Course And Trail Description

The Sulphur Springs Trail Run takes place in and around the Dundas Valley Conservation Area in the City of Hamilton, Ontario (formerly the Town of Ancaster). This park is managed by the Hamilton Conservation Authority. All race events will take place on a 20K loop consisting of approximately 97% trails and 3% roads within the conservation area. The 10K event will use only the western portion of the loop.

While you are running the Sulphur Springs Trail Run you will be traveling through the beautiful Dundas Valley Conservation Area which is part of the Hamilton Region Conservation Authority park system and includes part of the famous Bruce Trail from Queenston Heights to Tobermory (approximately 800K).

 The park is open to the public on race day so be courteous to and aware of other users. This will include runners, bikers, horseback riders and walkers. Bear in mind that you will be running through wilderness and may encounter deer, coyotes, raccoons, skunks and others. IF YOU ENCOUNTER ANY WILDLIFE, MAKE A LOT OF NOISE. DO NOT ATTEMPT TO APPROACH ANY ANIMAL .

More that $60,000 from the proceeds of our Sulphur Springs races have been donated to help support the Dundas Valley Conservation Area.

Take a look around you as you run to see the legacy you are leaving behind thanks to your participation in this race.

 Below, the 2013 race director Joe Hewitt is presenting a cheque for $10,000 from the proceeds of the 2013 race. One project this money helped to fund can be seen in the background. This equipment brought in over 20,000 tons of screenings to repair and upgrade many of the low lying areas of the trail.
