well after a sleepless night worrying about today I did W4 R1 this morning and I am chuffed to bits because not only did I complete it but it wasn't half as bad as I thought it would be. If I am honest I found it easier than W3.
I think I finally found my pace today (dead slow!) but that's OK, if it means this can be achieved then that is good enough for me!!
So to all you approaching week 4 newbies, don't be worried and get our there and do it!!
