Half Mary time - based on mcmillan running calculator (Page 2)

agarose2000 - 2010-04-09 11:56 AM The Mcmillan calculators have been extensively examined on runners/marathoners forums.

They seem to work fairly well with the big IF you have put in the requisite mileage for the race distance.

The longer the race, the more the calculator "overpredicts" - apparently, the calculator works best (or was based) on runners who trained 70 miles per week of running. That's a lot of running.

When I ran 80+ miles per week, all the Mcmillan times from 5k to HM lined up perfectly. The marathon, however, was still an overconfident prediction.

For BT triathletes who are usually running under 25 (often under 20) miles per week, you really can't reliably use the Mcmillan calculator, or at best use it as a "best-case" scenario given perfect conditions and a flat/downhill course assist.
