Went climbing at Rocks and Ropes with Boris, Cristina, and Linda. Did a few 7's, made good progress on an inclined 8, and completed an 8- at the end (with a few breaks because my hands were so tired).
Right heel hurt all day - guess 40 minutes of running without any arch support yesterday put it over the edge. I've had minor heel pain there before (notably, the first time I ran in Mudclaws, and also after doing calf raises), so it seems to be mild plantar fasciitis related to calf tightness. Fortunately, I can barely feel it if I walk in my comfy shoes with soft insoles, so this should not take too long to heal. Once that happens, I'll start wearing the Vibrams again, but take it much easier this time. The left foot is completely fine, but the right one, which is weaker, needs a slower approach.
Running around on sandy trails, and partly in terrain, testing out my new Vibram Five Finger shoes. This includes half an hour in the morning, then two more bouts of 12 minutes in the afternoon (first in the Vibram, then in sneakers). For the first half hour, the vibram felt absolutely great! Lightweight, grippy, and padded enough to protect me from sand and gravel. But the construction also has downsides - certain types of thorns can pass through the bottom of the shoe.

6 hill intervals up a sandy road (about 210 meters in total, maybe 15m climb?). Feet hurt, but the padded shoes and soft ground (no rocks) made it tolerable. Times were 1:12, 1:10, 1:07, 1:07, 1:05, 1:05. Quads were feeling tired on the last one, so I stopped. Knee was ok on the way up, but hurt if I tried to run back down, so I walked. Lots of rest. :)
