Overview
Course Description
For the first 2.5 miles, runners will run along Big Creek Trail before reaching Stanley Lake Regional Park. for the next 4 miles, runners will run through the winding trails within this scenic park before exiting toward the south trail turnaround point. It’s then a retracing of steps back from where they came from until ultimately ending back where it all started in Church Ranch Office Park. Note that this course emulates exactly the All-Out Beat the Heat Fest that took place in April. Upon registration, all participants can expect to receive a race shirt, custom bib, and access to free professional race-day photos. Once the finish line has been crossed, all finishers will also receive a commemorative finisher’s medal.
