Tue 2/19 - AM 75 minutes, Denver Creek Path

Out and back run on what appears to be the only desirable place for running in the entire sprawling metropolis. Felt the thin air as expected, also felt a lot more soreness than expected in the legs and esp. the calf. Likely due to travel yesterday and lugging a heavy bag around much of the day. Much warmer than I thought it would be, climate at altitude always hard to figure for a flatlander.
