If you ignore all the park runs, PB's and races, what is better for you health and fitness wise... A fast 5k for 30 mins or so, or that long slow run for an hour+ or perhaps some intervals ?
I have been doing all these types of runs and in each case my respiration and heart rate has been up, so that must be good.
My primary reason for running is health and fitness...but I've always wondered whether one type of running is better for you than another.
Yes, I'm also guilty for trying (not very well) to reduce my 5 or 10k times, but my longish slow run of 12k yesterday gave me the time to start thinking about this.
Happy fast or slow running
PS..New shoes great so far.
