McMillan Running Calculator
Has anyone noticed a change in relationship between race time predictions over different distances, some time over the past year or so?? I'm pretty sure that for a given time/distance, McMillan is now predicting faster times for shorter distances and slower times for longer ones. e.g. call me stato but I'm pretty sure that plugging in my 10k pb of 33:25 predicted 16:09 for 5k and 2:34x for the marathon last time I checked, but now the figures are 16:05 and 2:36:49.
McMillan was always my favourite race time predictor because it seemed to work fairly well for me over these distances, but I can't help thinking I'll start to struggle with maintaining the relationship going down the distances now. Also, as far as I recall the RW predictor seems to work in the opposite direction, which would make the respective predictions even more diverse now.
I could e-mail the site and find out I suppose, but anyone know anything about this? Has he had too many complaints from people missing their marathon "targets"?

Stato!
It's still reporting the same times as when I checked it (half to full) in October, so any potential change predates that. I wrote down both the half time I entered and the marathon time it produced.
I fully expect to still miss that target!
eee up Stato.
Have you tried using WAVA to predict your times (i.e. use you 10K WAVA % to predict your marathon time). Now that is harsh when it comes to converting to marathon times (at least at my age).
Phil, I don't know when any change occurred, but even 2 years ago I didn't match the 5k& 10k time my half suggested.
And this is despite being told and feeling myself that I'm shorter distance biased.
yet I'm coming out 10mile and HM as my best 2 pound per pound times!
Wow - I'm going to use this thread as proof that even though my missus often calls me an obsessed running geek, that I'm still relatively sane compared to many!....
