RE: More cycling stuff, less PC time...

Time is a really valuable asset. And scarse too. I've been experiencing the same as you; too much to do in way too few hours 😂

I checked my own chain and to my surprise it's already worn as well, just after about 1300km!

Chains also stretch out when you do more climbing, so your rides Germany probably 'helped' with that.
Good luck with the replacement!
