MAXXIS ESC Intense Downhill Series – Sunday
PLEASE NOTE WE ONLY ACCEPT CASH AT REGISTRATION AND FOR SWAG
Hello racers,
Thunder Mountain Bike Park and the Deerfield River Trails ask racers to be abundantly cautious if riding the Warfield Trails this weekend. They are not part of this year’s enduro; however, we expect that people will still ride there for fun. The new landowners are not happy with mountain bikers riding through the construction zone and are threatening to shut down access. The network can only be accessed from Riddell Road. Warfield Road and the construction project behind Zoar Outdoor are closed to mountain bikers, and access is STRICTLY PROHIBITED. Don’t be the entitled rider who ruins this for everyone!

ALL RACERS

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