What this race demands

The Big Shoulders Swim requires sustained open-water endurance to complete a 5 km distance in Lake Michigan. Athletes must maintain pacing and sighting efficiency over an extended swimming duration.

Open-Water Endurance

The 5 km distance demands continuous cardiovascular output and muscular stamina without the benefit of wall pushes found in pool swimming.

Sighting and Pacing

Navigating Lake Michigan requires consistent bilateral breathing and open-water sighting skills to maintain a direct line over the extended duration.
