Sounds like my commute home Monday. It was cloudy and drizzly, and I left work a little later than I'd hoped which made it darker for much more of the commute than usual. Cold, headwinds, front light starting to die out. And my bike shorts chamois was giving me lots of problems with the pad seam chaffing between my sit bone and the saddle. OUCH! The 15 mile commute took me a whole freakin' 90 minutes that time. It was miserable.
