Godspeed 12

Godspeed 12 is run in Corpus Christi, Texas, on December 12, 2026. Three formats start together at 7:00 AM: the half marathon (13.1 miles), the 10k (6.2 miles), and a 12 Hour event in which you cover as much distance as you can within the time limit.

That mix means the same start line serves very different goals. The 10k and half marathon are fixed-distance races you pace against a target time, with a 10- to 12-week build and a weekly long run being ample for the half. The 12 Hour is a timed format, judged on total distance rather than finishing time, and it rewards patience, a steady walk-run rhythm and disciplined eating and drinking from the first hour rather than the sixth. If you have never done a timed event, start slower than feels right and let the day come to you.
