LOST VALLEY LUAU MTB RACE
20K / 50K / 100K
PRESENTED BY BMC
2025 DATE: SUNDAY, MARCH 30TH
Lost Valley Luau is raced on the Lost Valley Trail in Defiance, MO. This 11.5 mile loop has it all: flowing single track, technical root & rock formations, and some relentless double track. The race is run counter-clockwise, forcing racers to climb up the double track and the descend on the single track.
The surface of the Lost Valley Trail single track, even in the flowing sections, is extremely rocky, and as such the trail is among the fastest draining trails in the area. However, don’t be fooled, the early Spring date often brings a twist to trail conditions (prepare for the worst, hope for the best) as the Race will be run rain or shine.
New for 2025, the race will start/finish at the Lost Valley Lower Lot Gate, and uses the double track as a connector to the Main Lost Valley Loop. This lengthens each lap to 11.5 miles long, and every lap after completing the Beaver Time Section, participants will follow the double track back to the Start/Finish line to start their next lap.
New for 2025, the Race will now have 3 distance options:
Race 1 Lap in our 20k Category
Race 3 Laps in our 50k Category
Race 6 Laps* in our 100K Category
*The 100K Distance will have a Last Lap Call at 2:15pm (6.75 hours from Start Time). At this time all remaining Participants who cross the Start/Finish line, who have not completed 6 Laps, will have their race reduced to one final lap. This will allow most riders holding over a 8.5 mph average pace to get in a full 6 laps.
Timing by best timers in the business MSE Racing.
