PrincessV,
I feel your pain about the no buffer thing. I have been able to faithfully stick to my training plan, even on my beach vacation over Memorial Day weekend. So far, my longest training run has been 8.6 miles (this past weekend). I've done numerous 5ks this year, and I feel like I'm doing everything I possibly can to be successful (my definition of success is finishing without getting swept). All that said, I still have a very bad feeling that I'm going to be chased by the sweepers, maybe even caught by the sweepers. I'm still about a minute too slow most days (I was consistently under, but then the heat happened, and no matter what I do, I can't get my pace back down). I'm joining a women's training group next month that's an 8 week program, complete with weekly in person coaching. If they can't help me improve my time, I may be in real trouble.
