Charity, you did a great job!!! Congratulations!!
I posted about my race in other places but forgot to come back to this thread! I ran the whole 10k, no walking, so I was really happy about that. I did it in 1:12:31, which is slow but was much better than I thought I would do. As for ranking, I was pretty much in the middle in my age group -- that includes people who just walked the whole thing, though. It was a great experience, and I'm definitely hooked. I signed up for a half marathon!
I'm running a 5k on April 21st and then another on May 12th, so that should be fun. I haven't done one yet, so it'll be different in terms of pacing and all that. Now that you're an old pro after your first 5k, I may be asking you for tips!
