Following the recent "ralking" (run/walking) chat I decided to give it a go after work tonight. I did a 2:1 of 2mins running and 1 min walking and I repeated this for 5.6k. Although no records were broken, my 5k time was about 43mins which was slightly quicker than a previous 5k run only on the same route! Not a bad time I suppose as I walked for the third of the time!
I certainly think I will do this again as I didn't feel too bad afterwards. Interested to hear from others who are trying this out.
