$25K/second

Battle for the win in the Women's field at today's Boston Marathon came down to a spirited chase to close a big gap with the final difference being 3 seconds difference. Given the prize money for 1st is $150K and 2nd is $75K those 3 seconds were worth a lot than sweat & tears.

In the Men's race the battle for 1st wasn't a factor, though Ryan Hall who lead the field through the halfway mark could've surged a bit earlier utilizing that closing energy to capture 3rd; instead finishing 2 seconds out in 4th place - a $7500/sec penalty.
