This area features some of the best terrain the Chicago area has to offer with lots of hills, contour detail, trails and great runnability with beautiful open woods.

We will have a Madnaess course and a beginner's course.

This is the second event of the 2017-2018 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. The 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.

The competition will go ahead through rain or snow.

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. Using their creativity, course setters will attempt to choreograph that elusive mass finish.

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:

Category Handicap
add 2
12 or younger
65 or older
14 or younger
55 or older
16 or younger
45 or older
19 or younger
35 or older


  • A 46-year-old female may drop 4 controls in the box.
  • 19-year-old male may drop 1 control in the box.
  • A 28-year-old male must visit all the controls in the box.


Public Transportation: Take Pace bus #381 from the 95th Street Terminal (in the middle of the Dan Ryan Expressway) on the Red elevated line at 8:30 a.m. Get off the bus at Moraine Valley Community College and walk west to La Grange Road. Follow La Grange Road south across the Sag channel and Hwy 83 to the forest preserve entrance just south of 119th street. On the return, ask someone in the parking lot to drop you at MVCC where return buses depart every 30 minutes all afternoon.

Driving: Take LaGrange Road-South from Stevenson Expressway (I-55). Go south on LaGrange Road past Hwy 83. Immediately after 119th street, turn right (west) into the forest preserve -- signs will be posted at the entrance.
