The Maine Summit Trek for Tree is a unique fundraising and community event hosted by Lost Valley and benefitting Tree Street Youth. The Maine Summit Trek for Tree creates an opportunity for the whole community to summit Lost Valley in Auburn, Maine as many times as possible in 4 hours! Together, we will see how many 4k Maine peaks can be climbed both collectively and individually. Bring your competitive spirit or just show up for some fun!

While the event is open for all, the Maine Summit Trek for Tree also offers an Endurance Hiking Challenge. 

From 11AM-3PM, Endurance Challengers will run, hike, and walk the Access Road of Lost Valley to reach the peak. Take the chair lift down or descend the same path. Repeat as many times as possible to gain the equivalent elevation of some of Maine’s biggest peaks. At only 1/2 a mile and 200’ of gain, give it a try, how many laps can you get? Whether you take on the challenge for 1 hour, or all 4, burn your legs and get your heart pumping, challenge yourself! 

Endurance Hikers are asked to pay a $25 registration fee, which supports the cost of the event and includes special event swag. Additionally, Endurance Hikers are invited to take on a fundraising challenge. Invite friends and family to sponsor your runs up the mountain, offering a dollar amount for each successful run! There is no minimum amount to fundraise, and all funds go to a good cause: supporting Tree Street Youth’s programming! If you fundraise $100 or more, then your $25 registration fee will be returned back to you! 

The day will wrap up with an Awards Celebration that includes recognition for most laps, most fundraised, and more.
