About the Cox Running Club Pi Day Half Marathon & 5K
The Pi Day theme runs all the way through this Fort Worth race. The course is flat, which suits both the half marathon and the 5K distances well, and the timed format means you get a real result at the end. The whole thing is built around a bit of math humor, and the organizers lean into it.
There is pie at the finish, which fits the occasion. Age group awards are part of the post-race setup as well. It reads like a race where the concept is the point, and the running is genuinely there to support it.
