Description

Members of Wun Club are already training for this year's Sulphur Springs Trail race. We're entering a team of 8 into one of the most famous trail races in Ontario with each of us taking on one of the eight 20km loops of the trail.

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 ft of elevation per 20K loop. Expect to be challenged on this (mostly) double track trail system as you are supported with three fully stocked Aid Stations along the way.

This race is the Longest Running Ultra Race in Ontario, dating back to 1993.  

If you haven't trail ran before, it's not too late to get into it but you'll need to start training now. We've fallen in love with the sport and are confident you will too.

Message us on Discord if you have any questions about entering. We'll be vetting everybody who wants to join the team to make sure you'll be safe to do so.

Saturday May 24th
05:30-05:40 Pre-race announcements for ultra and relay runners
6:15 am 100 Mile solo & 100 Mile relay runners START


Sunday May 25th:
08:15 50M, 100K, 100 Mile, & relay runners - LAST LAP Cut-off

We'll be training together in preparation for this race. You can run at whatever pace you want but as a team, we need to make it back before the cut-off, 26 hours later so most of us should be running between 2-3 hours per lap.

We'll be sharing detailed preparation notes in advance on the Discord once you've registered.

We'll figure out rides in the Discord prior to the event so we're not offering an official shuttle at this point but everyone who needs it will have a ride.
