Big A 50K

used to be listed as the Mount Agameticus Challenge. Each year the week before mother’s Day. The Big A 50K takes place every year, typically on the first Saturday in May. The course is on single track and ATV trails in the Mount Agamenticus Conservation area with moderate to technical footing. In addition to providing a challenging trail running event, the race is also an important fundraiser for the trail construction and maintenance costs incurred by the Town of York for the trails surrounding Mount Agamenticus.
