100-Mile Aqua Challenge

100-Mile Aqua Challenge

Challenge yourself to swim or aqua jog 100 miles in 2025!

Brought to you by your Y, City of Eugene Rec and Willamalane

The year-long challenge motivates individuals to stay active and reach for a long-term goal — the equivalent of swimming across the English Channel four times.

Participants will track their miles, yards or laps, and take part in a friendly competition. Swim or aqua jog in a pool, lake, ocean, river or whatever suits you. A mid-challenge party with take place at Amazon Pool during the summer and an end-of challenge party will happen at Willamalane during winter.

Users of the Y's pool must either be an active member or pay a day pass fee.
