Spring walk with the dog

My movement mostly consist of walking this guy! He keeps me moving on days I don't want to work out or push myself, I atleast get him out for a walk even if it is 20 mins! 

I want to do one of those 5km walk/run fun runs like with the foam or color packs this summer! So I tracked how long our usual longest path we walk is and it came to 2.35 km and we walked it in 35 mins!  So im going to start doubling when we have time with the goal in mind to be able to join in one of those fun 5k walks :) I'll start with walking this year and may running next year?
