The rule of thumb for people running marathons in the three hour range is that half marathon pace is about 20 seconds faster per mile than marathon pace. For people on this board who are familiar with what these differing paces feel like, Meza's pacing differential appears incredible.


Extrapolating.

The rule of thumb for people running marathons in the TWO hour range is that half marathon pace is about 14 seconds faster per mile than marathon pace.

Since the 1/2 WR is 58:18 than means any marathon time faster than 2:02:42 is suspect.


Nice deflection.


I guess that I didn't make my point clear.

My point wasn't that a human being can't run a marathon faster than their predicted time based on a half marathon, my point was that someone trying to run a fast time for them (or in this case an age group record) would not speed up and slow down like this. In fact, when most people run a slow split in a marathon, the next split is even slower and the next one even slower (ans so on) . . .

To the general public (and people like the Marathon Investigation guy), reading that someone had splits in the 6:50s and then sped up into the 6:20s does not seem out of the realm of possibility. However, these are different physiological zones (this was the reason for my comment about what half marathon pace and marathon pace feel like). It reminds me of an infamous cheater's favorite workout -- 5 Miles at 5K pace.
