Course and race notes
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.
