There are quite a few people talking about getting into running on this site:

while a lot of them might not be doing the kind of running you folks are I bet they would really appreciate knowing about these tools.

I always use the McMillan Running Calculator for predictions. It combines a few of the tools that have been showing up here. I wrote about it at RTW last year.

So here is something that has always made me curious with these calculators. I am running a half-marry in a week and if I put in my time based on my ten mile race a couple weeks ago I get 2:11. If I put in my marathon time from June (and I was in better shape at that point), I get 2:31.

It seems like these calculators depend on a factor (runners world is something like t^1.06) to determine how much faster/slower you will run based on the decrease/increase in distance… That factor had to be figured out somehow (experimentally?) and I have always wondered if it is based on more finely tuned athletes who can haul ass in shorts distances and never bonk in long ones?

Anyways, as much as I want them to be, these have never been good predictors for me!

If this calculator proves correct I will be doing backflips in Chicago.
