Important!

Signage

There will be lots of signs on course. Our arrows are orange UCI-shaped arrows on a white background. We also have an X for when you miss a turn.

 

These are used at our discretion and are not at every turn, so keep your head up, or use your GPS.

First Aid

Odyssey Medical will be on site to take care of any first aid issues. If you or a rider near you is injured during the race call Odyssey Medical (on number plate) or report to one of the Aid Stations.

What bike can I ride?

Any mountain bike that is trail worthy and safe!

 

We've even had some people have a great day riding a gravel bike or fat bike. (Just keep in mind that with a gravel bike, you may feel the bumps at bit more.)

Substance Projects' Weather Guarantee

Weather is always challenging and can completely change a race. So we developed the Substance Projects 100% Weather Guarantee: We guarantee that 100% of the course will have weather.

 

If any section doesn’t have weather we will refund you that percentage of your entry fee upon proof there was no weather.

Whining Policy

We have a strict "No Whining" policy. If it was all easy and downhill then it wouldn’t feel like you accomplished anything!

Inclusive Race

These are races for everyone! In the spirit of equity and inclusion we celebrate difference and especially encourage those who have historically been excluded from sport.

 

See our Inclusion Statement on our About Us page.

Cancellation / Refunds

There are NO REFUNDS for those who can’t make it on race day or for cancellation of the event for any reason.

 

If the event cannot proceed, registrants will have their entry carried over to the re-scheduled date or have credit for another Substance Projects Event.
