Getting back into running after stopping in September, though I began winding down after my 10K race in July.
I hadn't meant to stop, and I wish I hadn't. Illness was a factor. But what I've found interesting is how much higher my baseline ability is compared to last year.
I've done a bit of reading on how quickly you lose fitness if you take a break from regular running, and was surprised at how slow it actually is. I don't have a specific link to hand but this is easily Googled.
But it's nice to have direct experience to back this up to. It's an encouragement to exercise, knowing that there's long-term value in it, even if you do choose to (or have to) take large breaks from time to time.
