As they say here in Bavaria, "There is no such thing as bad weather, only bad clothing." That holds true for running gear too. I probably have more running gear than "the average bear" because of the weather. If I was still living in Southern California, I would just need shorts, singlets, one pair of lightweight tights, a couple of short-sleeved technical shirts and one long-sleeved shirt. If I spent my time in the gym on the treadmill instead of the great outdoors, I'd just need shorts and singlets. But I would much rather be outdoors and actually going somewhere. Because I run outdoors all year 'round, I have shorts and singlets for warm weather, capris, lightweight (spring/fall) tights, winter tights, long and short-sleeved technical shirts, fleece overshirts, ice spikes, and a Gore-Tex suit that doubles as a rain suit and winter running suit. Imelda Marcos may have spent her money on shoes, but I spend mine on running gear for all seasons.
It turns out that my best winter running gear comes from German grocery stores. I have gotten great bargains on technical shirts, tights, and fleece overshirts at the grocery store. In fact, my warmest winter tights are my 13 euro specials from the Aldi that I bought about 10 years ago. They're much warmer than tights that I ordered online that cost about four times as much.
We've had some crazy weather lately. Last Tuesday I set out on a run. There was a misty rain, which felt refreshing after the heat that we've been having. A few minutes into that run, the sky opened up and it started pouring. I was just dressed in shorts and a short-sleeved technical shirt. The shirt was loose, so at least it didn't stick to me. I hate the feeling of wet clothing sticking to me. My shorts, shoes, and socks were also soaking wet. I cut my run a little short to take a route that was less in the open. If I really wanted to, I could have brought a bar of soap and shampoo and had an outdoor shower. But I pressed on with the run and waited until I came home to have a shower. A couple of days later, it was hot and humid again. Who knows what it will be tomorrow. But no matter the weather, I am prepared for it.
