Six marathon swimmers came together to tackle 48 miles of Lake Superior from Split Rock to Canal Park within 24 hours.

They came to shore around 8 a.m. this morning.

It’s the longest observed and documented swim in lake Superiors without wetsuits.

The relay team’s roster included: Karen Zemlin (55), Plymouth, MN; Seth Baetzold (28), Maplewood, MN; Michael Miller (57), Minneapolis, MN; Jeff Everett (62), Oakland, CA; Craig Collins (64), Minneapolis, MN; William “Casey” McGrath (51), Minneapolis, MN with David Cameron (46), Minneapolis, MN as an alternate swimmer. The team has more than 75 years of combined experience with competitive, solo, and relay swims on rivers, large lakes, and in the Pacific and Atlantic Oceans.

The group says this is both a celebration of the lake but also draws attention to its warming temps.
