The Syty Marathon

The SYTY Marathon is built around one idea: every day is an opportunity to be better than you were yesterday. This September 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 complete just over 3 laps. Full marathon runners take on more than 6. 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.

Both distances share the same course, so whether you're running your first half or going all in on the full, you're out there with people who get it. People who showed up for themselves the same way you did. That shared energy is something you can't find at a race twice this size.

We'll have water and electrolyte stations stocked throughout the course to keep you feeling strong every lap. Full marathon runners also get access to a gel station to power through the back half.
