Big Bertha Trail Run
Big Bertha is a 12 hour endurance run held on a 10 km loop around Bertha Loch. Participants complete as many laps as they can within the 12 hour period. Entrants may compete solo or as part of a team.
The route is fully marked and marshalled, with a water station at approximately 5 km. Chip timing is provided by Keep it Simple Timing Services and results are available in real time as runners cross the finish. A medic team is present on site and insurance is included for participants unless they supply their own. Finishers receive a medal created by The Workshop Aberfeldy. Prizes are awarded for the furthest distance and for female, male and nonbinary category winners.
Event facilities include free all day parking and refreshments at the finish supplied by Starfish Cakes and Bakery. The trails around Bertha Loch and Almondbank are described as varied. Online entry is offered.
