Check out the slope (in feet/mile) of the BAA Half Marathon I ran today. Looking at the Elevational Profile before the race allowed me to plan for the upward sloping parts of Mile 7 and the killer Mile 11. The first mile, and it's negative slope, gave some a false sense of security about the course. The almost zero slope of Miles 4-6.5 made the race really "doable."
A beautiful day to be running in Boston and Brookline.
