Use register_url when users are ready to sign up — it links directly to registration
Default search returns races starting from today, sorted by date
Combine zipcode + radius for location-based search (US only)
Combine sport + distance to narrow results (e.g., sport=running&distance=half-marathon)
The total_results field shows how many results were returned on this page; use page to paginate
