Me Im a 52 yr man and run 50 or more week just a coincident. Need advise from you. Went on run when realize forgot something so went home but then decided needed to get in tempo for training. Got in 2 mi of 3.5 mi then ran into friend who is girl and we talk for 15 maybe 20 minute. Then started back up on temp and finished but only to 3 mi. not the 3.5 Then went home to worry and now still wodnering so want thoughts. Thank you
