Great Alaska Double Century

Overview

When the Fireweed 400 began, participants could only choose between 400 mile and century events. The scenery between the 100 mile turn around, and Valdez is too good to not be seen. The high mountain peaks of the Wrangell Mountains fill the horizon on your trip past the town of Glennallen. While climbing up Thompson Pass, the Worthington glacier is a welcome distraction. Finally, the run through Keystone Canyon along the thundering Lowe river and past Bridal Veil falls is nothing short of breathtaking. Inspired by this incredible scenery, Alaskan biker Pat Irwin helped create the Great Alaska Double Century. Bike all day, overnight in Valdez in a comfy hotel room or convivial campsite, and then return home either by road or on the Alaska Marine Highway ferry. Early race starts extend this incredible experience to riders who really want to savor their ride!

Often our biggest event, the 200 attracts about a hundred solo riders, and 400 more people on relays of 2 or 4 people. Over the years, tandem and tandem team entries have also participated in the Great Alaska Double Century.
