From the Road Runners Club of America certified coach directory and the Pose Method International instructor list. Both organizations publish their credentialed coaches. The roster JSON merges those two sources and groups coaches by city for the directory build.

RRCA Level 1 is the entry-level running coach certification. Level 2 requires documented coaching experience and additional coursework. Level 2 coaches typically have multi-year coaching histories with athletes at half-marathon, marathon, and ultramarathon distance ranges.

Each coach row captures their primary gait analysis tools, which can include 2D video, slow-motion video, force plates, pressure mats, and wearable sensors. The template renders the tool list per city, signaling analysis depth and rigor levels.

Each city still gets a page. The template emphasizes the individual coach profile when the count is low. Sparse cities still rank for local intent because the credential and tool depth signals match what serious runners actually search for in form work.

Yes. Each row supports a workshops field that lists upcoming form clinics in the city. The template renders that as a sidebar block, which helps runners attend technique-focused events rather than only one-on-one private session bookings.

RRCA recertifies coaches every two years. Pose Method credentials follow their own cycle. After each refresh, you merge new and recertified coaches into the affected city rows and trigger a rebuild. Cities with new credentials pick up updates immediately.
