Just finished w3r1, and wasn't as bad as I'd thought. But...I should listen better to Sarah. After the first 3 min walk, I thought it was another 3 min run..blimey that went quick - only to be caught out when my anticipated 90s final run turned out to be a lot longer.. hey ho.
Did make me smile though with the advice about someone looking over a hedge shouldn't know whether you're running or walking - in my case there were times when they'd be lucky to know if I was moving 😂
Onwards and upwards !
