Here's what I'm doing.... It's called Learn To Run.

Week 1: Walk 3 minutes / Run 1 minute
Week 2: Walk 3 minutes / Run 2 minutes
Week 3: Walk 2 minutes / Run 3 minutes
Week 4: Walk 2 minutes / Run 5 minutes
Week 5: Walk 2 minutes / Run 7 minutes
Week 6: Walk 2 minutes / Run 10 minutes
Week 7: Walk 1 minute / Run 14 minutes
Week 8: Walk 30 seconds (if you NEED to! If not, don't!) / Run 18 minutes

I'm on week 4 right now, although technically I've been doing it LONGER than 4 weeks. I just haven't been running 3 or 4 times per week like the program recommends... It says IF you do it that frequently, you won't have ANY problems moving up to the longer running time the next week. BUT I haven't been doing it frequently enough, so I usually DO have a hard time moving up.

That's why I thought this challenge would be good for me, since I could post EVERY day what I've done

Yesterday.... was my first day back in a while, so I ran 5 minutes walked 2 for the first 2.5 miles, then ran 3 walked 2 the rest of the way HOPEFULLY next time I'll be able to run 5 the whole way! BUT my knee is a little sore, so today is my strength training day and I MIGHT take tomorrow off depending on how that knee feels. Best-case scenario, I'll run again on Thursday. That's what I'm hoping for.
