I successfully completed the couch to 5K last September and managed the whole 5K in 34 minutes. Let it lapse over the winter but started again in February and am up to week6. Tips I found that helped me.
If you find a week tough, do it again to help build up the stamina.
In the early weeks on runs 2 and 3 use some of the walking recovery time to keep jogging.
Look up the following weeks runs and see if you can incorporate part of that into your current runs. Especially useful when going from week 7 to 8. On week 7 run 1 do the 25 minutes on the second run do 26 the third 27. Then the transition to 28 minutes for week 8 is simple.
For info I am 62 and until last year hadn’t run for over 30 years and I was never very good then.
