Choosing what to wear is tricky though. I HATE being cold, so I was really tempted to overdress when temps dropped. Running builds up a lot of heat though. So before I knew it, I was miles from home and stuck in the middle of a "Strip Run"... I'm shirtless, carrying a mitten in each hand, tugging at the jacket tied around my waist, wishing I was in shorts.
I have fleece line leggings but quickly realized I do not need those very often!
One good tip I read was to add 20 degrees F to any temperature and dress for that. If it's 50, wear what you'd wear to stand around in the 70s. That's helped.
Here's where I think I'm at now. Sorry for everything being in fahrenheit.
60 and up: Shorts, tank top, sun hat (day) or headband (night)
Upper 50s: Thin cotton stocking cap instead of hat/headband
Upper 40s: Long sleeve shirt instead of short sleeve
Upper 30s: Leggings instead of shorts
Lower 30s: Gloves, fleece vest
20s: Moisturize face to keep the air from hurting, long sleeve shirt might be one of my "32 heat" protective layer technology shirts instead of a random cotton one from the drawer. maybe.
I haven't run in the teens yet. I think 21 F is my record.
The vest is great because it's got pockets for my phone and that really opens up my options for leggings, I can wear any of them. If I'm not wearing a vest I have two pairs of leggings with side pockets that I really had to search for and treasure. I had to find light colored leggings because I run in the dark and wanted to reduce my chances of getting hit by a car. So that's a lot of criteria: light color, side pocket, high rise, size tall.
A few weeks ago I was running in the early morning wearing my light gray ETHOS leggings, when I tripped and just beefed it on the concrete. Scraped up my hands, ripped the knee of my leggings, and ground some kind of street dirt into them that does not wash out. I mended the rip and they are still in the rotation.
I bought some fleece "convertible gloves" - you can flip them open to get to your fingers. I thought this was a great idea, but the fleece does nothing but make my hands sweaty. Even in the 20s. Running gloves have to be thin.
If the sun is down I round the temperatures down. 35 at night, I'm probably wearing my vest. 35 during the day, I'll think about it.
If the wind is blowing with all the strength Kansas has, I hate running. I'm not this aggressive. I'm doing this because I feel mental clarity. Wind ruins it.
I haven't needed to layer up or wear a thicker stocking cap.
That's where I'm at with cold winter running. I'm doing about 20-25 kilometers per week. Oh but still gaining weight, because fuck winter. I deserve my comfort foods.
