We had so much fun last year, we’re doing it again!



The annual 100 Acre Challenge is an obstacle 5K race set in the 100 Acre Wood in Intervale, NH. Competitors will run, swim, crawl, and climb as this 5K challenge takes them into the mud, water, over walls, rock piles and through the wood. It's all in fun and for a good cause with net proceeds benefiting the fundraising campaign for a new Outreach van for the Believe in Books Literacy Foundation. Individuals and teams of two or four are invited and for kids 12 and under there is the Mini Acre Challenge featuring mini obstacles.
