12.42 miles, 3,232 feet, 4 hours 16 minutes: Fairfield Horseshoe clockwise from/to Ambleside, going to the left/west of the 1st, 2nd and 4th tops above Nab Scar on the ascent, then to the south west of Dove Crag and down the race/east side of the wall and the rock step on the descent. Sunshine, blue sky, some thin high streaky clouds, hazy in the distance. No rain. A moderately strong wind from the south east. Terrain mainly dry with good grip. Lots of walkers on the fells; I saw 5 runners in the valley and 9 on the fells. It was very warm when out of the wind.
