day or two in advance.

Mountain Bike Info

Course lengths are approximate (subject to change) and are measured

ski-o style, that is, shortest rideable distance (not straight line).

You may ONLY travel on established roads and trails and through open

areas (yellow or yellow with white dots) - you may NOT ride off-trail or

cut through the woods between trails on foot, even if it is only a short

distance. Use caution if riding on roads as there may be car traffic,

and watch out for two-way traffic on trails. Downhill riders yield to

uphill riders, and bikes yield to everyone.

The beginner course sticks to the wider (ski) trails. While this is

off-road riding, it isn't particularly technical and you could probably

get by with a gravel or hybrid bike if you don't have a mountain bike.

The navigational difficulty is closer to yellow than white - most legs

involve navigating through several junctions though route choice is

fairly straightforward.

The intermediate course requires some singletrack riding, though this

can be minimized depending on route choice. The advanced course makes

more extensive use of singletrack. The singletrack is mostly ranked

intermediate; it tends to be rooty but there aren't many technical features.

Foot Courses Info

Format: Scatter-O

In a Scatter-o, you decide which controls to visit and in what order;

the goal is to find those controls as quickly as possible. There will

be several course "lengths" based on the number of controls to find e.g.

find any 10 or 17 or 24 controls. You'll be placed in the appropriate

category when you finish, so no need to decide in advance. However,

there's no bonus for visiting extra controls - if you get 16, you'll be

included in the 10-control category.

While all of the controls are on trails, you can short cut through the

woods if you want. You must also STAY OFF private land - the park

boundaries are indicated by a dashed purple line with purple hatching on

the outside. Public roads (shown with brown infill) can be used.

Instruction is available at all events, just ask at the registration table. Feel free to bring friends and family.

Pre-packaged snacks, fruit and jugs of water/Gatorade will be available.

Don't forget to sign up to volunteer and pre-register.

See you in the woods!
