The Long Beach Sweetheart's Run - Valentine's 5K, 10K, & Half Marathon

The Long Beach Sweetheart's Run - Valentine's 5K, 10K, & Half Marathon takes over the coastline in Long Beach, California on February 14, 2027. The half marathon (13.1 miles) starts at 7:00 a.m., with the 10K and the 5K following at 8:00 a.m. Organized by CaliFlow Runs to promote health and wellness through community racing, the event welcomes runners, walkers and stroller pushers, who share the path with other users. Courses are well marked and supported with water stops and restrooms, every finisher gets a medal, and awards go to the overall and age-group categories.

Because the routes are flat coastal paths open to walkers, this one reads more as an accessible road race than a hard competitive test. That makes the 5K or 10K a sensible entry point if you are new to racing, and the half a fair goal for anyone who has been logging 20 to 25 miles a week. Build for about 12 weeks and keep one longer weekend run in the plan.
