100-Mile Aqua Challenge

100-Mile Aqua Challenge

Brought to you by your Y, City of Eugene Rec, Willamalane and River Road Park Recreation District

We're making waves together in 2026! We've challenged our community to swim or aquajog 100 miles—a distance equivalent to traveling from Vacouver, WA, to Cannon Beach, OR! Participants track their miles, yards or laps, and take part in a friendly competition, swimming or aqua jogging in a pool, lake, ocean, river or wherever!

Join us for the 2026 Challenge

Registration has been extended until May 1, 2026! Challenge yourself to swim and/or aquajog 100 miles in 2026—stay active and reach for the long-term goal of swimming the equivalent of crossing the English Channel 4 times. Participants will track miles online and those who share their progress on social media with the hashtag #100MilesThruWater will be entered to win cool swag.

Who: Anyone ages 12 and older
Cost: FREE! An optional event T-shirt can be added to your registration for $20
