Run Fat Boy Run

I have come across an ideal running plan to get me started. it covers 6 miles and takes someone who is a poor runner into someone who can run for 30 minutes. This will be stage 1. The plan is

Week 1
Monday - run 1 min, walk 2 mins, repeat 10 times
Tuesday - rest
Wednesday - run 1 min, walk 1 min, repeat 10 times
Thursday - rest
Friday - rest
Saturday - run 1 min, walk 1 min, repeat 15 times
Sunday - rest

Week 2
Monday - run 2 mins, walk 2 mins, repeat 6 times
Tuesday - rest
Wednesday run 2 mins, walk 2 mins, repeat 10 times
Thursday - rest
Friday - rest
Saturday - run 2 mins, walk 1 min, repeat 10 times
Sunday - rest

Week 3
Monday - run 3 mins, walk 3 mins, repeat 5 times
Tuesday - rest
Wednesday - run 3 mins, walk 2 mins, repeat 6 times
Thursday - rest
Friday - rest
Saturday - run 5 mins, walk 1 min, repeat 10 times
Sunday - rest

Week 4
Monday - run 6 mins, walk 3 mins, repeat 4 times
Tuesday - rest
Wednesday - run 5 mins, walk 2 mins, repeat 4 times
Thursday - rest
Friday - rest
Saturday - run 8 mins, walk 3 mins, repeat 3 times
Sunday - rest

Week 5
Monday - run 8 mins, walk 2 mins, repeat 3 times
Tuesday - rest
Wednesday - run 10 minutes, walk 2 mins, repeat 2 times
Thursday - rest
Friday - rest
Saturday - run 20 minutes
Sunday - rest

Week 6
Monday - run 12 Min's, walk 2 Min's, repeat 2 times
Tuesday - rest
Wednesday - run 15 Min's, walk 2 Min's, repeat 2 times
Thursday - rest
Friday - rest
Saturday - run 30 minutes
Sunday - rest

All this effort to go from walking and being out of breath to being able to run 30 minutes will take combined just over 9 hours of my time over the next 6 weeks. Not much is it. It also means i can work in other exercises such as kettlebells without impacting on my time too much.
