Inspiration?

We talk a lot about running on this blog. But I haven't been running all that much lately. In fact, I ran more on my recent vacation on treadmills and over snow than I have since returning to Southern California--despite weather that should be encouraging (or at least less discouraging). My brand-new shoes are really nice, too... but other than the mud I got on them the other day, still sparkly white.

Any advice on getting out of the funk?
