Haha. One of my regrets in life is not taking fitness more seriously whilst in my 40s and 50s. I'm 62 now and have to put up with the inevitability of injuries.
But running has been a real benefit to be since I started, about four years ago. It can be hard, but it really does give that sense of achievement, going out and doing a nice long run, at a leisurely pace, in beautiful scenery, when your body is in good shape.
During COVID lockdown, I went out on a sunny afternoon and ran 24km. I was shattered after it. I didn't know how many kms constituted a half marathon. I was working it out during the run, armed with the knowledge that Parkruns were 5km, and just over three miles. I was determined to finish my first half marathon, and I accomplished it.
I agree with the quote above, about walking helping to take ones mind away from the day to day problems of life, and that running has the same effect. To leave the house on a nice day, all kitted up, with a plan for where to go, is a special feeling. The cares of the world (not that I really have too many) are left behind, and the rewards, an hour or whatever later, will be tired legs, a refreshed mind, a refreshing drink, a nice rest, and a warm feeling of accomplishment.
Give it a try. It might change your life.
