The Challenge
2025: Run the Weekend
Philadelphia Marathon Weekend moves 35,000 runners through the city. Tucked inside that operation is a race for kids.
The Philadelphia Kid's Run is the weekend's most emotionally loaded one. For most of these kids, it's the first finish line they will ever cross. It also has to run inside a live marathon footprint, shared streets, shared security, shared medical — across two venues on three days, with parents and children who cannot be unaccounted for.
B-Side was hired to produce it in 2025. A year later, we were asked to do something harder: make it grow.
The Philadelphia City Fund brought B-Side on as executive producer for the Nemours Children's Health Philadelphia Kid's Run.
The Expo. Bib pickup and family programming inside the Pennsylvania Convention Center on Friday and Saturday.
The Oval. Saturday bib pickup and Sunday race morning on the Benjamin Franklin Parkway. Races by age group all staged back to back, each with its own start and its own crowd.
The Race Experience. Start and finish infrastructure at the Oval, a DJ running warm-ups and calling the day, mascots from Philadelphia's pro teams, course marshals, and medals hung on every kid who crossed.
Getting it Right
2026: The Second Ask
A children's race inside a marathon is a child-safety operation before it is anything else.
Every child was tied to an adult through a parent/child wristband system, with dynamic bib assignment so a family walking up at 7 a.m. on race morning got the same clean handoff as one that pre-registered in September. Dashes were staged by age group rather than run as one mass start, which kept each field small enough to see across.
Nothing about race logistics was improvised. Participant flow, staffing, and the full run of show cleared City operations, the primary race partner, security, and medical in advance — and held across all three days.
The 2026 weekend arrived with a different problem. Grow participation, sharpen the experience, and build something a sponsor would want to buy into for 2027, with no title sponsor underwriting the footprint in the meantime.
The instinct in that situation is to add. We went the other way.
Our guiding principle for 2026: do fewer things exceptionally well, measure all of it, and build a program strong enough that the next sponsor is buying into something proven rather than something promised.
Future Finishers Philadelphia
The race didn't need a new name. It needed a bigger house to live in. So B-Side built one, the Future Finishers Philadelphia is the program brand that now sits above the Philadelphia Kid's Run race, not a rebrand. The race keeps its name., everything else finally has somewhere to belong: the Expo zone, the Oval zone, the digital community, and a schools program that didn't exist before.
A journey, not a booth. At the Expo, kids pick up the bib, decorate it themselves with markers, stickers, and patches, then pose with it at a mini finish line. The bib they craft on Friday is the bib they wear across the real finish line on Sunday. Highest dwell time in the zone, lowest cost in the build.
The Oval, expanded. Registration and welcome, a Starting Line Promise wall where kids write why they run, a Kelly Drive training course that mirrors what real runners do, a cheer sign station, and a finish line photo moment where the medal goes up and the picture gets taken.
Off the Parkway. A 45-minute Future Finishers assembly piloting in Philadelphia-area elementary schools and rec centers in the weeks before race weekend, meeting kids where they already are, with registration tracked back by unique code.
Sponsor-ready by design. Every 2026 asset is built so a 2027 partner drops in without a reprint: a presented-by lockup on the bib, a logo on the backdrop, stickers in the bib shop. The brand equity we build this year carries forward. A sponsor enhances it. It doesn't replace it.
And because everything is measured — registrations, source, age distribution, repeat participation, zone traffic, social and media impressions — the 2027 conversation isn't "put your name on a kids' race." It's "become the presenting partner of a program with numbers."
Why It Worked
Restraint As Strategy.
Built To Be Shared
An Asset, Not An Event
Cutting the sprawl and investing in three strong Expo stations beat spreading a flat budget across eight weak ones.
A decorated bib in front of a branded backdrop is the photo a parent posts without being asked. That's the most valuable branding we produce.
PMW ends race weekend owning a program brand, a measurement baseline, and a schools pipeline — not just a completed race.
The Takeaway
Brand activations that have to feel premium, operate safely in someone else's venue, and stand up to repeat deployment. If you need an experience designed from concept through strike — and built to run again we would love to talk.
