I ended up going about twice as far as I normally do. My stamina is definitely improving. I reached the point where I normally turn around and I just kept going past it, past the other walkers, and surfers and swimmers and the old, tanned men sitting on the boardwalk.
Then I came home and had second breakfast since I realized my 200 calorie breakfast wasn't really enough to fuel me for the bike ride and a day of hauling stuff out of a house into a dumpster. Second breakfast was cereal, and I think some watermelon in a bit.
Farm stand later today to stock back up on vegetables.
