Summer Solstice Run Half Marathon
Race Day Weather
Comfortable temps
Starting at 63°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 80% is worth noting for effort level, especially in later miles.

Race Info
The Summer Solstice Run is a half marathon, 10K, and 5K held along the beach path near 5400 E Ocean Blvd in Long Beach, California. The half marathon uses the same roughly 4.4-mile Long Beach coastline loop that organizer CaliFlow Runs uses for several other local races, completed three times to reach the full distance. The event began in 2025 as an evening 5K/10K glow run; the half marathon distance and a 7:00 AM morning start were added starting with the 2026 edition.
