I'm on Week 5 Day 2 of the C25K program. This week seems somewhat daunting with the increase of 5 min. to 8 min. to 20 min. of straight jogging/running. I read here this plan was developed in the 90's. I know it's still doable, but I was wondering what you had learned that perhaps makes your program more doable or better. I noticed yours has shorter run times with alternating walking breaks. Do you find people respond better to that sort of training. Just curious, because I do want to try to make running a part of my long term health. I'm willing to switch over to your schedule if it's more successful. At this point, I don't like running (gasp), but I know it's good for me. Thanks for any info.
