To summarize, I’m still at it and haven’t quit.
I’ve been running 3 miles every other day, two laps around the park and the half mile home. I have only been timing the two laps at the park for a reference distance of 2.88 miles over varying terrain. (The sidewalk run home is pretty flat.) My times have not been varying much, so this is kind of discouraging, but I am still trying things to increase my stride length and speed.
My times for the 2 lap course have been 29 min 20 sec counter clockwise, 30 min 40 sec clockwise, 29 min 10 sec clockwise, and 29 min 20 sec clockwise last night. According to the Pace Calculator this comes out to a 10:11 min/mile, 10:38 min/mile, 10:07 min/mile, and 10:11 min/mile. Not so great for such a short distance, but considering my age I have been assured this isn’t bad for now. Running the course either counter clockwise, or clockwise is entirely different. Counter clockwise direction has a very long uphill run in the beginning and at the end, while clockwise has varying grades and one steep uphill, with a long downhill at the end. Both directions take me about the same time.
I will keep after it adding distance, and doing treadmill work to increase speed.
