@CanIKondo - how was your 20 minutes? W5R3 is The Best run of them all. Take it slow, much slower than you think you need to go, and then be MEGA PROUD of yourself when you've finished!
@fishfingersandketchup - I was similarly in my 40s, overweight and unfit when I started C25K. Have you finished Week 1 yet?
eatyourveg How's W6 for you? It's not uncommon for people to struggle going back to splits after the elation of the W5R3 20 minutes.
@PetraDelphiki I'd finish C25K first, before you start thinking about getting to 5K. Your pace naturally increases without any effort as you run more, so you don't know where you'll be by the time you finish Week 9.
Once running for 30 minutes, the Plus programe helps you extend to 35 minutes and to start thinking about pace in a structured way.
After that I stretched first to a 40 minute run. Then I aimed got a 45 minute run but got to 5K just under 43 minutes the first time.
Once I knew I could run the 5k I changed my focus to running 5K regardless of how long it took me. It was very quickly under 40 minutes without any conscious effort to speed up and within weeks under 35 minutes.
The only time I had to actively try to run faster (rather than increased pace coming as a natural consequence of running more effectively) was when pushing to get my 5k time from 32 minutes to under 30 minutes. That was months after finishing C25K.
