I knew the jump was big but I am so disappointed. So far it has been really hard but this run was impossible for me. I can't see how I will ever be able to run for more than 8 mins at a time. In fact I could even do the 8 mins tonight. I went really slow but still had to keep stopping. So disheartened. Maybe this just isn't for me and I'll have to settle with just doing week 4 repeatedly. I'm so upset. I do seriously admire anyone who was able to do it though.
