i used to cycle a lot, and needed something cardio-ish to do at uni so decided to start running. i'm doing a six week running program i found online with a friend. Last week was four days/week run 5 min + walk 1 min x5 then two days just a 30 min walk.
This week it's run 8 min + walk 1 min x3 then run 3 min. It's going well so far, i'm happy with my progress, it's definitely improving! Starting to change my diet this week too, no more crappy foods, spring time has inspired me to make a change!
