Planning the Susan G. Komen 3-Day® takes months of collaboration and careful coordination. Each route is carefully designed to be safe, challenging and memorable while taking participants on an unforgettable journey of up to 60 miles toward a world without breast cancer. 

This year’s Komen 3-Day Series will travel through four beautiful destinations — the historic streets of Boston, the charming neighborhoods of Dallas/Fort Worth, the waterfront in San Diego and the scenic paths of Tampa Bay. While each route and city offers its own unique experience, every mile is carefully planned long before the Pink Bubble arrives in town.  

Planning the Route 

The route planning process of the three day, 60-mile walk is a year-round effort that requires collaboration between Komen staff, city officials, police departments, public works teams, chambers of commerce, visitor bureaus and other local partners.  

“We’re very lucky to have great relationships with every city that we’re in,” route planner Ethan P. said. “I really can’t thank the cities enough for what they do for us.” 

Planners aim for approximately 20 miles each day of the event while identifying parks and open spaces for pit stops and lunch, and ensuring major intersections are staffed by route safety.  

Scenic paths, local landmarks and iconic attractions help shape the 3-Day routes, but planning also includes adapting to changing conditions. Construction projects, road closures, local events and even parking availability can impact where 3-Day participants walk from year to year. 

“When one event’s over, we’re already looking at next year and how to make the route better,” Ethan said. “It could be the smallest things like there’s not enough parking at this one spot to we just think that this area is much prettier.” 

To help participants confidently navigate all 60 miles, the route planning team marks the course with pink arrows. They are placed along the route to keep participants moving in the right direction, along pit stops, to lunch and back on to the next portion of the day’s route. It is another behind-the-scenes detail that’s key to creating a safe, seamless 3-Day experience. 

It Takes a Village 

A successful 3-Day route also depends on the support of the communities that welcome the Pink Bubble each year. The 3-Day team spends several months doing outreach with local businesses, neighborhoods and community partners along the route.  

“The 3-Day coaches do an amazing job at helping us and making sure we’re reaching out to everybody around where we’re walking,” Ethan said. “The support we have received from Boston, Dallas/Fort Worth, San Diego and now Tampa Bay has been truly amazing. “ 

The community spirit is part of what makes every 3-Day so special. From businesses decorating storefronts with pink decorations and snack stations to cheering spectators lining the sidewalks, the encouragement participants receive throughout the weekend happens because of the in-depth preparation that leads up to every event season. 

Every City Has Its Own Feel 

Each 3-Day route is different and that is what makes each city so special. This year, San Diego participants can look forward to a couple of new pit stops that Ethan described as “absolutely stunning,” though he is keeping the details a surprise. 

Tampa Bay returns to the 3-Day in February 2027 for the first time since 2013, giving many participants the opportunity to experience an entirely new route featuring waterfront views, downtown streets and scenic trails. 

“It’s going to be a very pretty route that’s also really diverse,” Ethan said.  

Boston will feature a new pier on Day 3 that participants will be able to walk around, while Dallas/Fort Worth’s new hotel and camp location has inspired thoughtful route updates that still preserve many of the familiar sights participants know and love.
