Here is the info copied from the email to the riders:
In order to spread riders out, reduce bottlenecks and increase safety on the course, we will be utilizing wave starts in 2021. This is a significant change from the mass start in the past, so please take note of your assigned corral and start time!
Wave starts will take place as follows:
Wave 1: 6:30AM - Gold AND Silver
Wave 2: 6:32AM - Red
Wave 3: 6:35AM - Green
Wave 4: 6:38AM - Purple
Wave 5: 6:41AM - Orange
Wave 6: 6:45AM - Blue
Wave 7: 6:49AM - White
IMPORTANT Course Changes
We will be making three changes to the LT100 MTB course. Please view below.
~ 43 Miles / 59 Miles - Riders will exit the trail, turn left towards Lost Canyon road and then turn right back towards the powerlines, taking the powerlines to FR398 (Lost Canyon) before heading up to Columbine. Riders will use the same route in reverse inbound.
Why? This ensures that we are not encroaching on private property.
~ 51.8 Miles - Columbine Turnaround - Athletes will turn around before the cabin at a larger area.
Why? This change will ensure we are not adding substantially different mileage, potentially jeopardizing 9-hr and 12-hr buckle cutoffs. Additionally USFS has new signage limiting vehicles near the historic turnaround. Lastly, the area is larger and allows for a more natural turnaround.
~ 68 Miles - County Road 10 - Riders will stay on County Road 10 for approximately 0.75 miles before turning left on CR136, taking a right on to Trail 1306 at mile 70.4.
Why? This allows for no head-on congestion on the single track from inbound leaders and outbound riders near the back.
