50 miles, 4000m ascent - a journey on foot from the very top of the Lake District at Caldbeck to the very bottom, at Cartmel, via the stunning Helvellyn Ridge and the western shoreline of Lake Windermere. It might not be the easiest traverse but it will be the most spectacular!
It will be a day never to be forgotten.
"Living in the Lakes this is a journey that inspires me to get out and run, I'm thrilled to be sharing some of the most spectacular landscapes and some of my favourite trails."
- Course planner James Thurlow.
