I started running 16 months ago, ct5k done, Parkrun every week plus training runs of up to 10 miles. 10k races regularly. Now my dilemma is I am trying to conceive #4, #1 with new partner and since running. I think I may actually be pg as I'm late and showing all the signs but anyway. I am really struggling these last 2 weeks to run the distances I used to. Barely managing 6 miles on a long run and that's with walking breaks. I have a half marathon booked in 7 weeks time. Do I walk/run it or just forget it? Should I carry on running while pregnant, assuming I am? Should I just walk instead? Has anyone on here run whilst pregnant?
