Come Clean Leave Clean

The Minnesota Orienteering Club practices a Come Clean Leave Clean policy.  This helps us maintain a good relationship with the parks we utilize, sets a good example, and limits the transfer and spread of many of the plants that make our venues less enjoyable.



It takes a handful of volunteers to make each of our events successful.  If you would like to learn more about volunteering, please see our Volunteering page.  And as a reward, you'll get a free race entry the next Regular event you choose.


Race Results

Race results are usually published within 24 hours of the event.  View our Race Results page to see the results.
