What It Takes to Earn a Leadville Buckle

Every rider at the Leadville Trail 100 MTB is chasing a belt buckle. The big buckle is the one you dream about. The little buckle, the finisher’s buckle, means you beat the clock. In 2026 both the course and the buckle times changed, so we wanted to know what it really takes to earn each one.

The race was rerouted around the Willow Fire burn area. The new course is shorter and climbs almost 2,000 feet less, and the cutoffs tightened to match. The big buckle moved from 9 hours to 8 hours and 15 minutes. The finisher buckle moved from 12 hours to 11 hours and 15 minutes. So which is harder, the old course on the old clock or the new course on the tighter one? We built race-pace plans in Best Bike Split for every version and checked our own data to see how many riders are strong enough to hit each mark.

Two Courses, Two Different Days

Both courses still climb Columbine, and the new one actually tops out a little higher at 12,531 feet. Either way you spend the whole day racing at altitude, and that changes what your fitness is worth.

Why We Measure This in Watts Per Kilogram

Leadville has always been a climbing race. Columbine, Powerline, and Sugarloaf built that reputation, and on a climb what counts is your power divided by your weight. The 2026 course is easier, but Columbine still anchors the day, so climbing power still decides most of your race. Two riders with the same FTP finish far apart if one is carrying ten extra kilograms up that climb. So we put every target in watts per kilogram, the same way TrainerRoad’s AI measures your FTP.

One more thing to plan for. The FTP you hold at sea level is not the FTP you get in Leadville. Even a well-acclimatized rider loses about 10 percent of their sustainable power at the race’s altitude, and a rider who flies in cold loses closer to 15. That gap is worth minutes on the clock, and it can be worth a buckle.

What Each Buckle Takes

Here is the power-to-weight ratio you would need for each buckle, on each course, at that course’s own cutoff. These are sea-level numbers, the FTP per kilogram your AI detection shows at home. The blue bars are what you need if you show up acclimatized. The red bars sit higher because arriving cold from sea level costs you more power at altitude, so you have to bring more fitness to make up for it.

What That Is in Watts

Power-to-weight is the same target for every rider, but it turns into a very different FTP depending on what you weigh. The 3.4 big-buckle target on the new course is 231 watts if you weigh 150 pounds, and 324 watts if you weigh 210. Find your weight and read across.

How Many Riders Are Strong Enough?

We looked at TrainerRoad riders whose FTP was set the same consistent way, by our AI detecting it from real rides, and counted how many clear each bar. These numbers assume you arrive acclimatized. We split them by gender, because the watts-per-kilogram spread is different for men and women.

Age Matters as Much as Gender

Fitness like this is not spread evenly across the field. The same targets get harder every decade. The darker the box, the more riders in that group clear the bar.

Why Altitude Is Worth Training For

Look back at the two-color chart and you can see what showing up acclimatized is worth. It lowers every target by about 0.4 W/kg. That looks small until you turn it into odds.

Living at altitude before the race is the gold standard, but it is expensive and hard to arrange for most riders. Do what you can within your means to earn favorable altitude adaptations. Heat training, intermittent hypoxia from an altitude tent or a device like HEPOX, and getting to Leadville as early as your schedule allows all help. Any of them improves your buckle odds without adding a single watt.

Aerodynamics Matter More This Year

Climbing power gets most of the attention at Leadville, but aerodynamics have always mattered here. The long, mostly flat miles from the base of Columbine back toward town are where a slippery rider gains free minutes on a rider who sits up. Those miles are still in the 2026 course. What changed is the finish: instead of the Powerline climb, the new route takes Turquoise Lake Road up to Carter Summit and then climbs to the line. With Powerline gone and the flat sections mostly the same, more of your day is spent at speed, so aerodynamics count for more of your finish time than they used to.

Your position on the bike is the biggest lever, and it costs nothing. Practice holding an aero position with your elbows bent and your head and shoulders low, and build up to holding it for long stretches instead of a few seconds at a time. That is the cheapest speed on the course.

After position, look at your kit. Choose an aero helmet over a vented one, even though the vented lid feels cooler. Wear the tightest jersey and bib shorts you own, or a skinsuit if you have one. Loose fabric flapping in the wind is slower than it feels.

If you are chasing the big buckle or a specific time goal, the small stuff is worth it too:

• Aero socks
• Shoe covers
• Fork fairings
• Other small details that clean up the airflow around you and your bike

None of these replace fitness or a good position, but they add up when you are racing the clock.

What This Means for Your Race

• The clock got tighter, but the buckle got easier. The 2026 reroute cut enough climbing that both buckles are more attainable than before, even with the shorter cutoffs.
• The little buckle is a real goal. At 2.9 W/kg on the new course, more than half of men and better than a third of women already have the FTP. Show up fit and pace it well.
• The big buckle is hard, but it is not out of reach. Around 3.4 W/kg, roughly one in four men and one in nine women. That is a training target, not a genetic gift.
• Altitude is free speed if you earn it. Arrive acclimatized and you keep power that a cold arrival gives away.
• Get aero on the new course. With Powerline gone and the flat miles unchanged, more of your day is spent at speed. A low, practiced position and tight kit are close to free time.

Frequently Asked Questions

What time do you need for a Leadville big buckle?

On the 2026 course, the big buckle goes to riders who finish under 8 hours and 15 minutes on chip time. Through 2025 the cutoff was under 9 hours. The little buckle, the finisher’s buckle, is under 11 hours and 15 minutes on the new course, and was under 12 hours before.

How hard is it to earn a Leadville belt buckle?

For a rider who shows up acclimatized, the 2026 big buckle takes about 3.4 watts per kilogram of FTP, and the little buckle about 2.9. In our data, roughly 28 percent of men and 11 percent of women clear the big-buckle mark, while more than half of men and better than a third of women clear the little-buckle mark.

What changed about the 2026 Leadville course?

The route was rerouted to avoid the Willow Fire area. It is about 4 miles shorter, climbs roughly 1,900 feet less, drops the Powerline climb, and adds the Turquoise Lake Road climb to Carter Summit. The buckle cutoffs tightened to 8:15 and 11:15 to match.

Is the new Leadville course easier or harder?

Even with the tighter cutoffs, both buckles got slightly easier on the 2026 course. The reroute cut more climbing than time, so the big buckle dropped from about 3.7 to 3.4 W/kg for an acclimatized rider, and the little buckle from 3.1 to 2.9.

Does altitude affect your Leadville power?

Yes. Even a well-acclimatized rider loses about 10 percent of their sustainable power at the race’s elevation, and a rider arriving cold from sea level loses closer to 15 percent. Time at altitude, heat training, and intermittent hypoxia all help you keep more of your fitness on race day.

How do I get faster for Leadville?

Build the highest, most durable FTP you can, and keep your weight in a range that lifts your watts per kilogram. TrainerRoad gives you an adaptive training plan and uses AI FTP Detection to track your FTP from real rides, so you can watch your Leadville number get closer as you train.

Wherever your buckle sits, the plan is the same. Build the highest, most durable FTP you can, then hold it all the way up Columbine.
