| Every
year the Grandfather Mountain Marathon's (GMM) reputation
as "America's Toughest" marathon attracts runners
from all over the country and many parts of the world.
The GMM has earned its tough reputation. The race
is 26.2 miles long, starting in Boone and ending on
the track at MacRae Meadows. The course features a
net elevation gain of 1,000 ft. However, runners who
successfully complete the race end up climbing well
over 3,000 ft. due to the rolling terrain of the course.
To make it even more difficult, the last portion of
the race-- a distance of 13 miles--is virtually uphill. |
