The maps on the following pages are divided by
checkpoint to checkpoint segments to give runners a
general overview of each section of the 2019 course.
Additional maps show areas that might be confusing
on training runs if you don’t know the course well.
Because the length of the course segments vary
significantly, as does their primary orientation
(north/south versus east/west), the orientation and
scale of the maps vary as well. The scale and map
orientation are provided in the corner of each map.
The following symbols are used throughout all maps.
Detailed AC100 veteran tips, as well as driving
directions for you and your crew, can be found in the
AC100 Race Book. The AC100 Map Book is available
for download as well.
