Think you got the legs for this one? Endurance is the name of the game as participants compete to finish two 19.5-mile laps at Flat Rock Ranch for some sweet singletrack goodness. Bring your climbing legs, because there will be a lot of it! If that seems like too much, we also have a half-marathon category as well. TheĀ STORM Miles of DisComfort MTB Marathon is the final race of the 2023/24 Hill Country Bicycle Works Texas Marathon Mountain Bike State Championship Series. MORE INFORMATION
