Ran along Manly Beach for this. Thought I was doing ok until I turned back into the 20k Southerly blowing. It was hard work on the way back.
Total was 7.06ks in 29:21. Average pace of 4:09 per klm. Oops. A bit quick for marathon pace. Legs felt ok and breathing was pretty good too.
Not running Six Foot Ewen or spectating. Good luck with the race.
