The Choose Your Adventure series is designed to be extra fun, social, and friendly for beginners, yet interesting for seasoned veterans.

At Choose Your Adventure events, everyone gets the same map with checkpoints marked all over it. Then, after a mass start, you can find as many checkpoints as you want, in whichever order you want! Just be sure to mind the time, since there’s also a time limit. Return to the finish on-time, or lose precious points for every minute you’re late. (Wear a watch!)

Choose Your Adventure is especially good for beginners, since if you can’t find a checkpoint, you can just skip it and keep going. Veterans are challenged by trying to identify the most efficient route to find all the checkpoints, and the mass start means head-to-head racing for some.

Thanks to the excitement-inducing time limit, everyone finishes around the same time, making post-event socializing a core feature of Choose Your Adventure events.

Come join the fun!


There is just a one-size-fits-all course for beginners through advanced runners. We’ll have a mass start and one map exchange. 12 checkpoints will be marked on the first map. Once you visit all 12 checkpoints (in any order you want) and return to the start, you’ll be given a second map with 12 more checkpoints (which you can also visit in any order you want). The total time limit is 75 minutes!

How does the scoring work?

All 24 checkpoints are worth the same amount: 1 point per checkpoint. The maximum score is 24 points. The first person or team returning with 24 points wins!

There’s a time limit of 75 minutes, and for every minute late, there’s a 1 point penalty.

Note for the map exchange: If you skipped any checkpoints from the first map, you cannot go back and get them once you take your second map. (This rule is to prevent an unfair advantage by collecting both sets of checkpoints during one loo


DO NOT TAKE SHORTCUTS THROUGH CORN! This rule applies to all maze visitors, not just orienteers. Anyone caught taking a shortcut will be disqualified. We want to be able to have events here in the future! All paths through the maze are about two meters wide. You should be able to complete the entire course without touching a single stalk of corn! Do not be tempted to take any “illegal” shortcuts, should you come across any.

The uncut corn is mapped as “area with forbidden access” (ISSOM 527.1 Olive Green).

From the start/finish tent, there is one “start” path and one “finish” path. Everyone will start into the start path (ie no entering the maze backwards).

Bring a compass, especially if it’s cloudy. Bearings won’t do much for you, but man, it’s easy to get disoriented in there! Also, bring a pen/pencil/marker/highlighter. You’ll thank me later.


08:30am – Registration Opens
09:00am – Registration Closes
09:15am – Wave Starts Begin
10:30am – Wave Finishes Begin

How do the wave starts work?

Usually at a Choose Your Adventure event, we have a mass start where everyone starts at once. However, since the maze only has one entrance and one exit, a mass start doesn’t really work.

Instead, we’ll assign specific start times to all participants (teams or solo) during check-in. Every minute starting at 9:15am, we’ll hand out maps to 5 participants (teams or solo). You’ll have 2 minutes to plan your route before you officially start the race and enter the maze.

Everyone has the same 75-minute time limit, so if you start earlier, you’ll need to be back earlier!

What’s an e-punch?

An e-punch records your race. At each control, you’ll dip the e-punch into an electronic box, which will beep and flash as confirmation. After you finish, you’ll download the e-punch at the download tent and get a receipt that show which controls you visited and how long you took between each; these are your “splits.”

Part of the fun of orienteering is comparing your splits with people who completed the same course, and discussing the routes you took!

Volunteers make these events happen! You can volunteer and participate on the same day, plus earn volunteer points to earn a free meet.



Park south of Elliott Road, where the farmhouse and country store are. From there, it is about a 250m walk, across the road, to the start and finish tent. There are toilets at the farm (near parking), at the start, and halfway through the maze.

The corn maze changes every year, and we have a 1:1250 scale of it, mapped to orienteering specifications. Most of the map is corn (out-of-bounds olive green), with a maze of paths throughout. There are a few other features, like firepits and a bridge/underpass.

Return to the Finish
All participants MUST return to the finish and download their e-punch or turn in their punch card.

Even if you have not finished your course, you must still return to the the finish and confirm with event staff that you have returned safely.

Out of Bounds
Some areas may be marked out of bounds. It is imperative to respect these boundaries to maintain our relationships with land managers. Participants MUST NOT go out of bounds. Any participant caught going out of bounds will be disqualified.

Course Closure
All participants MUST return to the finish by course closure time. If a participant does not return by course closure, event volunteers will begin coordinating a search party.

If you need a long time on the course, start as early in the start window as possible, wear a watch, and be prepared to cut your course short to make it back by the course closure time.

All participants MUST carry a whistle on the course. Complimentary whistles are available at the start tent (please only take one).

If you are injured on the course and need assistance, blow three long blasts to call for help.

If you hear a call for help, abandon your course to find the person in distress.

Part of the fun and fairness of orienteering is navigating your own course, so please be polite when you find a checkpoint and don’t holler that you’ve found it.
