From the Organizer
The SYTY Half Marathon is built around one idea: every day is an opportunity to be better than you were yesterday. This December in San Diego, we're bringing that to life on a 4.1-mile loop course where every lap is a chance to prove to yourself how far you've come.
Half marathon runners will complete just over 3 laps. Each time you come back around you'll feel the crowd, feed off the energy, and find out what you're truly capable of. The loop format means you're never alone out there and the support never stops.
Whether you're running your first half or chasing a new PR, you're out there with people who get it. People who showed up for themselves the same way you did.
What's included:
Performance finisher shirt
Water stations on course
Electrolyte stations
4.1-mile loop style race
Early bird pricing is open now. Register today and take the first step toward your best race yet. Better yourself starts here.
