Today was as warm as it's supposed to get all weekend, so I ran after I'd gone to Nacho's for lunch. That caused me some burpage on the run. I ran straight into the wind on the way out, so it was much nicer on the way back.
This was the first time I wore my replacement Garmin Forerunner 305, so I put on the heart monitor strap. It still doesn't seem to be registering consistently though. There were several places it dipped below 80bpm at places on the course where I don't think it could have been.
