Compared to your Bronx pace, how much slower will your NYC Marathon pace be?

To predict, let's look at data from runners who ran the Bronx 10M and the NYC marathon in the same year. And see how their pace differed between the two races...

Made by George Murphy using data from NYRR.

Only runners with a Bronx pace slower than 6:00 and faster than 12:00 are shown.
Runners with a difference greater than 4 minutes were clamped back to 4mins.
