A long-distance Lakeland Trails ultra-distance day in the Lake District, built around sustained, cumulative climbing on fellside tracks and rougher trail. This sits firmly in the “all-day out” category: extended runnable sections broken up by long climbs and more exposed higher ground. Exact course specs (distance, ascent, checkpoints, marking vs GPX and mandatory kit) should be taken from the organiser’s official event page for the specific year, as this is where the definitive race-day rules and logistics live. (Note: I attempted to access the official Lakeland Trails site from your CSV link, but it returned a blocked/forbidden response in this session.)
