Welcome to the official Big A 50K Trail Race website!


The Big A 50K takes place every year, typically on the first Saturday in May.  The course is 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.


This year the event date will be on Saturday, May 5th, 2018 (May 6th heavy rain date) at 7:30, starting from the summit of Mount Agamenticus in York, ME.


A free cookout after the race is an important social part of the event and is an opportunity to relax with new and old friends, and enjoy the wonderful 360º views from the summit.  Participants are encouraged to bring an item for the aid station, as well as a side dish for the cookout.  The race organizers will be providing both carnivore and vegetarian food from the grill, salty snacks, and drinks.


NOTE: This is a limited field event and early registration is recommended. Click on REGISTER for details.


We hope to see you on race day!
