Hey Warren - WOW - you really are turning into a runner!!
Sounds like you had a good start, with great cadence through the whole event! Did you take any notice of your breathing during the last 5km?? I wonder if you had lost your control and this paved the way to the wheels slowly coming off?

Interested to hear your thoughts.
Look forward to you crushing these guys in K town for the PtoB.
Talk to you soon
Chris
