The Improve Every Day Half Marathon

Half Marathon in San Diego, CA · $25-$45 · ~1,000 runners

Race Info

The Improve Every Day Half Marathon is built around one idea: every mile out there is proof of what you’re capable of. This December 12th in San Diego, we’re bringing that to life on a looped course where every lap shows you 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.

Not ready for 13.1? Run the 4 miler instead. It’s one full lap of the same course, a shorter way to be part of the day and see what you can do.

Whether you’re running your first half, lining up for your first race, 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.

Prices go up as we approach race day:

October 1-31: $45 November 1-14: $55 November 15-21: $65 November 22-29: $75

What's included:

- lùth finisher shirt
