What keeps you motivated is your responsibility to discover, manage, nurture, grow, exploit, and have fun with.
Since retiring four months ago, am only running three days a week, but for much longer distances. A fluke that just happened without any desire or intention. Have run the longest distances in 55 years. Runs of 13, 12, 11, 10, 9, 8 and 7 miles. Anything less than 7 feels like cheating.
But yesterday was different. Only five miles. Three miles easy warm up, one mile time trial, one mile cool down.
Aimed for a six-minute mile. Came in at 6:04.
