We will NOT have printed maps for this event as the course is easy to follow, so if you want one please print it. Please review the 2023 MAXXIS ESC Enduro rules on our website, there have been some changes, so it would be best to read everything.

All attached forms must be filled out even if you preregistered. Print them out, fill them in and save time.

$100 TIMING CHIPS We will be using our SIAC Fly By timing system for this event. Please note if you do not return the SIAC Timing Chip you will owe us $100. Yes, they cost that much. Other enduro series require the racers to use their own or rent them plus a deposit. We trust our racers until proven otherwise so please make sure to return the chip if you decide to leave early.

Please Note: GPS units on bars, stem or wrist may interfere with the SIAC Timing Chip so it’s best not to use one

Racers must be present at the racers meeting where we will activate their chips.

Please drive slowly through neighborhood while visiting Thunder Mountain, we do not want to upset the neighbors and please visit the local restaurants and let them know you are there because of the enduro race.
