This year, we’re going back to prehistoric times, camping, parties, kids events, live music and bash celebrating the most delicious suds around made by Big Day Brewing. RIDE TOGETHER The magic of this race is the vibe. It’s about the encouragement from your fellow 500 riders. High fives, cheers, support from strangers, heartache, victory, and sore legs. It’s about perseverance, costumes, the music, the quiet riding at night, the beer, the party, bacon lap, the grilled cheese, the campground scene … come live the experience and become part of the history here at the Glen.
