I Heart Hill Repeats?

I've been worried I might see smaller fitness gains this time around because I started out in better shape than I was in when I started training for Buffalo. But this morning I ran 8 hilly miles at 9:20 pace, which is a breakthrough of sorts. Today, for the first time EVER, I ran the full length of Sunset (beginning at Charlotte Street and ending at Old Toll Road) without stopping. There have been many, many times that I've made it almost to the top, but then that last little steep part forces me to walk. Not today. Today, I ran the entire thing feeling strong, which is a noticeable improvement in strength and fitness. After today, I'm even considering changing my attidtude about hill repeats:-).
