Hi, this is my first post. I really enjoyed week 1 and was looking forward to moving up to wk2, but my knees - which were a bit achey last week - were really sore tonight. I don't want to lose momentum by taking a break, and I'm really disappointed because otherwise I felt the run went well. It was hard work but definitely not too much for me. I'm thinking I might need better shoes, or maybe insoles, or a knee strap...?? Any advice? Thanks.
