Friday night (rest day after run 1) I had a flare up of a condition I have, so I took a second rest day yesterday to recover properly. I was looking forward to getting back out there again tonight, but OMIGOSH was that run tough!! Lungs started to burn on run 4 so half jogged, half brisk walked it. Managed to jog the remaining 3 runs but now my legs are wanting to commit murder to avoid further pain lol. Is the second run in a given week generally this tough or is it because I took the extra rest day? I don't want to slip back timewise on this program at such an early stage, but do you think I should take 2 rest days after run 3 as I would have done originally or just push on to week2?
Sorry for all the questions!
