Strategic paid digital marketing drives record registration, leading to early sellout

Madison, WI (September 17, 2025) /ENDURANCE SPORTSWIRE/  — BibRave, a marketing agency specializing in fitness and endurance sports, is proud to announce that the 2025 Sleeping Bear Marathon, Half Marathon, and 5K have officially sold out, with all distances reaching capacity more than a month before race day on October 4. The sellout marks a major milestone for this iconic Michigan event.

BibRave worked with Race Day Events, the production company behind the Sleeping Bear Marathon, to deliver a full-scale digital marketing campaign spanning organic social media, email marketing, and paid social advertising. Over eight months, the campaign drove tens of thousands of clicks and impressions, with paid social delivering a 7X return on ad spend (ROAS) and generating over 11% of total registrations.

“We’re thrilled to see the Sleeping Bear Marathon generate such strong excitement and fill all its races well ahead of race day,” said Andy Wallace, Senior Vice President at BibRave. “This milestone reflects the powerful synergy between Race Day Events’ exceptional race experience and BibRave’s data-driven marketing strategies. It’s been incredibly rewarding to help bring more runners to this iconic event.”

The Sleeping Bear Marathon, Half Marathon, and 5K showcase the natural beauty of northern Michigan’s Sleeping Bear Dunes National Lakeshore, offering runners a scenic and memorable race experience. With a renewed surge in interest and an early sellout, the event is poised for a vibrant and successful 2025 edition.

“Partnering with BibRave has been instrumental in taking the Sleeping Bear Marathon to new heights,” said Ryan Griessmeyer, President of Race Day Events. “Their expertise in digital marketing and paid social campaigns helped us reach new audiences and re-engage our loyal community, resulting in a complete sellout. We couldn’t be happier with the results.”
