5K Trail Race

Grey Mare's Trail Race - 5K

Saturday 18th September 2021 – 10:30 start (just 30 minutes after the Ring of Steall Skyrace™ start - get back in time to cheer in the first finishers!)



Skyline Scotland - Grey Mares trail race


Heading out anticlockwise from our grand start venue at the Ice Factor in Kinlochleven, and initially sharing the same first section with the famous Vertical Kilometer® (Mamores VK) race, you will feel like this is the beginning of something big, despite the seemingly modest 5km distance. There is something else about this route you see – a short but super-steep ascent on a memorable zig-zagging rocky trail in beautiful woodland. Once past the Mamore Lodge, the route levels out on a wide trail to give fantastic views west over Loch Leven and the surrounding Munros, before switching sharp left steeply down an exciting single-track section of the West Highland Way. All that remains is the final flat run-in through Kinlochleven, to the crowds at the finish. Britain’s toughest 5K trail race? We’ll let you decide.

The inaugural race received some stunning feedback: "Was it really just 5k? That was fantastically action-packed!"

Location & Accommodation

Please consult this page



Event parking in the centre of Kinlochleven will cost £3 per car - payable by card on arrival. ​

*sorry, our arrangement with the landowner does not entitle us to permit overnight stays in this car park, so camper vans cannot be parked overnight. Please take a look at our location overview page for some campsite suggestions. 



The registration marquee will be in the Event Village next to the Ice Factor in the centre of Kinlochleven. This is where mandatory registration and issue of competitors' race number will take place. Competitors should allow at least 1 hour to complete the registration process. Registration is open between 09:00 and 10:00.


The Start

The start line of each of the Trail Races is in the Event Village next to The Ice Factor. There will be a real buzz at this location with the added atmosphere of the big international Skyline Scotland® races starting and finishing in the same location.

Start time: Saturday 18th September – ready at 10:15 for a 10:30 Start

​Please note: Participants must ensure that they are in the start pen and ready to go 15 minutes before the start time.



Family, friends and members of the public are welcome to support competitors at the Event Village, which will be a hive of activity! 



Any retiring competitor must return to the Event Village in Kinlochleven by either reversing the race route, or continuing along it; whichever is fastest. Once arriving at the Event Village, it is essential that a retiring competitor reports to the finish to check-out of the race timing and safety systems.



Any competitor requiring emergency assistance should alert a race marshal at the nearest Checkpoint along the race route. We expect fellow competitors to stop and assist another competitor in an emergency. 



There will be a course sweeper following behind the last competitor.


Course Closure Time

Any competitor falling behind the average speed to complete the entire course within the course closure time may be retired at any checkpoint along the race route. The course closure time is generous as we want this race to be inclusive and encourage novice and slower runners. The course closure time is 12:00

  • I know my limitations and I am experienced enough to make a reasoned decision whether or not to start the event and/or to retire from the event rather than jeopardise my own or other people’s safety;

Event Rules

It is the participant's responsibility to know and follow these rules:

  1. Participants must follow the Universal Event Rules applicable to all events organised by Ourea Events.

    We would like to highlight the following from the above, as these are the most likely to incur penalties or disqualification through ignorance:
    • Marked Mandatory Routes: Participants must follow the marked (i.e. flagged, waymarked or signed) mandatory routes without deviation. They may go directly from each marker to the next, but deviation (such as cutting corners in zig-zags or taking a direct line to a later marker) is forbidden.
    • Mandatory Kit: Participants must comply with any Equipment List and carry all mandatory items as specified at all times. Any transgression may result in not being allowed to start the race or disqualification.
    • Support Runners: Participants are not allowed support runners. Any person attempting this will cause their officially entered associate(s) to be disqualified immediately and all the runners involved may receive life bans from Ourea Ltd events.
    • Race Number: When issued, participants must display one race number on their front at all times and (when issued) a second race number must be attached to their rucksack. Race numbers can be obscured by waterproof clothing only. Race numbers must not be folded.
    • Littering: Any participant seen dropping litter will be disqualified.
  2. Rubbish: Participants may not dispose of any rubbish or food wrappings along the route. The only location at which rubbish can be deposited is at the finish. Failure to do so will result in disqualification.
  3. Headphones: Participants must NOT wear headphones or listen to music at any point during the race. This rule will be strictly enforced.
  4. Trekking Poles: Participants may use trekking/hiking poles EXCEPT in the following places:
