We're excited to offer a day of navigation fun at Thorpe Park in Flagstaff, AZ. On Saturday, June 10, we'll present three events for your navigation practice: a 2-hour Score-O, a 2-hour Bike-O, and a 5-hour Adventure Race. The events let you practice your navigation skills using different modes of travel.

We start the day with our 5-hour Adventure Race. In the Adventure Race, participants start with a short trek to find points near the event start/finish. This allows teams to separate slightly before heading out to find points on mountain bikes. After the bike section, participants travel by foot to find as many points as they can.

For those of you wanting a more reasonable challenge, we're offering a 2-Hour Score-O, where participants travel by foot, and a 2-Hour Bike-O, where participants travel by mountain bike. In both events, participants try to find as many points as they can in the 2-hour time limit.


In the Score-O or the Bike-O, participants try to find as many controls as they can in a 2-hour time limit. Start times are between 8:00 AM and 11:00 AM. On the Bike-O, each control is worth 1 point. Controls on the Score-O are given different point values depending on their navigation difficulty and distance from the event's start/finish.

Individuals of all skill levels are encouraged to participate. For beginners, we'll be sure to set plenty of easier-to-find controls close to the start/finish location. We want to give you an experience that helps improve your navigation skills. For our experienced orienteers, we'll find ways to challenge your navigation skills with more difficult destinations.

Each control on the Bike-O is worth 1 point. For those arriving after the 2-hour limit, one point is subtracted for each 5 minutes a participant returns after the time limit.

For the Score-O, points are allocated based on navigation difficulty and distance from the start/finish. Point values vary between 10 and 70 points per control. For those arriving after the 2-hour limit, 10 points is subtracted for each minute a participant returns after the time limit.

Adventure Race

In the adventure race, teams of 1-4 (solos allowed) try their luck navigating by foot and mountain bike.

Pre-Race Briefing
We start the day at 7:45 with a mandatory pre-race briefing. All participants are required to attend the briefing. There are several main points:

  • To officially finish the race, participants must visit at least one control in each of the event's 3 segments: trek, bike, and foot.
  • Participants must complete the segments of the race in order: trek, bike, foot.
  • Teams are comprised of 1-4 participants. Solos are allowed.
  • In order to officially record a visit to a control, all members of the team must visit the control. Team members must remain within 100 meters of each other at all times.
  • Participants are only allowed to record visits to controls on their current segment of the race. For example, participants on the bike segment of the race are not allowed to record a visit to a control on the foot segment of the race.
  • Participants return to the transition area after each leg of the race for a quick passport check and map exchange.
  • Participants must finish the race by 1:00 PM. Late arrivals are penalized one point for every minute late. A team is marked as DNF if they arrive after 1:30 PM.

Mass Start
After the briefing, the event begins with a mass start at 8:00. All participants start the race at 8:00.

The first section is a short trek course, to help separate teams from each other. Three controls are available on a trek of ~1 km. Each control on the trek segment is worth one point.

Mountain Bike
Next, participants hop on mountain bikes for ~2 hours. Ten controls are available in a ~20km course. Each destination on the bike segment is worth 2 points.

The final segment of the race is the foot segment. Participants will travel to as many points as they can using the same map used in the day's Score-O. Each control on the foot portion is worth 1 point. Twenty controls are available in ~10 km.

Time Limit
There is a 5-hour limit for the adventure race. One point is subtracted for each minute a team arrives after the 5-hour limit. The team is marked as DNF if they arrive after 1:30 PM.
