4th Annual Cox Running Club Pi Day Half Marathon & 5K
Featuring the Inaugural Pi + 10 Half Marathon
Celebrate Pi Day with Cox Running Club on Sunday, March 14, 2027, at Woodshed Smokehouse in Fort Worth!
The Pi Day Run has traditionally featured the 3.14-mile Pi 5K, but because Pi Day falls on a Sunday in 2027, we are again expanding the celebration. For the second time, participants can take on the new Pi + 10 Half Marathon, covering a Pi-inspired distance of 13.14 miles.
Choose your distance, enjoy a fast and flat course along the Trinity Trails, and celebrate at the finish line with custom finisher medals, refreshments, and plenty of post-race pie.
Come for the run. Stay for the fun—and the pie!
