I've made enjoying the outdoors at least about 2 hours a day a life long priority. It's just nice being outside in nature, good for my mental and physical health, and a big part of how I see myself (and others see me). Since I've had dog(s), it's also a shared time outside with them. I feel sorry for dogs that get only a couple 10 minute walks a day. Running has been my main outdoor activity, but I also enjoy (or have enjoyed in the past) other activities like cross country skiing, orienteering, mountain biking, hiking/walking, climbing, dog sports/play, and photography, bird watching, etc. I do all those sports/activities with the reward being the activity itself and being outdoors. Of course, for someone that prioritizes outdoors fun, it makes sense to live in a place that is awesome outside, so I moved to Alaska more than two decades ago.
I've at times run over 100 miles per week with no intention of racing at all. I've also been in probable 15:30 5K shape as a masters athlete (10 years ago) while not even bothering to race on a certified course, judging by the (then recent) times of the guys I was beating in the low-cost local cross country/trail series (can't be bothered to pay ~$50 for a road race when I can do races for ~$3). I still haven't recalibrated my mind to accepting masters racing as meaningful to me, so I've stepped away from racing recent years as I've dropped from contention for overall wins. But I'm still cranking out the miles, about 65-70 mpw and increasing, a few weeks removed from taking two weeks off for a weird, non-running knee injury.
(side note: I hadn't weighed myself in years until a recent doctor's visit, so 175lbs at 5'10" was a bit of a shock. It occurred to me that maybe my relative sloth isn't due to age, and that I might actually still be competitive if I weren't 25-35lbs over race weight. I'm considering actually start to train instead of just running with no goals like usual.)
