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!

Want to participate in the 2027 100-mile swim? The 100-Mile Aqua Challenge is growing into our Miles in Motion challenge, a year-long community challenge with swim, walk, run, ride and group options. The 100-mile swim is still part of it, and registration opens December 1. Learn more and sign up HERE!

How far is a mile in the Y pool?

Pool length = 25 yards
Pool lap = 50 yards
1 mile = 35 laps or 70 lengths
1 mile = 1,750 yards
3,500 laps = 100 miles

If you are swimming in a meter-length pool (Echo Hollow or Amazon):

Pool length = 25 meters 
Pool lap = 50 meters 
1 mile = 1,600 meters or 32 laps 
3,200 laps = 100 miles

Note: Amazon Pool sometimes has lane lines set up as long-course, which is 50-meter lengths or 100-meter laps!
