Check In & Start

Check in begins at 7:30 AM on Sunday, May 1, with a mandatory racer meeting at 8:15 AM. Race begins at 8:30 AM.


We will use manual timing for this event and there will be no live tracking. Results will be posted on UltraSignUp a few days following the event.

Course Description 

The route will begin with an 8k out-and-back on The Trans-Canada Trail, at which point you’ll begin running the Epinette trails to the Newfoundland Loop (see map linked below). After completing the Newfoundland Loop, you’ll return to the Epinette trail that leads back to the Finish (Parking Lot). This route is marked for general use, and minimal additional flagging will be added. You are responsible for knowing the route, and where you should be running.

Changes to the course are at the discretion of the Race Director to ensure the safety of participants and volunteers.

Aid Stations

When you begin this race, you should have everything with you to complete the entire race without aid of any kind other than water. Extra socks, food/nutrition/drink mix, blister care, anti-chafing goop, proper clothing, sunblock, enough fluid capacity. Ultimately, you are responsible for you!

However, to try and support you in doing your best, there will be a few aid stations on route.

After the out & back there will be a water & food aid station at the parking lot. Prior to getting onto the Newfoundland Loop you will hit your first “on trail” aid station which will be water & food. Once on the Newfoundland Loop, you’ll hit two aid stations. The first will be water only, the second, after Jackfish Lake Cabin will be water & food. After getting back on to the Epinette Trail, you’ll hit the last aid station which will once again be water and food.

An exact list of aid station food will be provided a month prior to the event in a racer email.

Drop Bags – Drop bags will be allowed and delivered to the South Newfoundland Aid Station about 30k into the race. Those will be the only drop bags allowed. Please note that these drop bags will return to the Finish only after that aid station has closed.

Crew – Crew are not allowed on the race course other than the start/finish area by the parking lot. Failure to adhere to this rule could cost your runner a DQ.

Cup Free Race – At the aid stations, there will be beverages available that you may not want to put in your bottles. If this is the case, please bring your own cup as we are a cup-free race.

DNF’s (Did Not Finish)

If you need to DNF, you must do so at an Aid Station. No one is coming along the trail to pick you up. Once you’ve DNF’d at an aid station, you will have to wait until that aid station closes before you’ll get a ride back to the Finish, no one will be rushing out to the the AS to get you.


On the trail, you are responsible for you! Please make sure you have enough fluids,  proper gear, appropriate first aid, and know how to use it. If you see someone in trouble, please provide help.

We will have first aid/first responder personnel plus rovers on bike, but communication is difficult in the area, and responding to an emergency could take hours.

**IMPORTANT** Please be aware of this fact before starting this event.
