Have felt slower this week on the nursery run - not sure whether it's been because of headwinds, legs, or drag somewhere on the bike - both the Nexus on the back and the dynohub on the front could do with a service, and I vaguely recall Nexus rollerbrakes can get draggy with time, but I really CBA to take a look right now.
Still haven't figured out clothing for this weather; I run hot and the run to nursery is mostly an uphill drag, so I tend to cook a bit - if not on the way, as soon as I get off the bike and have to herd toddlers inside. So far this week I've tried merino baselayer and old Aldi softshell - nice and warm but clammy (and is now a bit big); merino baselayer and merino zip-front sweater - breathes well but not windproof enough; baselayer, sweater, and windproof gilet - bit clammy; and baselayer, sweater, and windproof jacket - OK so long as it's unzipped on the climb.
