The Capital Trail Coalition, an ambitious plan to connect more than 360 miles of local hiking and biking trails across the region, has a $500,000 funding grant from outdoor retailer REI. And now it's going to get support from a more unlikely source: Its own beer.

Rally Cry Session IPA, brewed and canned at Atlas Brew Works, will be released Sunday at REI's Uline flagship store, as well as stores and bars across the area. All proceeds will be donated to the Capital Trails Coalition through the Washington Area Bike Association, Atlas founder and CEO Justin Cox said in an email.

“Since the Capital Trails Coalition is all about outdoor activity, we decided to brew a style that would be a great, refreshing finish to a nice long bike ride, and thus the Session IPA was formed,” Cox said.

To keep costs down and raise more money for the project, the beer uses Falconers Flight and Cascade hops donated by DC Brau, Synergy Pilsen malt donated by Breiss, and cans donated by Can Source.

The Rally Cry launch party, which runs from 3 to 6 p.m., features indoor bike races, bike clinics and demonstrations, live music and, more importantly, two free Rally Crys per person. There's a second party Tuesday at the nearby Wunder Garten, beginning at 5:30 p.m. Six Atlas beers, including Rally Cry, will be on tap, and there will be music and food trucks.

“We thought it'd be an awesome opportunity to bring some attention to that project and mission while at the same time providing attendees with a special beer,” Cox said.

Rally Cry, which should sell for around $10 to $11, will be sold at selected Yes! Organic Markets, Glen's Garden Markets, and Union Kitchen Grocery stores, and at bars including DC Reynolds and Wonderland Ballroom. A full list of retailers is available on the Atlas Brew Works site.
