A 92 km (57 mile) point-to-point ultramarathon from Glasgow to Edinburgh primarily following the Forth & Clyde and Union Canal towpaths. The route is largely flat with minimal elevation gain, offering a continuous runnable surface on compacted path with occasional urban sections and bridges. Navigation is straightforward along the canal corridors, and the course is supported with aid stations positioned at intervals. The event is typically held in early autumn when conditions are cool but variable.
