Orienteering Map -- Current Map used for Permanent Courses at Waterfall Glen 1:7500 3meter contour interval. Event map revised in 2018.


This Waterfall Glen area has been used for the Forest Preserve District of DuPage County’s Permanent Orienteering Courses. While CAOC provided the map and assisted with the setting up of the Permanent Courses several years ago, this will be the first time that CAOC is will be using the 1:7500 mapped area for an orienteering meet. The mapped mostly wooded area is east and west of Cass Ave: Features include large and small trails, fire breaks (rides), large and small marshes and stream, and a small area of intricate contour details. Sawmill Creek passes around (on the east) or through (on the west) the mapped area. The woods are mostly light green to medium green runability.
We will have a Madnaess course and a beginner's course.

This is the first event of the 2018-2019 Winter Madnaess Series which features four individual races over the winter months. The format is very different from traditional orienteering as the race is a mass start. In general*, the mass start race is broken into three parts. The first is a set of common controls where the runners go head to head. They then enter the Madnaess box which features 7-8 controls. The intent of this box is to equalize the race for all levels of skill and as such each runner gets to skip a certain amount the controls based on their age and sex. Elite racers will have to cover all of them while younger or older runners will do less. Coming out of the box they then cover a number of common controls once again and if planned out properly most of the runners should finish very close to one another.

*Specific to December 9, 2018 meet, there will be two Madnaess Boxes (10 controls in each): Participants may chose the order of which box to go to first, but both boxes will need to be visited to complete the course. Prior to entering and after completing each box there are one or two mandatory control to visit.

Racers will count total results to determine overall 2018 champions. For runners who are unable to get to all four of the races to count for the total, this is not an issue as each race is a seperate competition so if you can only make one then come out a try.

For beginners and kids we will have seperate novice courses so bring them out.

The competition will go ahead through rain or snow (sleet, hail, etc.—you get the picture).

The Winter Madnaess Rules

  1. All events will have a mass start at 10:00 on the event day. You may start without penalty up to 20 minutes after the official start time. After that, your start time may be adjusted back to 20 minutes.

  2. The time limit is 90 minutes--all controls will be picked up after this time.

  3. At each event, every participant must sign an event waiver prior to the start, at registration time.

  4. Pre-marked maps are guaranteed to all who pre-register.

  5. Map cases may be purchased at pre-registration or on-site for $1.

  6. To ensure competitiveness for all participants, each event will use a handicap system called The Madnaess Box. Additionally, in total for all the box or boxes on the course, participants may drop controls equal to their handicap point total. Handicap points are awarded as follows:

The Madnaess Box

Each race will feature the infamous Madnaess Box, which consists of a set of controls labeled with letters (A,B,C, etc) somewhere on the course. Participants may attack the controls in the box in any order. Additionally, participants may drop controls equal to their handicap point total. Handicap points are awarded as follows:
