I hiked a stretch of the Ice Age Trail, out and back. I actually did it in two sections. One in the morning, got lunch at a nearby cafe, and then figured I could finish that stretch. It makes me continuous through all of Dane County, Wisconsin. Part of it was on a gravel bike trail. That was so boring. There's another 20 miles of that going south, and I think I'll be running that. I can bike 8-10 miles down and then run back to my car.
I totally agree that pushing oneself makes that the new norm. Last year I was running three days a week. This is my third or fourth week doing four runs. It's harder, but I feel capable. It's partly an addiction and partly feeling like I'm more like myself. All my life I was a moderately capable distance runner trapped in an under motivated guy's body.
