Race page

Glen Lyon Ultra Marathon is a 31 mile foot race held in the stunning remote Glen Lyon in the Perthshire hills.

For information on the trail race option see its page.

The route starts with a loop of Loch Lyon with around 6 river crossings which means your feet will get wet. On completing the loop of Loch Lyon you will pass through the start/finish area to collect your drop bag. The route then climbs the hill over into the remote Glen Lochay were you will complete a high and low level route before climbing back over the hill and down into the finish in Glen Lyon.

Glen Lyon Ultra Elevation

The route is 85% off road with a middle section of tarmac. When off road, attention should be given to foot placement as trip/slips and falls have been the main cause of patching runners up in the past.

There are several water crossings in the first 8 miles where your feet will get wet.

In the event that the water crossings are in spate from heavy rain a route B will used.

Water Station/Checkpoints

  • Water Station 1 approximately 8 miles
  • Halfway Drop Bags 15.5 miles
  • Water Station 2 approximately 20 miles
  • Water Station 3 approximately 26 miles
  • Finish approximately 31 miles

Glen Lyon weather can be unpredictable. In years gone by we have had minus 2/snow and taps aff +70. Please check the weather forecast and pack for all weathers.

Runners will be required to carry mandatory kit which will be confirmed in the race briefing sent out 3 weeks before the race. Check the race rules below for an idea. This will include a small first aid kit for running repairs. Runners are reminded to read and understand the full race briefing and should ask any questions if they are in any doubt about any information. “I didn’t know” is not an excuse and will lead to disqualification.

The race fee includes a race memento, goody bag and a technical race t-shirt or vest, for collection on race day.
