Within an hour’s drive from both Philadelphia and New York City, IRONMAN 70.3 Princeton takes place on grounds rich in history and sparkling with modern amenities.
The one-loop bike course will start and finish at Mercer County Park. You make your way from the suburban park setting to the rolling countryside, and through the horse farms of rural Monmouth County. Mile one through eight is relatively flat, with the bulk of the course a mixture of flat with some rolling hills.
