Endurance Sports Media Group, LLC Launches, Announces Founding Partners
June 11, 2025

Carlsbad, CA. (June 11, 2025) /Endurance Sportswire/ – The founders of Perceev announce the launch of the Endurance Sports Media Group (ESMG), an industry collaboration to offer endemic advertising across all stages of the athlete’s journey. The Endurance Sports Media Group is the only curated ad serving network dedicated to endemic endurance sports publishers and advertisers.
ESMG’s goal is to showcase the power and reach of endurance sports through collaboration with the people and companies that make it all possible. Founding Partners include LetsRun.com, RunGuides, Run Tri Bike, and Perceev. Additional Founding Partners will be announced in the upcoming weeks.
“Digital publishers are the backbone of endurance sports. They power everything from race registration to results, content, and product discovery by focusing on what they do best. Advertising should be the foundation of sustainable revenue for these publishers, but finding the right brand partners is time-consuming and expensive. ESMG ensures collaboration with advertisers who value their audience,” said Ed Hoffman, founder of ESMG and Perceev.
“On the flip side, we see endemic brands advertising on non endemic platforms and they are not reaching their target audience,” adds Rebecca Hoffman, ESMG and Perceev co-founder. “ESMG is not a spray and pray platform. ESMG serves ads to a concentrated audience of endurance athletes of all levels – and at all stages of their journey.”
ESMG delivers high quality endemic ads that enhance the user experience and increase revenue for both publishers and brands.
“LetsRun.com has always been driven by authenticity and passion — from the fans to the athletes. We’re excited to be partnering with ESMG because it lets us stay focused on creating great content while giving brands a smarter, more authentic way to connect with our audience,” said Weldon Johnson, co-founder of LetsRun.com.
“We’re excited to be part of the Endurance Sports Media Group because it gives brands a simple way to scale, easily reaching endurance enthusiasts across multiple trusted platforms,” said Cory Jennermann, Managing Partner of RunGuides Media.
“I met Rebecca and Ed at TRE in 2024 and could feel their energy and passion about what they were doing with Perceev,” explains Jason Bahamundi, owner at Run Tri Bike. “In that discussion, I knew I wanted to have Run Tri Bike be a part of their platform and now we have that opportunity. The platform that they are bringing to publishers and endemic advertisers was needed…..now it is here and I am excited about it!”
With nearly 63 million ad impressions available per month from the Founding Partners and growing exponentially, ESMG is now reaching out to brands who need access to runners, cyclists and triathletes.
