Leadville 100 MTB Race: Everything You Need to Know

by | Mar 14, 2023 | Racing

The Leadville 100 MTB race, also known as the Leadville Trail 100 MTB race or LT100 MTB, is one of the most well-known, loved AND hated ultra-endurance mountain bike events in the world. Taking place at elevations from 10,000 feet to ~12,000 feet, it’s a hugely challenging race that taxes your mental, physical and emotional strength.

What is the Leadville 100 MTB Race?

The Leadville 100 is a 100-mile race at high altitude in Leadville, CO, that is now owned by the Lifetime Inc.  The race is typically in mid-August, typically the second weekend on a Saturday.  The race website for Leadville 100 Bike is

How do I sign up for the Leadville 100?

This race is well-known because it is very hard to finish and even harder to get into! Registration is not as simple as just paying the fee (which is several hundred dollars!). You will need to qualify at one of a few races in the USA, enter the lottery, or you can go to their training camp or do volunteer hours. If you want to get there, you can definitely make it happen, but it’s not a simple ‘sign up and you’re good to go!’


Why is Leadville Hard?

The Leadville 100-mile MTB race takes place at over 10,000 feet of elevation (That is really high for a bike race) and involves longer climbs and more climbing than most people have easy access to. Temperatures can become quite hot as the day goes on, which creates a very hostile environment. To top it off, there’s also a strict cut-off time of 12 hours to get a belt bucket and 13 hours to be counted among finishers! So while pacing is important, there is a requisite fitness to get past the cut-offs established at one of the 7 aid stations on the course.

Oh yeah: It’s also actually 104 miles, not 100. So when you hit 100 on your computer, know that you’re not quite there yet!

2023 Update: You also can’t use aerobars at Leadville (if you were planning to) so that makes it harder too! (LINK)
