Tuesday tempo run

Morning run was 4+ miles with new NB test shoes. They fit like a glove and the ride feel great. Nice job. In the evening - after a day again spend among a huge pile of scientific articles - I drove to BWI trail and ran 3x2km tempo runs. They felt less easy, but times were close to planned (@ 5.35-5.25 pace).

Today's soundtrack has been non-metal.
