Nitro Turkey Thanksgiving Day 10K / 5K

Nitro Turkey Thanksgiving Day 10K / 5K takes place in Richmond, California, on November 26, 2026, organized by Brazen Racing. The 10K (6.2 miles) and the 5K (3.1 miles) both start at 9:00 AM on trail, which makes for a single mass start and a compact morning — you are done and back home well before the day's cooking gets serious.

Shared starts across two distances tend to pull everyone out fast, so if you are racing the 10K, let the 5K field go and settle into your own effort in the first half mile. East Bay trail in late November is often damp, and a wet dirt 10K can run a minute per mile slower than the road equivalent without any loss of fitness on your part. Judge the day by effort, not by the split on your watch.
