2020 Catalina Marathon, 10k, 5k race has been postponed to August 29, 2020

New Date: 08/29/2020

The Run Catalina team, and our Island Partners, are working hard under these difficult conditions to provide as many opportunities to run and experience the beauty and challenge of Catalina Island under the current restraints. While we appreciate your disappointment in not running this past weekend, we are equally disappointed as a year of work, planning, and marketing has gone into this run by our staff and our partners on the island. As a small business and small staff who take pride in our events and the runner experience we provide, we are all looking forward to getting past this current state of uncertainty and being back to planning events for your enjoyment in the very near future.

The following are the four options for your deferral around the postponement of the 2020 Catalina Island Marathon.

These options will apply to all of the runs which were postponed, the marathon, 10K, 5K and kids runs

Here Are Your Options:

The Deferred date is August 29th, 2020.  All entries for the respective run will automatically be deferred if no action is taken.  If the marathon morning boat ticket was purchased this will be deferred also.  We expect to have a date confirmed by the end of the week. Please understand that this is a multi-party decision and we are working hard with all of the Island partners to firm up this date.

Transfer your 2020 entry to our virtual option. Run 26.2 miles; 10K; 5K; in a beautiful setting, post a photo of your run, along with your results (optional) to our open Catalina Island Marathon Virtual Run Facebook Group.  We will mail to you your shirt; finisher medal and if you run the marathon you will receive your year bar to keep your streak going. 

How to signup for this option?
Select ‘Switch to Virtual Race’ below. Next, login and or add your email to locate your registration and submit your transfer and submit. That’s it! From there, go on your run and share your experience through this Catalina Island Marathon Virtual Run Facebook Group

By selecting this option below, you are deferring your Catalina Island Marathon, 10k or 5k entry to either the Catalina Island Half Marathon, 10k or 5k on November 14th. We will reach out directly to understand which distance you'd like to defer to. Select this option and expect to hear from us directly in the coming days. 

Choose this option below by April 12th if you'd like to register for any of our 2021 Catalina Island Marathon events at 50% off. That would put the marathon at a cost of $65.00 and the 5K or 10K at $17.50, plus processing fees. Once selecting, expect to hear from us in the coming days with your 50% coupon. 


California's oldest trail marathon takes place on beautiful Catalina Island located off the coast of Los Angeles and surrounded by blue ocean, green hills and more beauty than you have ever run through.   Experience the Catalina Island Conservancy the way it was intended to be experienced, on foot, running, and noticing the history and beauty of the island.  This is a bucket list event that you will want to run year, after year, after year.
