Did my first fast walk today since I started and finished C25K. I love walking but I just didn't have the legs during C25K on my rest days to walk anything other than a couple of slow miles.
So, a 5k walk in 42.5 minutes (only 5 minutes slower than my only 5k jog!). That would have taken me at least 5 minutes longer before C25K, so more evidence this plan has had a great impact on my fitness.
