Resolution Run - San Diego

Resolution Run - San Diego takes place in San Diego, California, on January 9, 2027. Three distances are offered: the half marathon (13.1 miles), the 10K and the 5K. Start times are not published with the entry details, so check them before race week rather than on the morning. The spread of distances means a group can enter across all three and still share the same morning.

Resolution races land in the part of January when good intentions are still holding, and the distance you pick should reflect the training you have already done rather than the training you intend to do. If you ran through the fall, the half is a fair test; if you are restarting, the 5K now and a half in the spring is the better sequence. Either way, one long run a week across ten to twelve weeks is what turns 13.1 miles from an event into a habit.
