This is a special one,.. the views and scenery are amazing and the challenge immense... But its brilliantly organized by a very friendly and supporting team I would recommend it if you are up for a challenging day.

Well organised race, with brilliant on the ball staff and great atmosphere. The Ultra had a good array of textures and terrain on track and trail, with some technical and wet patches, but still accessible to novice distance runners. Looking forward to returning next year.

Awesome event, the atmosphere on both days was fantastic, staff were friendly and helpful as were the other runners. The scenery was breathtaking and the route itself was cheeky yet really good going. I will 100% be doing this again!!!
