It's what I'm doing, as someone who has never run i find it perfect, get your pace right, make sure you do your stretching before and after it really is amazing what you can achieve, you'll find once you get into it 90% is the mental battle. Omg I can't run for 90s, Omg I can't run for 3mins, Omg 5 fucking minutes, week 4 is the supposed big step up, but I promise you after each week you will be amazed at the thought's you had about the previous weeks running,
I hurt my knee on week 7 which is a 25min run ( I think) just before my knee problem I was feeling good and was going to run until I got to 5k, sadly I'm back at week 4 after about 6 weeks out.
Sorry for the long post, I can assure you starting the 5k will make you feel great about yourself, give it a go
