Highland Fling Ultramarathon

Event overview

The Highland Fling Ultramarathon takes place on Saturday 29 August 2026. It is a point-to-point, way-marked trail ultramarathon along the southern section of the West Highland Way, running from Milngavie to Tyndrum through Loch Lomond & the Trossachs National Park. The course distance is 53 miles (85 km), with about 2300 m of ascent and 2100 m of descent. The route is roughly 90% trail and 10% road. The event uses live chip timing and offers luggage transport from the start to the finish. Event buses are available before and after the race for an extra cost. At the finish there are heated marquees, free homemade food and drinks, free showers, free post-race massage, an afterparty in a marquee (BYOB and donation bar), sponsor stalls, and free official event photos.
