I usually don't run too much outside in winter. I haven't previously picked out winter or early spring races to train for, so I more often go inside to the gym and use the treadmill.
That said I have a pair of running gloves, which I've never kept on all the way round a run, even 5k easy ones. I never wear a hat in winter - have never felt the need. I did buy an end-of-line reduced pair of really form fitting leggings for winter running, then found them so supportive for the muscles on long runs that I used them in the middle of summer too (not that we had a summer, but that's another forum). I can't run in public with them on though. I sweat, sorry, perspire too much for a long sleeved tight top, so have a loose one that keeps the wind off and I can push the sleeves up when I get too hot.
I do have a hi-viz gilet thing, from JJB like marshallini. Think it was a fiver. They're badly made and a poor fit, but cars can see you, and they've got pockets for putting the gloves in.
Maybe don't buy it all at once, Groundrush. As the evenings cool, discover what you need.
I can remember my school years, and cross country runs on wet ground in the freezing cold, wearing cotton t-shirt, shorts and y-fronts, socks and those dunlop daps. Ah, the good old days. Made me the runner I am today...
