Event Overview
The Leadville Trail 100 MTB is the holy grail of American mountain bike racing. Held in August 2026 in the high-altitude mining town of Leadville, Colorado, this 100-mile out-and-back course is legendary for its difficulty. The race starts at 10,152 feet and reaches a staggering 12,424 feet at the top of the Columbine Mine. Founded on the principle of grit and perseverance, the race awards the coveted silver and gold buckles to those who finish under 12 and 9 hours, respectively. The atmosphere is one of pure endurance culture—thin air, dusty trails, and a community of 'Leadville Legends' that support every rider from the pro line to the sweep riders.
Course Details & Terrain
The course is not overly technical in terms of 'singletrack'—much of it consists of fire roads and doubletrack. However, the 'technicality' comes from the altitude and the sheer physical demand of the climbs.
Key Sections:
- St. Kevin's: The first major climb, right out of the gate. It's steep and sets the tone for the day.
- Powerline: A notorious descent on the way out and a brutal, soul-crushing climb on the way back. It is steep, loose, and often requires a 'hike-a-bike' for many riders.
- Columbine Mine: The centerpiece of the race. A 10-mile climb that takes you above the tree line. The air is dangerously thin here, and the final miles to the turnaround are incredibly steep.
- The Return: The final 20 miles include the return over Powerline and a long, deceptive grind back into the town of Leadville.
Who Should Enter? (Beginners vs. Experienced)
For Beginners: You must respect the altitude. This is not a race for someone who has never ridden 50+ miles on a mountain bike. If you are a Leadville novice, your primary challenge is finishing within the 12-hour cutoff. Proper pacing and a strict nutrition plan are your best friends.
For Experienced Athletes: The goal here is the 'Big Buckle' (sub-9 hours). This requires an elite level of fitness and a seamless pit-crew operation. Experienced riders will focus on weight-to-power ratios and aerodynamic efficiency on the fast fire-road sections. Every gram of weight on the bike matters when you're climbing at 12,000 feet.
Coach Raye's Race-Day Pro Tips
- Altitude Acclimatization: If possible, arrive in Leadville at least 7-10 days before the race. If you can't, arrive as late as possible (the night before) to avoid the 'day 3' altitude slump. Hydrate more than you think is necessary, as the dry mountain air strips moisture from your lungs with every breath.
- Pacing the 'Out': It is very easy to go too hard in the first 40 miles because the descent off St. Kevin's and the flat sections near Twin Lakes feel 'easy.' Do not exceed your Zone 3 heart rate. If you burn your matches before the Columbine climb, your race is effectively over.
- High-Carb Fueling: At altitude, your body relies more heavily on carbohydrates for fuel. Aim for 90-100g of carbs per hour in liquid or gel form. Solid food can be hard to digest when oxygen is scarce, so keep your nutrition simple and easily absorbable.
