I am just starting to push my running distances- last year, a typical run for me would have been 7-11k. Now, my "window" is more like 10-17k. Today I broke 20km for the first time in a long time.
A friend at work is evangelising about Zone 2 running. She has previously done halves but is interested in marathon+ distances.
It got me thinking as I really enjoyed most of my slow 21k this morning and I wondered if anyone more experienced at distance running specifically practises Zone 2?
