ABOUT THE DOOR COUNTY TRIATHLON
–
The Door County Peninsula is often referred to as the “Cape Cod of the Midwest.” This popular Midwestern tourist destination offers an abundance of lodging, dining, shopping and entertainment options. The sandy shorelines and majestic bluffs along Green Bay north of Sturgeon Bay provide an ideal setting for a triathlon.
