Or fall if you are in the southern hemisphere.

I did an extremely hilly 8 miler, last long run before the half marathon. DH was pre-riding his race course for next weekend and the road around the course was the perfect run site. It is about a four mile loop with just hill after hill. I was shocked I was able to keep my breathing and heart rate in check. Shockingly I am not sore yet either, I did stretch really well. The only complaint was I was exposed to 20 mph winds on an exposed roads but at least I had lovely views of Lake Travis to distract me.
