Always a great event. Water is never predictable! Great challenge and well organized race.
Fun, well-attended race with handmade awards and artistic T-shirt designs. Race is held even in rough water conditions.

Each year it’s a bit different and always fun.

It was a blast! Well organized and lots of fun!!
