative pacing is advised to manage the rising temperatures. Pre-race conditions may feel cool, so a light layer could be helpful while waiting.
