About
Join the challenge at The Big A 50K Course and conquer the summit of Mount Agamenticus not once, but multiple times! This adrenaline-fueled event features a 10.35-mile loop that dares you to scale Second Hill and Third Hill, all while enjoying the stunning scenery. Whether you're aiming to hit the 50K mark, with its hearty 5,787 feet of elevation gain, or just want to experience part of the course, the choice is yours—with finish lines at 10 or more miles. Expect the trail to test your agility with its technical terrain full of rocks and roots; trail running shoes are a must! And while you're pushing your limits, you're also supporting the Mount A Conservation Region—your recommended minimum $20 donation works wonders for this beautiful area.
