At anytime in the past you must have completed an ultramarathon, a road or trail race of marathon distance or beyond. If your longest race is a road marathon, finish time must be under 5 hours. If your longest race is a trail marathon, any finish time is acceptable. If you have completed an ultramarathon on road or trail, any finish time is acceptable. If you've done a road marathon in over 5 hours BUT it was at the end of an Ironman, that's acceptable. 

If you haven't already completed such an event then you have until 4th March 2024 to do so. 

If you have completed some sort of a long distance off-road event that doesn't quite meet our entry criteria, you must email team@highlandflingrace.org before submitting your entry.

Long fell/hill races and very long distance trail walking events may be accepted at our discretion. Please note that Half Ironman events are not sufficient and we will not accept GPS data such as Strava/Garmin/Suunto logs from training runs.

We are LGBT friendly. We are also QIA+ and non-binary friendly. You can enter our race as female, male or non-binary.  If you are trans, you can run in the gender category with which you identify, subject to compliance with current SA/UKA rules of competition, which the organisers must adhere to.  Recent changes to these rules of competition sadly severely restrict the ability of trans athletes to compete in the gender category they identify with. Please contact us for assistance if you are trans and unsure what this means for you. We will be assessing the event's association with SA/UKA ahead of the 2025 event due to these recent changes.  All event portable toilets and showers are gender neutral. 

We are fully committed to upholding all principles of the Scottish LGBT Sports Charter and aim to be as inclusive as possible. The organisers have a zero tolerance policy to any form of discrimination. ​

We are pleased to be supporting Haldane Youth Services this year.  Based in Balloch this registered charity (SCO038681) delivers after school activities for children in the West Dunbartonshire area.  

Their aims and objectives include providing opportunities to children to broaden and raise their aspiration using a variety of activities to positively engage young people into arts, culture, community, outdoor and healthy living activities.
