Pi in the Sky

Pi in the Sky is a FAT ASS style trail event in Phoenix, AZ, organized by GhostHead Productions. The event is listed as an 8 Miler and the course description notes a 9-mile out-and-back route that starts and finishes at the Hope Bible Church parking lot. The route crosses the 51 Freeway onto Dreamy Draw Bikeway and continues through the Phoenix Mountain Preserves, including a summit of Piestewa Peak.

The course will be partially marked at critical junctions and Garmin coordinates are provided. Trails are rocky and often run on extremely technical terrain. Most of the route is exposed with very minimal shade, so warm or hot weather is likely in early June. Aid is minimal; a water fountain and restroom are available at the Dreamy Draw Trailhead, and participants are responsible for their own well-being. Timing will be done manually.

The event is limited to 50 runners and there is no entry fee. Participants should expect basic course markings, minimal support, and self-sufficiency on exposed, technical singletrack and connector trails in an urban mountain preserve.
