The only locally-produced half marathon in the City of Tucson, this beautiful course brings you to the heights of Sentinel Peak and cruises past the historic Mission Garden and along the scenic Santa Cruz riverpath.

Choose the challenge of a half marathon or a fun 4-miler.  

Still too far? Bring the whole family and walk the Cox Charities Family Mile or have the little ones join the SAR FitKidz Mile, free for all 12 and under.

Top runners are eligible for prize money, and all participants can enjoy live music, a post-race beer garden, and an after-party at the super-cool Mercado San Agustin Annex, a perfect post-run venue, with music, food and more.
