Overview

A great race for trail runners or those looking for a new challenge, the Catalina Island Eco Half Marathon features gorgeous views of the Pacific Ocean, rugged terrain and lots of elevation change, which means it isn’t a race is for the PR-seeker.
The course begins in Avalon and begins to climb nearly right from the beginning. Runners will take Wrigley Terrace Road and climb nearly 400 feet before the second mile marker. The course will continue onto Renton Mine Road where a series of switchbacks will carry runners over the next few miles as the climb higher and higher.

At the 4.7 mile mark, runners will hit East Peak at 1,563 feet and will continue their climb until they topple out at over 1,600 feet. Once on East End Road, runners will hit that elevation high and then begin a short downhill section for less than a mile. The water station at the 6.2 mile marker will be the designation of another short climb followed by a descent to the 7.4 mile marker.

Course Description

The course climbs again at Memorial Road and runners will need to complete an out-and-back section along Divide Road. Once runners come to the Hermit Gulch Trail water station at mile 9.8, the rest of the course is truly downhill.
Over the next 3.2 miles, runners will descend 1,500 feet back to Avalon. This quad-burner finish is sure to test even the most seasoned runner, but will promise to be a fun way to fly through the final miles.
Awards will be given to the top 3 male and female overall finishers and well as the top 3 in each division. All finishers will receive a medal. This is a cupless event so runners will need to bring a bottle, pack, or container for their water.
