This is a CUP-FREE event! Please bring your own – leave no trace!

As this event is all-trail, road shoes are not recommended.

Music and Headphones:

  • 50K & 25K:
    Your course runs into the Dufferin County Main Tract, which is open to the public throughout race day. Some trails are used by mountain bikes, some by horses. As a result we cannot recommend any headphones that would interfere with your ability to hear other trail users.
  • 10K & 5K:
    We prefer the sound of the forest, but if you must run with music, Please have only one ear bud in or keep the volume low and be aware of your surroundings at all times.

More details will be provided in the week before race day, but there will be a combination of self serve (water only) and peopled aid stations (water, electrolytes, trail snacks). This is a cup-free event. 50K and 25K runners are required to bring their own cups or hydration packs.

In the event of rain everything will proceed as planned. A little mud is good for the soul.
