Today I'm gonna do same as yesterday. I started at .25 mile at 2.5 mph. I've been upping distance or speed every day to get to 1 mile at 3.5mph. If the pulse monitor is close I'm between 120 and 150 bpm for the duration. Today's change will be a successive day as I've been skipping a day. If I can get to 20 min. daily for awhile I can make this a habit. Okay, I posted--I'll be back post-walk.
