Got in 2.5 K (approximately) before work today. During this extreme heat wave, the weather is fine in the early morning. For the 2nd time in a week, my Garmin was "low battery" at the start. It died within a couple of minutes. Not sure why this happened as I am sure I turned off the Garmin in the last run. Watch is recharging as I write so there is no repeat during the weekend. I timed the run for 20 minutes. YTD = 735 K
