Limberlost Forest Hosts the Limberlost Challenge and is set  amongst a year round wilderness haven with twenty private lakes and more then 10,000 unspoiled acres of mixed forest. 
Limberlost offers a variety of recreational activities. They have over 70km of hiking trails along with over 25km of groomed ski trails and a 18 hole disc golf course. Limberlost is open to the public at no charge every day of the week. They offer seven lakefront cottages, four outposts as well as 55 campsites all surrounded by extensive woodland trails and sandy beaches 


You will run through technical areas that will require the nimblest of footwork and on trails that allow you to open up to your best speed, plus everything in between. You will marvel at the extraordinary beauty of this privately owned Reserve that we are so privileged to enjoy. It will leave you breathless in more ways than one!

We promise you a well marked course, enthusiastic volunteers and a post-race meal that you will write home about.
