Well kind of, I have now completed W9R3! According to the RunKeeper app I downloaded I did 3.07k in 30 minutes, so still got a bit to go on that front, but I'll take my successes where I can!
I'm a bit dubious about the app though, when I did W9R2, it told me I did 2.33km in 30 minutes, which is slower than I can walk, and I know I can run faster than I can walk (because I know I can go much further running for 15 minutes and back than I can for walking 15 minutes and back). Google maps reckons I did 3.4 km in 30 minutes today, so I'm now slightly confused about how far I'm actually going! Clearly I need to get myself along a park run or something where they've got it measured better than I can!
In the grand scheme of things though, I'm happy that I can now run for 30 minutes
