Really impressive honestly given that he had done no field checking of the terrain. The area around 4 didn't make tons of sense to me, but that was partly me.
I also stopped to move 12 since it was 20m off the right cliff.
I've been testing running with insoles for plantar faciitis because I overpronate and a friend told me that could contribute to the Achilles pain. It's been amazing. It's reduced the pain from a 5-7 to a 1-2. So that looks like it was another mechanism affecting my Achilles.
