Attention all Boston Marathon Racers!!!
Check out this spreadsheet for you\family on race day; very comprehensive.
A posting from the Runner's World Forum:
Boston Marathon pacing spreadsheet
Note: may take some time to load
The elevation profile page includes all the pacing information for every mile on the elevation chart (pace, total elapsed time, time of day), plus it shows your 5K and half marathon splits. If needed, this page can now be used as a spectator guide. Be sure to fully expand the page when you open it in order to see the required tabs at the bottom of the page.
