Packet Pick-up & Mandatory Racer Meeting

Clarion Copper King Hotel and Convention Center, 4655 Harrison Avenue, Butte
Packet pick-up will NOT take place during the 6 p.m. race meeting but will resume after meetings conclude
Mandatory racers meeting, Friday, at 6 p.m. at MAC
All racers must be present to pick up racer packet, sign event participation waiver, and be informed of any last-minute course information, safety protocol, and drop bag delivery
The Butte 100 is not responsible for drop bags provided to the race after packet pick-up is concluded (e.g., race day delivery)
Unfortunately it is not an option to have a friend pick up your packet because they cannot sign your waiver; ID required at packet pick-up.


Aid Station Drop Bags

The Butte 100 is a non-supported, wilderness race and the use of racer drop bags is strongly encouraged-race supplies other than water and Hammer Heed should be considered supplemental
Racers are allowed one 1-gallon zip-lock bag per aid station
Bags must be in the possession of the race no later than 9 p.m. on Friday, July 25, to guarantee delivery to the proper aid station
Markers will be provided at packet pick-up to label drop bags with your racer number. Other recognizable designing/labeling is encouraged to help aid station organization and efficiency
Note: Mechanical support is the responsibility of the racer


Course Marking

Markings will be ribbon tied to trees and other obvious locations to the racers. They will consist of yellow/red Butte 100 flagging (similar to ‘caution tape’) and 8”x 8” yellow arrows staked on racer’s right. We strive to mark ‘reassurance’ flags every 300 yds to 1/2 mile along course.


Cut-off Time

Aid Station #6 100 Mile racers only – 1:00 pm
Aid Station #10 All racers – 7:00 p.m.
Racers that drop must either arrange a ride, or patiently wait until drop shuttle arrives. Only full or near-full car loads will be transported back to the start/finish
Every dropped racer MUST notify race volunteer/timing booth at the finish line immediately upon arrival and return their timing chips.


Drop Bag Pick-up

Aid station volunteers will deliver all contents back to the Start/Finish area as soon as they are dismissed from the course


Racer Safety

Racer safety is of the utmost importance; however, race personnel can’t be everywhere at all times. It is imperative that everyone look after each other throughout race day. It is the racer’s responsibility to report incidences immediately to race.
A minimum of one ambulance is on call at the start/finish area throughout the race
Immediately report any odd/suspicious looking behavior before, during, and most importantly after the race to any volunteer, ambulance crew, or USFS law enforcement
In case of any emergency, the entire course receives some degree of cell phone coverage and all aid stations have phones to call emergency personnel


CDT Policy

Racer registration indicates your consent to follow the established Continental Divide Trail Policy outlined by the USFS: “Bicycle use may be allowed on the CDNST (16 U.S.C. 1246(c)) if the use is consistent with the applicable land and resource management plan and will not substantially interfere with the nature and purposes of the CDNST.”


Fire Policy

The Butte 100 will commence rain, snow, or shine. In the event that an outside influence creates any difficulty, organizers will make every effort to provide an alternate course if possible. Cancellation is an extreme and very last option. There will be no refunds or carryover of registration fees or entry positions in the event of a race cancellation. Organizers will mail all contents of the swag bags and the race jerseys to all registered participants in a timely manner.


Race Policy

Racers must complete the race on the same bike
Drop handlebars and/or cross-bikes are not permitted
All racers must compete and follow the rules in the race of which they are registered. Failure to do so will result in a DQ.
