Run For Breast Cancer 5K/10K/13.1 PHOENIX

Run For Breast Cancer 5K/10K/13.1 PHOENIX is held in Phoenix, Arizona, on December 12, 2026, raising awareness and funds in the fight against breast cancer. The half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run all start at 7:30 a.m., open to runners and walkers of every age and ability, with timing left up to you. Entry includes a race shirt, a finisher medal, a towel or gift, a digital training pack and access to local running clubs, sent directly to participants, and a virtual option is available.

An event with optional timing is a good place for a first race, because nothing about it insists you go hard. If you do want the clock, the 5K gives you a clean benchmark for twenty to thirty minutes of work, while the half rewards a proper twelve-week block with a weekly long run. Whichever you pick, the miles you record afterward add to what the event raises, so the entry keeps working past December 12.
