Sulphur Springs Trail Race 2027

The Sulphur Springs Trail Race celebrates its 35th running in 2027 and is scheduled for Saturday May 29 and Sunday May 30 in the Dundas Valley Conservation Area in the City of Hamilton, Ontario (formerly the Town of Ancaster).

The event is built around a 20K loop course that combines groomed trail and moderately challenging single track. The terrain includes rolling easy hills as well as steep climbs and descents, with natural springs and streams along the route and the possibility of local wildlife sightings. Each loop provides over 500 m of elevation gain. A designated crew tent area allows teams to regroup, refuel and change strategy between loops.

The weekend features a range of individual distances and team relay options:

100 Miles
100K
50 Miles
50K
20K
10K
50 Mile Night Relay (up to 4 runners)
100 Mile Team Relay (up to 8 runners)

The race is presented by the Burlington Runners Club and is listed as a Western States Endurance Run 100 qualifying race in Ontario. The course location is on the Niagara Escarpment within the Dundas Valley Conservation Area. Visit the organization's website for the most recent information.
