Rules
1) All trails will be open during the race. It is up to you to yield to all foot/equestrian traffic at all times. Race hard, but please respect our other trail users. We are sending out a reminder to all open space users reminding them about the fundraiser and encouraging them to come cheer the racers on.
2) Each team member must sign a waiver at race check-in.
3) Only one pop up tent allowed per team. There will be no power or water at Whale Rock Trailhead. You need to be prepared for anything you may need: water, food, beverages, bikes, music, ...
4) If you choose, a racer can do back to back laps. Same as last year, we will start/finish at the kiosk just above the roundabout (no longer in the circle). The tracking board with all the teams listed will still be at the round-about. It will be your riders responsibility to put a check mark each time a lap is completed.
5) Hours of Power are 10 am - 11 am and 1 pm - 2 pm. You can have two racers on the course at a time. Great way to double your loop count.
6) Race ends at 4 pm. Any laps finished after 4 pm will not count.

Parking
Do not park at Whale Rock Trailhead. Drop-off and pick-up at Whale Rock Trailhead is okay. If you need to bring a vehicle, parking is available at the Red Rocks Country Club gravel parking lot.

Food and Beverages
- Beer: Kegs typically show up around 3 pm and are provided by The Red Rocks Team

Bathroom
A porta potty will be onsite near Whale Rock Trailhead.
