Obviously not for longer distances...did 5x1k today to see where I was for my 5k fitness.
4:10, 3:53, 3:50, 3:53, 3:50--the last lap was definitely hard, the first four not so bad. First lap was by feel and I realized I should have pushed a little more.
Am I in sub-20 shape? 60s walking rest.
40-50 mpw, 1025 miles for 2024, 1-2 workouts a week, the rest EZ. 6-7 days of running w/cutbacks every 4th week.
