Just did the first podcast of Couch 2 5k, and I am sitting here drenched in perspiration (to put it nicely).
I only covered 2.43k's but at least I did it. Walked at 4km then shuffled (= run for me) at 5 and 5.5km's.
But, oh boy, my calf muscles are very sore, so maybe I should have stretched before hand.
I must try.....or..... ask my son if he could do something similar with the podcasts but with my music, I don't mind his voice except for when I told him to "get lost, I can't run anymore" but I did even if it was mainly shuffling :)
