AUGUST 10, 2019

This is it, the race of all races. One hundred miles across the high-altitude, extreme terrain of the Colorado Rockies, this event was created for only the most determined athletes. Starting at 10,152 feet and climbing to 12,424 feet, you’ll be challenged to catch your breath — while the views try to take it away.

As one of the most well-known mountain bike races on earth, getting into the Leadville Trail 100 MTB has always been difficult. LT100 Qualifiers are long and tough, with lots of climbing. They are similar to the classic course at Leadville in that they consist mainly of rugged jeep roads of gravel and dirt. A qualifier event could not only gain you entry into the LT100 MTB, but it could also boost your corral starting position in the Race Across the Sky!

Rider starting positions will be organized in color-coded corrals. These positions will be based on a finish time from the 2018 (year prior only) LT100 MTB race, a 2018 or 2019 qualifier event finish time, or if you hold a current USAC or UCI Pro Cross Country Elite license. Please enter finish times or license numbers when prompted during the registration process. However, if you race a qualifier after previously gaining entry, you MUST email Athlete Services at to inform them of your finish time so you will be placed accordingly. You will not be placed automatically. Corrals will be assigned as follows:


1000 mile buckles, 11 year jackets, and 2000 mile buckles will be presented at the awards ceremony on Sunday.

All age group awards will be presented at the awards ceremony on Sunday, August 10, at 7:30 am. There will be male/female 1st, 2nd and
3rd place awards in each age category: Under 19, 20-29, 30-39, 40-49, 50-59, 60-69 and 70 & over. Handmade trophies will be
given to the male and female overall champions. Finishers under nine hours will receive a large gold-and-silver trophy belt
buckle. Finishers under 12 hours will receive a silver belt buckle. All finishers under 12 hours will receive a finisher’s medal and
a custom finisher’s sweatshirt. There will also be awards for 1st, 2nd and 3rd tandems and 1st, 2nd and 3rd male and female
single-speed. You must be present to receive your award. Others cannot pick it up for you. Please see the Leadville Race Series Store Website to learn how to receive your award if you cannot attend the ceremony. After October 31st, 2019, buckles will no longer be able to be shipped. If you would still like your jacket or award after October 31st, 2019, please reach out to Kelsey Conine ( to get that product shipped to you.

*Please note that 2019 awards will not be shipped until the end of our race series season, September 2019.

Our races are Zero Waste events. Look for recycle and compost bins at every aid station and start/finish. Please discard any trash in an appropriate container. Intentional littering on the course will be grounds for disqualification. The course—on trails both public and private—travels past many historic sites and through areas of exceptional beauty. Help us keep them pristine.

We will be recycling all plastic, aluminum and cardboard during these races, and all our events. We’ll take care of this at the aid stations. At the start/finish, please ensure you place trash or recyclable materials in the appropriate containers, which will be well marked.

Leadville Race Series CREW shirtYour race checklist isn’t complete without your crew! Give them a way to commemorate this special experience with their own Leadville Race Series memorabilia. Visit our online store to check out our exclusive LRS crew shirts (pictured on right) to get your team prepared for race day!

At all the Leadville events crews are treated and appreciated equally with the entrant and are included in the Leadville Race Series family. Crew pets must be leashed and under control at all times. Crews are welcome at all aid stations except the turnaround. No crew bikes, please. Crews should allow adequate time to park and walk to aid stations. Crew vehicles are not allowed on any dirt road sections of the course. Riders are responsible for the actions of their crews. Crews and spectators will not be allowed vehicle access at the foot of Powerline or obstruct the junction of the paved road and jeep road where riders leave Powerline to head for Pipeline.

Crews will certainly want to be at the 6:30 a.m. start to assist their riders with any last-second needs cheer them on at the sound of the starting gun. Crews should proceed south on Hwy 24 approximately 3 miles, then west on Hwy 300 for a little less than a mile to CR 11/CR 11A “Y” intersection. Follow the slow sweeping right turn on the pavement, uphill and west, onto the gravel road that goes through the gravel pit area. Riders will be on paved CR11, the same road as crews for about a mile, so please drive slowly and use every caution on this stretch of road. Please allow your rider to clear this checkpoint before crewing. There may be some riders without a crew who would appreciate your help. Crews may furnish the replacement parts. Remember, you may help a rider with any need, except that the riders must complete the entire course using the original bike frame.

Crews should then proceed back to Hwy. 24, then south 11 miles. Turn west on Hwy. 82 for approximately 1 mile then left toward the Twin Lakes Dam. Volunteers will direct the parking. This area gets very congested, so we ask your help and patience, and that you follow the instructions of the traffic control volunteers without question.

A second crew access and parking area is the Mountain View Overlook parking area. Take the first left turn past the road up to the dam. There is a parking area at the end of this road.

We have another crew access point that may prove even better for some riders and crews. This crew area is located on Chaffee County Road 398A at the start of the climb to Columbine Mine Aid Station. Crews drive South on Hwy 24 to Granite. Turn right (West) just past the Granite store. Follow this dirt road to the marked crew area. This will give riders last second help before their big climb and again at the end of their descent. Using this crew point, you will avoid the huge crowds at the Twin Lakes Dam.

Riders will be crossing the dam, then checking in at the Twin Lakes Aid Station. You will have to carry anything needed for your rider to the crewing area. This same area will also be the next crew stop as riders will return to this aid station after an incredible climb to and descent from the 12,600′ Columbine Mine Aid Station. No crewing is allowed on that section of the course. Volunteers will attempt to meet their every need at this top of the world turnaround checkpoint. Once your rider has returned, reverse these directions.

From the very beginning, volunteers have made the Leadville 100 MTB possible. We truly appreciate all that our great volunteers do to make our races run smoothly and to make the racers’ experience unforgettable. If you are going to be in town for the 100MTB, we would love for you to join the family and pitch in. Thanks in advance for your help — we couldn’t do it without you!
