Magnus Gluteus Maximus

Magnus Gluteus Maximus

Magnus Gluteus Maximus is the VHTRC annual holiday 50 km trail event held from Hemlock Overlook Regional Park. The course is an out and back so participants may turn around at any point or complete any distance they choose. The race distance is 50 km with about 4,000 feet of total ascent and descent. Historic finishing rates tend to hover near 50 percent as many runners elect to stop before the full distance.

The route follows the Bull Run Occoquan Trail downstream to Fountainhead Regional Park and then out to the Do Loop. The BROT is blazed blue and the course is lightly marked; the event does not use the White Loop or the Fountainhead mountain bike trail and does not go upstream from Hemlock. Participants should not cross streams on concrete cylinders. A GPX file is provided for navigation.

There are four aid stations located roughly at miles 5, 11.5, 18.5, and 25; each is passed twice on the out and back. Aid stations provide water, Gatorade, soda and typical aid station provisions, but no disposable cups, so runners must carry a bottle or reusable cup. Aid stations have published closing times based on a minimal pace of about 20 minutes per mile.

Entry is open with a non refundable $20 fee that covers use of the lodge, restroom access, fully stocked aid stations and a catered after event meal and beverages. Parking at Hemlock can be tight; organizers will direct parking within the park campus and advise against using the nearby winery lot or marked hiker areas.

The event carries real risks. No medical personnel or medical supplies are provided on course; participants are responsible for their own health and emergency care. Organizers will attempt to summon local emergency responders if needed, but remote locations may delay care. Visit the organization's website for the most recent information.
