I may be slow (which certainly describes my running speed) but realised a couple of things on week 4 that didn't strike me until I did the first run last night.
ALL of the lead up weeks have you running overall for about the same amount of time - 8 mins and week 4 doubles that so the step up although not feeling massive - is huge
The other runs also give you the same or more recovery time than you have just run. Week 4 is half the recovery time.
Scary stuff when looked at in that way. But having done the week 4 run 1 last night I can just say, the preparation of the previous weeks is brilliant. Yes it was a step up, but not the leap that the figures suggest. So well done to all those getting through or past week 4!!!!!
See you in week 5 x
