My break in running lasted about ten years. I spent (and still spend) no time at all in gyms. I suppose I have had fitness somewhat thrust upon me as I am not a car driver, so it is cycle or shanks mare if I want to get anywhere.
Nonetheless, as soon as I got walking without sticks again, I started "running". Which means walking/running/walking, but getting outside and doing it.
And I find it absolutely intoxicating.
But like KK, although I may get out there four or even five times a week, I don't do training. I don't even own a watch yet, although Venom has kindly offered to do something about that. The T word makes me uneasy, unhappy, humiliated and ashamed. I'm not ever going to run fast, but I'm going to be able to run long and love it.
What are your aims? It does not at all follow that they should be the same as mine, but the answer to your questions depends on your dreams.
Above all enjoy it.
