  • Athletes will be racing their fellow 99ers for awards and Leadville qualifier coins.
  • If you are registered for the 99er and finish the race you will be eligible for both merit-based Leadville coins and the drawing for the additional coins. 
  • Each Leadville Qualifying Series race provides 25-100 qualifying slots to the Leadville Trail 100 MTB, based on the total number of registered riders at each qualifier event. Half of the qualifying spots will be allocated based on the top age-group performances and half will be drawn among riders who have finished the qualifier race within the allocated cut-off time.
  • Qualifying slots will be distributed at the Awards Ceremony. There will be 25-100 slots per qualifying event. Qualifying slot winners MUST BE PRESENT, as the roll-down qualifiers rule will be in effect at each event. All qualifier slots will be awarded and redeemed on race day. You must pay your entry to the LT100 when you accept your slot. You will have the option to register for the current year or the following year’s LT100 and must decide when accepting your qualification slot. All entries into the LT100 are non-refundable and non-transferrable.
  • ** The corral placement chart for the 2024 LT100 MTB based on prior performances at Leadville Race Series events can be viewed below. **
  • 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 a previous (see corral chart) LT100 MTB finish/qualifier finish. Please enter finish times when prompted during the registration process. If you race a qualifier after previously gaining entry, you MUST email Athlete Services a direct link to your individual results so you will be placed accordingly. You will not be placed automatically. Corrals will be assigned as follows:


99er awards will be 3 deep in each category:
