Get ready to brave the chill and embark on an unforgettable winter adventure at The Mammoth Ice Age 5K, set to take place on Saturday, January 17, 2026, in the charming historic town of Granbury, TX. This isn't just a race; it's the official kickoff to Granbury's Winter-Guest Tourism Season, inviting runners, walkers, and strollers of all ages and abilities to experience the heart of "the BEST Historic Small Town in America".

The 5K course is an accessible out-and-back route, starting and finishing at Hewlett Park and utilizing Granbury's paved Hike and Bike Trail system. Runners can expect a flat, tree-lined journey, offering picturesque views as they traverse through the historic scenery. Typical race day conditions in mid-January feature highs around 58°F and lows around 30°F, with only an 8% chance of precipitation, providing ideal crisp weather for a brisk run or leisurely stroll. Participants aged six and up will receive an official Mammoth Ice Age race shirt and a classic finisher's medal to commemorate their achievement.

What truly sets The Mammoth Ice Age apart is the festive post-race celebration, culminating in the much-anticipated Goosebump Jump into the frigid waters of Lake Granbury at City Beach Park. Just across the street from the finish line, this unique tradition promises a "100% chance of SNOW" (a fun, snowy atmosphere) and continues the winter revelry, making for stories you'll share long after your muscles recover. Whether you're aiming for a personal best in the timed event categories or simply looking for a fun, community-focused charity run, The Mammoth Ice Age offers an engaging and spirited start to the new year.
