9:10AM - from F500 - 90mins progression run - met Bob out on run for last 20mins or so. Included three hilly Hyannisport miles..a couple of figure 8 loops. Beautiful weather...chilly, but sunny & calm. Ended with 6:50 mile on track without undue stress. Felt excellent. Incline walking seems to be a good choice on recovery days. It may be that I've hit the age where this is better for recovery than an easy jog.
