My C25k journey has been long and turbulent (and also enjoyable when it's been going well). I actually started in September 2018 and was doing well. I got to the end of week 6 and then had to stop for surgery for my endometriosis at the end of November. I was hoping to start again after a couple of weeks but that was over ambitious. I had a couple of false starts and setbacks over the next few months where I'd get to week 4 or 5 but then be hit with illness or pain (from the endo) or motivation issues but finally got started again properly in July this year. I always knew it would take longer than 9 weeks for me because I really struggle with fatigue and pain and was more than happy to repeat weeks and take the course at a pace I was comfortable with.
Since July I have consistently been running 3 times a week with the very odd exception where I might have skipped the odd run. And I got to the start of week 9 at the end of September! Then I went to a festival and came back with festival flu which totally knocked me off my feet. Did a couple of runs which weren't brilliant but my breathing was still iffy from the lurgy so I wasn't overly surprised. I then had an endometriosis flare up which scuppered me again. I went out on Monday to do my first run for 12 days and it was awful! I thought I'd try a week 9 run to gauge where I was at and I did the 30 minutes but had to take a walking break 3 times during the run for about a minute at a time.
I'm due to go out again today after work and I'm not sure whether to keep on with the week 9 runs until they become a bit easier or to drop back a few weeks to a week with walking intervals and build up again.
