About
Quarry Turkey Half Marathon/10K/5K is put on by Brazen Racing in Union City, California, on November 28, 2026. The card covers three distances on the same morning: a half marathon (13.1 miles), a 10K and a 5K. Start times are not listed on the entry, so check the schedule with the organizer before race day.
Because all three distances run together, this is an easy event to enter as a group with different goals. The half is long enough to reward a proper build, roughly twelve weeks with a weekly long run, while the 10K suits anyone whose autumn training has been steady but modest in volume. If you are using Thanksgiving weekend as a fitness check rather than a peak race, the 5K gives you a hard, honest effort without costing you a week of recovery.
