From the USATF certified coach directory and USATF affiliated club rosters. USATF publishes credentialed coaches with level and event focus when reported by clubs. The roster JSON sources from these official datasets and merges them by city for directory builds.

Level 1 is the entry-level event coaching credential. Level 2 is the advanced event-specific credential, typically held by coaches with documented competitive experience and athlete development records at sectional, state, and national meet levels in sprinting.

Yes. Hurdle technique requires specialized coaching distinct from flat sprinting. The hurdleSpecialty field per row flags coaches who teach hurdle technique in addition to flat sprints, which helps hurdlers find appropriate technique-focused coaching options.

Each coach row carries a primary distance focus plus secondary distances when reported. The template surfaces the dominant distance for the city as a headline, with full distance breakdowns in a sidebar for sprinters focused on specific event development.

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 distance specialty signals match what serious sprinters and parents actually search.

Venues are sourced from USATF club facility listings plus public school and college track facilities. The trackVenueCount field per row flags cities with multiple venue options, which matters for year-round training and avoiding scheduling conflicts at single venues.

Yes. Each row supports a recentResults field that flags coaches with athletes at recent USATF Junior Olympics or USATF Outdoor Nationals in sprint events. The template renders that as a credibility callout, signaling competitive success alongside credential level.

USATF runs annual certification cycles. After each cycle, you merge new and re-certified coaches into the affected city rows and trigger a rebuild. Cities with newly promoted Level 2 coaches pick up credential upgrades, and unchanged cities stay served from cache.
