Thursday, April 6th at 6p
Two22 Run Club, 4550 S Reservoir Rd Centennial, CO 80015

Join your Colfax Marathon Ambassadors for a fun group training run at Two22 Brew! All abilities are welcome and there will be giveaways for those that attend.
Just maybe …. if you register for a Colfax race onsite, a Colfax Marathon Ambassador may buy you a drink 🙂
Denver-ites have a great appreciation of microbrewed beer. The Denver area also has great microbrews to appreciate. But, what’s missing is a microbrewery with a primarily locally active, socially conscious attitude. Two22 Brew’s mission is to provide beer-lovers with a way to give charitably to local causes through the beer they drink. They want the community to feel like they are a part of what they are doing, that they are more than just customers.
(And, yes, they have a dog-friendly patio. Only well-behaved, leashed dogs please!)
