Seaside 5K
Race Day Weather
Comfortable temps
Starting at 60°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. Moderate humidity at 79% is worth noting for effort level, especially in later miles.

Race Info
The Seaside 5K starts at Solimar Beach on the Pacific Coast Highway and follows the oceanfront shoulder and bike path of the historic Old Rincon Highway on a short, mostly flat out-and-back. It is the shortest distance of race weekend and a quick way to see the Ventura County coastline.
