A bit late reporting but I did manage to complete w5r1 on Wednesday. The first 2 5 minutes runs were OK and perhaps not too surprising as they were also part of week 4. I was expecting to struggle with the third 5 minutes. Wasn't too bad at all - much to my surprise.
I have had some pain in my left knee over the last couple of days so won't be running today as originally planned but hopefully will see run 2 tomorrow.
Definitely seeing some benefits now. Not just in run duration either.
A few people say I look like I've lost weight. Although I haven't lost much I have certainly changed shape.
For me though the real change has been in heart rate. By the 3rd 60 second run of week 1 run 1 my heart rate was well over 160. It took me ages to recover back to a 'safe' rate after that session. On Wednesday it peaked at 157 after the third run but recovered below 140 well within the cool down session. So obviously there is real benefit coming from the programme.
After dreading the start of week 5 I find myself looking forwards to the challenge of run 2 - hopefully tomorrow.
Hope that you're all enjoying the Easter break
Best
John
