Run for the Mountain School at Fort Tuthill. Grey toe socks, black running skirt, philly short sleeve, Annapolis half hat. Carried hand-held water bottle, one Gu at about 5.2m. Tough breathing the whole time, RBE of 21, 22, 23 for most of it or 31, 32 on a lot of the uphills, occasionally 52 or 53. Breathing pattern helped, but so dry and so hard to get enough air into my chest while trying to push the pace and run quickly over the rocks without tripping. Got some good pictures of Dennis, Tristan, and Rebekah after I finished. Pretty day.
