2025 SSTR RUNNERS GUIDE

This unbelievable 20K looped course is a hidden gem inside the Dundas Valley Conservation Area of Ancaster, Ontario.

With wildlife teeming through this old Carolinian Forest, and waterfalls cascading over rocks along the course, your legs may not even notice traversing the over 500m / 1500 feet of elevation per 20K loop. Expect to be challenged on this (mostly) double track trail as you are supported with 4 fully stocked Aid Stations along the way.

The Sulphur Springs Trail Race 100K and 100 Mile events are now Western States Endurance Run Qualifying Races. We are proud to be the newest in Canada and the First race in Ontario to serve as a WSER 100 Qualifier. More details are available below.

This is the longest running Ultra Race in Ontario, dating back to 1993. Our 2025 race promises to be the best ever, be sure to grab your bib early; we are planning to sell out again this year!

This creates a very energized finisher experience!

Our '100 Mile Club' offers our 100 Mile solo runners an opportunity to store gear, rest between loops, fuel up with special foods and drinks, and a place to keep their pacers happy and dry.
