11.81 miles, 3,364 feet, 3 hours 57 minutes: Rothay Bridge - Miller Bridge - Low Sweden Bridge - rock step - Low/High Pikes - High Bakestones - Scandale - Red Screes - Roundhill Farm - Ambleside. Initially quite overcast, with the cloud base at about 2,000 feet, sunnier later, with the cloud base rising so that it only caught a few of the highest tops. No rain, virtually no wind. Terrain anything from dry to saturated and slippery in places. I saw perhaps 20 walkers on the fells, and 2 fellow runners.
For the Rydal Round there were 2 marshals on Low Pike to make sure the runners were on the east side of the wall. All were on the correct side apparently. They could see that some of the runners took a different line from the others and often gained 4-5 places by doing so. I was trying to find this line today - there are several grassy trods that look advantageous, but finding them from the top could be tricky.
