In the weeks before I got my last bout of 'flu, I didn't do much running. I told people that it was because I disliked running in dark, wet conditions, which was partly true; one evening, I got rather badly spooked running up a slope into pitch darkness. But a bigger part of the reason was that the joy had gone out of running for me.
Well, the joy is back. But conditions did have something to do with the lack of joy: it turns out that I enjoy running in Zernike Science Park a lot more than running in the Noorderplantsoen. This may seem strange, because the Noorderplantsoen is quite a nice park whereas the ZSP is a collection of parking lots encircled by streets that lead through a rather ghastly post-industrial business waste land. But for me as a runner, those mostly-flat, paved streets allow me to get a decent tempo going, and the trainer isn't tempted to make me do Fartlek-style interval training*) (up a slope, down another, 10 meters of running at top speed over gravel, and up another slope). While running uphill can be fun, I don't think Fartlek is on the whole my thing. Let me get some mileage under my feet and I'm happy as a pig in shit. So the next few trainings, I'm going to pick my group based on where they're going.
Of course, this only applies to running in the evening, with my club. It's different when I'm running alone, in the day - then, a quick dash into the Noorderplantsoen is convenient and fun.
*) What we do on those occasions isn't technically Fartlek, which as I read in the Wikipedia article actually does contain quite a bit of steady running. Maybe I should refer to those in-park interval exercises as Mini-Fartleks?
