Jingle Trails Challenge presented by Merrell
San Antonio, TX • December 13, 2025
Jingle Trails Challenge is at McAllister Park in central San Antonio. You'll run on dirt, rocks, roots and gravel. This is a trail race, be prepared for uneven surfaces. The routes are not stroller friendly. The 10K race is on the Blue Loop. Please note that there is construction on Blue Loop currently. This will cause the course to be a little longer than 6.2 miles and will detour us off the Blue Loop for a short amount of time. The 5K is on a separate loop through McAllister, mainly the Red Trail. The two courses will overlap as runners return to the finish area. Come dressed up to celebrate the season. The first 250 who register will receive a "Jingle Trail" beanie and all finishers will receive a finisher's mug to fill with hot cocoa!
