Orcas Island 100

07 Feb 2021 (Sun)


Join Orcas Island 100

Orcas is a special island. More rugged than Lopez yet less crowded than San Juan Island, it has struck a delicate balance between friendliness and frostiness, development and preservation, tourist dollars and priceless privacy – for the time being at least. The growth of tourism is a distinctly modern development and an inevitable consequence of Orcas’ refreshing get-away-from-it-all location.

With that said, the Orcas Island 100 Mile Ultra is the place to be, it is apart of the Rainshadow Running Series. Whether you’re a Rainshadow veteran, or brand new to our race series, we’re glad you’ve found us here!

With some of the most beautiful and challenging trail ultras throughout the Northwest, Rainshadow Races will leave you wondering: Why run anywhere else?
