HAT Run 50k
The HAT Run 50k is an ultramarathon event held in Havre de Grace, Maryland. The race takes place at 461 Quaker Bottom Rd and utilizes a variety of terrain types. Participants navigate a course consisting primarily of single-track trails, supplemented by sections of open fields, dirt roads, and some paved surfaces.
The route is designed with a specific structural layout:
- 50K (one starting loop of 3 miles followed by two loops of 14 miles)
The course includes approximately 4,400 feet of total elevation gain. A notable feature of the landscape is the presence of four stream crossings. The difficulty of these crossings varies based on current water levels, and participants may encounter water deep enough to result in wet feet.
Registration for the event typically opens in late November. The deadline for registration is set for mid-March, several days prior to the event date. The event also utilizes a volunteer program, with signups for support roles opening in early February. Visit the organization's website for the most recent information.
