We're excited to again open a new orienteering location in the cool forest around Flagstaff. On Saturday, September 21, we're offering a number of events from our start/finish location on the east side of Ashurst Lake. We start the day with a 5+ hour adventure race. We'll also have a 2-hour Score-O, and a Bike-O.

We hope you'll consider joining us at our new event site at Ashurst Lake.


There are two developed campgrounds on the banks of Ashurst Lake. Fifty single-unit campsites are available. During peak season (summer months included), a campground host collects fees for overnight camping. Dispersed camping is also available off the road leading to Ashurst Lake. No dispersed camping is allowed within 1-mile of the lake.

The drive from Flagstaff to Ashurst Lake takes about 30 minutes. Flagstaff is a medium-sized city with plenty of hotel options.

Parental Consent:

Parental Consent Now Required (Click here for more information)
All participants under age 18 are now required to have a signed parental consent form on file with the club. You can complete the form before the event and either scan it and send it to us by e-mail or bring it with you to the event.


In order to promote pre-registration for our events, the Club has implemented a new pricing structure. Participants who pre-register for the event will benefit from our priority pricing. While on-site registration is still available, pricing for on-site registration is more expensive. In addition, we'll print some extra maps for each of our events, but we cannot guarantee a map for those who do not pre-register.

Pre-Registration is open until Thursday, Sep 19 at 11:59 PM. After the pre-registration closes, you can still try your luck and register on-site. We will have pre-printed maps for everyone who pre-registers. We cannot guarantee a map for those who register on-site.

What to Bring:

The list below is the minimum recommended for participation in the Score-O. The Adventure Race has a special list of gear needed to complete the race. For more details, see the writeups for the Score-O, Adventure Race, and Bike-O events.
  • Whistle (Mandatory for all. Available for purchase for $1)
  • Compass (Mandatory for all. Available for rent for $1)
  • Water. There will be water at the start/finish . We will also have one or two water stations on the course. However, you are strongly encouraged to bring your own water bottles or a camelback.
  • Sun screen. There is little or no shade on the course.
  • Sturdy hiking shoes and long pants are recommended. You may encounter cactus, cat claw, and loose terrain, especially on the Score-O.
  • Adventure Race: Optional Watercraft. There will be a short section of the adventure race where it's possible to use a watercraft. You're welcome to use any type of non-motorized watercraft you like, including kayak, canoe, paddleboard, pack raft, etc. Having a watercraft could be a slight advantage but it's not required.

2-Hour Score-O

In a Score-O format participants try to locate as many controls marked on their map as possible within the given time limit. The time limit for our Ashurst Lake event is 2 hours. 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. Controls are worth different points based on distance from the start/finish location and the difficulty of the navigation.

(Click here for general information concerning the Score-O event.)

You may start anytime after the course opens at 9:00 am until 11:00 am. Everyone, competitors and recreational participants alike, must be off the course and checked into the timer's table by 1:00 PM. The penalty for arriving after the 2-hour limit (or after 1:00 PM) is 10 points per minute.

Classic Bike-O

For our mountain biking friends, we're offering a Classic point-to-point Bike-O course. The course will take participants through the cool pine forest in the Ashurst Lake area. To make things interesting, we've included mostly double-track routes into the surrounding hills. Don't worry, the course won't include anything too technical.

Participants are allowed to take whatever time they need to complete the course up to the time the course closes (1:00 PM). We suggest you start as close as possible to 9:00 AM to make sure you can finish. We'll include a long course and short course to make sure everyone has an opportunity to finish in time.

5-Hour Adventure Race

For those of you who need a little more excitement, Saturday's events will include a 5-hour adventure race. The adventure race will include 3 separate sections: a short (less than 30 minute) section using optional watercraft or by foot, a 30 km bike section where ~10 km is mandatory, and to Score-O. The adventure race is open to teams of 1-4 individuals. Each individual participant should pre-register separately. Please note: Unlike many of our adventure races, we will not have UTM plotting for our Ashurst Lake adventure race.

Participants start the day navigating either by foot or using optional watercraft. The optional watercraft can be a kayak, canoe, paddleboard, pack raft, etc. All members of a team must navigate to one or more checkpoints. The trek/water section of the race should take less than 30 minutes.

Next, participants use a second map to travel to more points by bike. During the bike portion of the race, the controls are not located directly on roads or trails but are instead found on prominent features within 200 meters of the bikeable path. The bike section of the race will take stronger riders two hours to complete. We may throw a twist or two into the bike section of the adventure race to make things interesting. There will be mandatory and optional navigation points on the bike section of the course.

Finally, participants will try to visit as many controls as possible on the same map used for the Score-O. For this section of the adventure race, the scoring is not the same as for the Score-O. For the Score-O section of the adventure race, each control is worth 1 point. Participants should simply try to visit as many controls as possible before the 1:00 PM deadline.

Please remember that we will apply a 1-point penalty for each 5-minutes you arrive after the 1:00 PM deadline. If you arrive up to 1:04:59 PM, we'll deduct one point. Arriving up to 1:09:59 PM will reduce your score by two-points, and so on. We will mark you as DNF if you arrive after 1:30 PM.
