I feel like I've been on the brink of this for quite a while having yoyo-ed between week 7 and 8 due to illness. I have a bit of trepidation but it's only 2 more minutes right!
The only thing is I don't really feel I'm progressing much in terms of distance.I've started running a different route, not the usual circular one I started out doing because as I run so early the circular route is very dark and lonely and I got scared! So now I run as far as I can to halfway then turn round and head back. I don't seem to be running any further though and I thought I might, especially as I've lost count of how many week 8 runs I've done now! Maybe there is a peak you reach and that's fine. I guess it's more being able to run for the time rather than the distance.
