Champoeg Extreme-O

Event overview

In honor of CROC's  25th anniversary (!!), this meet will be held on a map we've used since the olden days. Updated many times, the map area is relatively flat, both open and wooded. Water erosion has created some gnarly complications to challenge your orienteering skills. 

The late Mal Harding, co-founder of our club, loved this place and set some great courses here. He was fond of tricky navigation problems. Those who had the pleasure of doing Mal's Extreme-O a few years ago are still talking about it.

In honor of Mal, this year's Champoeg meet will feature a "Mal's Run" course, a special "extreme-O" course with lots of challenging and hopefully fun variations. 

Courses offered will be white (beginner), yellow (longer advanced beginner), orange (intermediate), and the extreme course. The "Mal's Run" course will augment a traditional course map with additional navigation challenges. The other three courses will be normal orienteering.

We will be going back 25 years in time and using retro pin-punching for this event. Maps for the traditional courses will be the latest, though. 

Come out and enjoy!
