I have just started week 7 of the programme and although I have enjoyed couch 2 5k so far I am now starting to struggle. I managed to do run 3 of week 6 which was 25 minutes but I can't seem to run for that long again. I have failed to finish the run twice now which is puzzling me as I know and have proved that I can do it. I only managed 10 minutes on Sunday, I tried again on Monday and only managed 18 minutes. It is hot weather at the moment which isn't helping but I am starting to get a bit disheartened as I feel like I am losing the endurance and stamina I have built up over the last 7 weeks. I really don't want to give up on the programme but I feel like I am now going backwards. Has anyone else been through a similar experience?
