Lore & Trivia
The Lakes Sky Ultra is a skyrunning event in the English Lake District — technical mountain racing on exposed ridges where scrambling (using hands as well as feet) is required. The course follows ridgelines that Wainwright walkers know intimately but at a pace and commitment level that transforms familiar fells into genuinely challenging mountain terrain. When conditions deteriorate — and in the Lakes, they always can — the exposed ridges become serious mountaineering territory.
- ▸ Some sections involve actual rock scrambling — hands on rock, Grade 1 terrain.
- ▸ The course traverses some of the Lake District's most iconic ridgelines including Helvellyn's Striding Edge.
- ▸ This is one of the few UK races that requires demonstrated scrambling ability for entry.
- ▸ The Lake District's combination of short but steep mountains creates a uniquely intense race.
- ▸ Established in 2015.
Skyrunning in the Lake District — exposed ridges, scrambling, and the constant threat of English weather turning Alpine.
