Well I did it! Have been repeating W1 as I hadn't managed to complete all three runs in their entirety first time round. W1R1(2) was just awful. Managed less than the W1R2(1). Today I managed the full 8 minutes of W1R2(2) without stopping. Woohoo! Admittedly it was possibly the slowest run ever completed by man or woman but I am awfully chuffed with myself!
