Hi all. This is my first post so apologies for any errors of protocol I'm 64 and only started C25K as, though I still work, I'm sedentary and developing a slight paunch. I'm not overweight and was going fine until W5. No until W5R2! I tried it last week and gave up 5 minutes into the second 8 Today I completed it but R3 seems like a huge jump. Did anyone else decide to just stick at this point? Just to keep fit?
