Hey Zed, a belated congrats on this - great race. I should have read this more closely earlier - it seems as though you and I are very similar in terms of where we are at and what we need to focus on, ie improved run time.
I think you're probably slightly ahead of me in terms of ability and targets - I think if I achieved what you did at Sunny Coast this year I'll be a happy man. As you might have gathered from my race report, Hawaii 70.3 was a difficult race to draw any meaningful conclusions from as it's a particularly hard course.
Re your comment on standalone running times, my standalone marathon pace seems to be a reasonable proxy for my 70.3 run pace, if that's any help to you. I'm doing Brisbane marathon in a couple of months to get a gauge on how I'm tracking.
I know Matty (coach) has me on the right track with my running, so look forward to seeing some improvement there hopefully.
