About
Mt. Madonna Challenge is held on August 7, 2027, in Gilroy, Santa Clara County, California. The half marathon (13.1 mi) starts at 8:00 a.m., with the 10K (6.2 mi) and 5K (3.1 mi) at 8:30 a.m., on a course through forest and hill country.
Mount Madonna rises straight out of the Santa Clara valley, so a half marathon there is a climbing race whatever the surface — expect to lose ten to fifteen minutes on your road time and to gain it back only partly on the way down. Redwood cover keeps the temperature manageable, which matters in a Gilroy August, but the gradient does not care about the shade.
