Thanks! That's probably what I'll do. I'll aim for a 10k and then a half doing the run/walk for this winter. I've read a lot of mixed opinions about the run/walk, but it does make sense that it would help to avoid injuries- and that's kind of key for me. Also, I think if I get to the point where I can run/walk the half at a decent pace, I'll probably be able to actually run a full 5k. I have to say that I'm pleasantly surprised by how much I like running. I'm not very good at it, but this doesn't bother me the way it does when cycling. And, I'm finding that it does help me out when I actually do get on my bike.
