Shannon Trail Series

Event overview

The Shannon Trail Series is a three-race trail series in San Angelo, TX, held January 17 to February 21, 2026. The three races take place at different venues on separate dates: Middle Concho Park, Twin Buttes Boat Ramp, and San Angelo State Park (Chaparral Pavilion). Each race offers short and long distance options.

Distances, timing and awards

• Race 1 - 5K and 10K at Middle Concho Park (January 17, 2026)
• Race 2 - 5K and 12K at Twin Buttes Boat Ramp (January 31, 2026)
• Race 3 - 5K and 15K at San Angelo State Park (February 21, 2026)

Races are chip timed, but awards and race placings are based on gun time. Finisher medals are given at each race only on race day. Overall awards for Top 3 Male and Top 3 Female are given at each race for both distances.

Series scoring uses a descending points system (first place = 1000 points, second = 999, third = 998, and so on), with points added across the three races to determine series standings. Ties in points are broken by total raw time across the races. Series age group awards are given only after the third race and, starting in 2026, require finishing all three races to be eligible.

Additional notes: walking is allowed; pets are not permitted on course; strollers are not appropriate due to rocky climbs and narrow single-track dirt trails. Visit the organization's website for the most recent information.
