1. TRAIL CONDITIONS – The Bruce Trail is a fabulous hiking trail but it can be incredibly strenuous, runners should accept the fact that they may occasionally have to walk or even scramble due to trail conditions.

Trail conditions include:
  • Brief gravel packed trails and roads
  • Cobble stone beaches
  • Root and rock covered trails
  • Rocky steep cliffs
  • Rock crevices
  • High cliff edges
  • Uneven footing

2. All racers must check-in and pick up their bib & package on the morning of the event at the Tobermory Community Centre between 5:30am and 7:00am. We suggest coming to the Community Centre and parking, going inside to pick up your race-kit, which will include a free parking pass for the Legion Street Public Parking Lot. Drive to the Legion St. lot to park for the day and then proceed to the Downtown Tobermory Cenotaph for the Mandatory Pre-Race Briefing at 7:15am.

3. Aid Stations. Aid Stations will have water, sports drink, bananas, oranges + salty things. This is a cupless event, so participants need to have their own drinking vessel (min. 125ml) to fill up at aid stations.

At all times runners must follow the directions of race officials.   If you are withdrawing from the race, you must inform the nearest race marshal or official (friendly volunteer with race lanyard & badge) or else you risk being missed by our sweep team.  If you do not notify a race official,  a search & rescue operation will take place at your expense.

7. Due to the narrow trails and steep drop-offs, slippery rocks, etc. no dogs, push buggies, supporters or bicycles are allowed. Take care with and be courteous to other trail users. These are public trails and other users can use the trails while the race is underway. If you see a hiker or a biker, let them know you are coming and try to avoid disrupting their trail experience.  Mandatory gear is only a small whistle and 125ml of water carrying capacity, but we recommend carrying a small list of first aid supplies and enough hydration and nutrition for the event.

8. Runners are expected to be courteous and respectful to volunteers, other racers and visitors. Anyone found mistreating a volunteer, or member of the public will be disqualified.

10. Mandatory gear includes a whistle and minimum 125ml of water carrying capacity.

11. Safety on this course requires racers look out for one another:

  • If you leave the race for any reason, make sure you tell the nearest race volunteer.
  • If you encounter a runner in distress, offer assistance and/or report the situation to the nearest aid station.
  • Whistle protocol (three blasts if lost or in need of help, two blasts in response if heard)

Drop bags must be labelled with a runners name and bib number (bib numbers will be provided in final email update week of the event).
Half Marathon: Half marathoners can place any bags, jackets or extra layers in a bin with race management at their start line at Cyprus Lake if they’d like to bring these items with them for the bus ride. The bin will be available at the Finish Line to re-collect gear.

15. Spectators. Spectators are encouraged/welcomed at the Finish Line and along the streets in Tobermory.  Spectating along the course would be a challenge due to limited access to the trail and limited parking availability with Bruce Peninsula National Park. Parking in many spots within the National Park must be pre-booked. Please see this link for more details:
