Sunburst Races presented by KeyBank, will once again kick off summer in The Bend! Race day is officially set for Saturday, May 30, 2026.

We are proud to offer events for all fitness levels, including a half marathon, 10K run, 5K run, and a 5K fitness walk. Strollers, joggers, wagons, and baby carriers are allowed in the 5K Fitness Walk only. No bikes, scooters, skates, rollerblades, or similar items are permitted in any event due to safety/trip hazards.

For kids who want to walk or run, the minimum age for participation in the 5K or 10K is 6 years of age (on race day) and the minimum age for participation in the half marathon is 10 years of age (on race day). All kids, ages 6 and up, who are participating must be registered.

All events start and finish at the Century Center. There will be a beer garden for those 21 and older (ID required) and a family fun zone with activities for our youngest Sunburst-ers.

All race proceeds and donations will continue to benefit Beacon Children's Hospital.

To grow our impact and reach even more children and families, we offer participant fundraising through RunSignup. There is no obligation to raise funds, but if you feel called to the mission, you have an opportunity to do so. With participants able to fundraise, we have the potential to make an incredible impact! With the tools that RunSignup provides, it's a simple and seamless process.

On June 3, We Run Together.

Global Running Day is our holiday! A celebration of the activity we love and the sport that brings our community together. We invite all runners and walkers to join us for this free event on Wednesday, June 3, to mark the occasion, set a goal, and cross the finish line. We encourage you to bring your family, friends, and neighbors. This year, we will also have an a la carte option to be chip-timed.

This year's event will be happening in-person at Central Park and will be a 5k distance on the beautiful Riverwalk! The race will begin at 7:00 PM. Packet pick-up will be at the Fleet Feet Mishawaka store (3522 Grape Road, Mishawaka, IN) on Tuesday, June 2, 2026 between 4:00 PM - 7:00 PM and day-of-packet-pickup will be available starting at 5:00 PM from the Bendix Pavilion at Central Park.

The Big Run Finisher Medals, Shirts, and Hats can be purchased in the event store.

The Big Run has partnered with Girls on the Run for this event and encourages participants, if able, to donate their registration fee to Girls on the Run. You can donate during your registration or click on the link below for Girls on the Run.

Help Us Give Back: Through our charitable arm, Do the Run Thing™, Fleet Feet has partnered with Girls on the Run and its SoleMates program so we can help more girls cross more finish lines. Why? Because everyone benefits when we support our kids.

Here are two ways you can help:

1. Become a Solemate! Solemates raise critical funds for Girls on the Run while completing a physical challenge. You don't need to be a star athlete to join—you only need to be a champion for the girls in their communities.

2. Donate to your local Girls on the Run council. Your donation will benefit Girls on the Run programs and participants in the Michiana community.
