DUV Ultramarathon Statistics

The DUV (Deutsche Ultramarathon-Vereinigung) statistics site at https://statistik.d-u-v.org/ is the canonical database for ultramarathon results worldwide.

There is no official API. All data is served as HTML. Use curl / WebFetch and parse the returned pages.

Bad-parameter failure warning. Passing a value the backend doesn't recognise is not consistently handled. Depending on the endpoint and parameter, DUV may return a tiny Error - Invalid input: '<value>' page, return 0 rows, drop only that filter, or fall back to a broader result set up to a hard row cap (1000 rows on most endpoints, 4000 on getintbestlist.php). That's why exact tokens matter: a wrong-looking result is often a bad parameter, not a shortage of data. When in doubt, vary one parameter and watch the result count and page heading change.

Detailed references

Load these on demand — don't read them up front:

• references/parameters.md — shared value vocabularies (country/nation, distance, surface, year, gender, age category, IAU label). Read this whenever a query needs a filter beyond a plain id lookup.
• references/endpoints.md — per-endpoint parameters, example curl calls, and response shapes. Read the section for the endpoint you're about to call.

Core URL patterns

All endpoints are under https://statistik.d-u-v.org/. Every endpoint accepts language=EN|DE|FR|ES|IT|RU|ZH|JA — always pass language=EN for consistent parsing.
