About This Race
The Mammoth presents a fascinating case of conflicting data that requires careful interpretation. The ITRA listing describes a massive 214-mile loop through California's Eastern Sierra, circumnavigating an ancient caldera around Mammoth Lakes with 21 aid stations and a 112.5-hour time limit. However, the website data clearly shows a different race series based in Texas, offering multiple distances from 5K to 100K at locations like Glen Rose and High Hope Ranch. Given the discrepancy between the ITRA data (which appears to describe an ambitious ultra-distance concept) and the actual operating website (which shows established Texas trail races), runners should verify current race details directly with organizers. The Texas-based events feature classic Hill Country terrain with generous cutoffs, family-friendly atmospheres, and traditional trail race amenities including finisher buckles for 100K participants. The race organization emphasizes environmental responsibility with a bring-your-own-bottle policy and offers volunteer credits that function as race entry currency. Multiple distance options make these events accessible to runners across skill levels, from the Mighty Mammoth 1K kids' race to the 100K ultra with its 26-hour cutoff.
Based on the website content, the Texas-based Mammoth races feature classic Hill Country terrain with mixed trail and road sections. The courses wind through pristine natural landscapes at venues like High Hope Ranch, a 1,000-acre eco-retreat dedicated to wildlife habitat protection. Terrain varies by distance but generally offers well-marked trails with generous aid station support and scenic routes through protected Hill Country ecosystems.
