I have been running for about seven yrs but the past few months I have been struggling running just 3 miles. I dont know whats going on. I feel like a begginer. I do have asthma and the warmer weather makes it harder for me but this is really discouraging. Was wondering if anyone else has experiienced this and did you come out of it? I havent had the longing for races either the past 3 yrs and I keep having people wanting me to sign up for races. I wish I wanted to like I use to. I just dont have the desire to race but I do love running but I also would like to get that back but have yet to get there. Please any advice to getting my stamina back with running would be greatly appreciated. I teach bootcampl 2x week and workout regularly so its not from taking a long break. I do fine for shorter cardio workouts or up to a mile but then I lose it, no stamina or something. thanks.
