16.94 miles, 4,676 feet, 5 hours 23 minutes: Troutbeck Church - Garburn Pass - Kentmere Horseshoe anti-clockwise - Sour Howes - Troutbeck Church. Overcast, cloud base initially about 1,500 feet, though it rose later. No wind, no rain. Temperature just right. Terrain damp, rocks slippery. Quite a few on the fells, including half a dozen other runners.
