Does anyone ever do a slow run on purpose? My natural pace, even though exact speed varies a bit (& is probably slower than a lot if you), seems to be running at the limit of what I can do and still complete the run. I will feel pooped at the end, my breathing is tricky and heart rate up. I like the feeling of achievement after a run, but I cannot say I enjoy the act of running. I was wondering if I'd enjoy it more if I tried occasionally to really slow it down (not really sure how I'll force myself to slow). Will it adversely effect my running overall? Any advice on slow running?
