Colossal Vail 50/50 T-Shirt Unveiled

Thanks to the talented designers at Cirrus Visual Communications, we are excited to share the 2019 T-shirt for the Colossal Vail 50/50 presented by Fleet Feet Sports – Tucson. The image celebrates the rattlesnake mural that all participants will run through in the 50-Mile, 55K and Half-Marathon distances on November 9. Created by Ed Muren, this mural is the first art project to lively up the cement culverts the AZT utilizes to safely cross under roadways.

North Rim Ramble Results

The AZT North Rim Ramble presented by Summit Hut on August 25 was a huge success, with 82 runners finishing this annual event among the spruce and aspens of the Kaibab National Forest. A course record was set in the half-marathon when Mike Popejoy finished in 1:21:50. Laura Haley finished her very first marathon in 4:01:47, capturing the women’s marathon win and finishing third overall. Complete results can be found here. Thanks to all the runners and families who traveled great distances to participate in this trail running event for the benefit of the Arizona Trail Association. We hope you’ll join us next summer as the Ramble tradition continues…
