Ran with the kids in the afternoon, and the some more afterwards near my house. Tapering for St. George. Tried out The Toy (Garmin 305). Very accurate. At least when properly charged - compared it against my "holy" marks, and it is right on. It showed 2.12 instead of 2.11 for the Slate Canyon Loop, but that course is very bad for a GPS with the hills.
Ran a tempo mile in 5:40 again. Felt good, very relaxed. HR hovered around 147 for most of it, got up to 153 when I pushed it a bit and was probably going around 5:35.
