Feliz Navidad Run 5K 10K Half Marathon by Califlow Runs

Feliz Navidad Run 5K 10K Half Marathon by Califlow Runs takes place in Long Beach, California, on December 19, 2026. The half marathon (13.1 miles) goes first at 7 a.m., the 5K and the 10K follow at 8 a.m., and a kids 400-yard dash closes the morning at 9 a.m. The staggered schedule means the longer race is well under way before the shorter fields set off.

Road distances a week before Christmas suit runners who would rather finish the year with a result than drift into January. The half is the one that needs a plan behind it: three months of regular running with the long run stretching toward 10 or 11 miles. The 10K asks for far less and still hurts in the right way, the 5K fits a base of a few weeks, and the kids dash gives the youngest entrants their own moment.
