Ok had my first go this today and for not doing anything really before this I am happy.
I didnt do all 8 runs, missed 4, 6 and 7. but kept walking through.
Oddly this hasn't made me upset but stregthened my conviction to carry on. I did much better than I expected.
So rest day tomorrow, will go for a walk anyway but no running and back to it Wednesday.
I can see how it would be easier outside where you keep your own pace. Took me a bit to get used to increasing the pace on the treadmill. Depending on the weather may try it Wednesday.
