The Limberlost Challenge

The Limberlost Challenge 2019 promises to be better than ever. Experience the very best of trail courses.  The Limberlost Forest and Wildlife Reserve is the trail runner’s dream with its challenging terrain that will take you alongside pristine lakes, through a wetland with its tier of beaver dams, up and over some steep inclines and either tiptoeing or splashing through the occasional creek or mud hole.

The Seaton Soaker

Seaton Trail race is back again this year. We are very excited about staging this race, and it being the second race in the Ontario Ultra Series.
