Finally managed to do an evening run in t-shirt and shorts and daylight. I went from Whaley Bridge up to the Bow Stones then dropped down into Lyme Park (used as Pemberley in the BBC's production of Pride and Prejudice).
The sun was setting as I ran around The Cage, back through a herd of deer and past Moorside hotel to Whaley managing to get back before darkness fell.
All in all a lovely spring evening run. How many people just sat and watched TV programmes they didn't really enjoy and won't remember while I was out in the magnificent Derbyshire countryside? If only they knew what they were missing.
