Get ready to push yourself to the limit at this summer trail racing event in San Antonio's Pearsal Park, which offers three challenging distance options: a grueling 25k with two loops through hilly front trails and relentless back sections, a demanding 10k that covers most of the first loop before an early turnaround, and a 5k option. All courses feature water and Gatorade stops to keep you hydrated as you battle the heat and elevation changes. Whether you choose the longest, middle, or shortest distance, expect a serious test of your endurance and mental toughness.
