Pace calculators

[Deleted User]

I have juts been calculating by various expecetd race times based on a recent(ish) race at

www.mcmillanrunning.com/

and my times are there or thereabouts.(half Mara is most recent time) I was just wondering how other people fared on these calculators?

5km 18:31;10km 38:28; 10mi 1:04:17;1/2 Mar 1:25:45; Mar 3:00:28
