Mararun China Marathon Event Platform Scraper

Scrapes the Mararun platform (saas-user-gw.mararun.com) — the dominant Chinese marathon management SaaS used by major CAA-labeled and regional road races across China. Returns structured event data for all event editions hosted on the platform: name (Chinese + English), race date, city, province, registration windows, participant cap, organizer, CAA label (gold/silver/bronze), and AIMS certification status.

What it does

Mararun hosts dedicated sub-platforms for each race organizer, keyed by a hostKey slug (e.g. beijing-host, guangzhou-host). The platform's gateway API at saas-user-gw.mararun.com/v1/match/lists is publicly accessible without authentication. This actor calls the API for each known organizer and normalises the response into a flat dataset.

The actor ships with 13 verified hostKeys covering the major CAA-labeled marathons and prominent regional events:

City	Event	Notes
Beijing	Beijing Marathon	Oldest on platform; multiple editions
Guangzhou	Guangzhou Marathon	CAA Gold Label
Wuhan	Wuhan Marathon
Nanjing	Nanjing Marathon
Tianjin	Tianjin Marathon
Kunming	Kunming Marathon	SCO-branded
Nanchang	Nanchang Marathon
Xi'an	Xi'an City Wall Half Marathon
Nanning	Nanning Marathon	Southern China
Haikou	Haikou Beach Marathon
Yangzhou	Yangzhou Half Marathon	Bank of China flagship half
Xuzhou	Xuzhou Marathon
Huai'an	Huai'an Marathon

Usage notes

• No proxy required — the saas-user-gw.mararun.com API is fully open (no auth, no Cloudflare).
• Discovery limitation — the platform's global organizer catalog (cloud-gateway.mararun.com) requires OAuth. New events on the platform must be added to the KNOWN_HOST_KEYS list in the actor source.
• distances_offered — the list endpoint does not expose individual distance categories; fetching per-edition detail pages would require an additional API call per event. This field is left empty in the current version.
• total: 5000 — Mararun's API uses 5000 as a sentinel value for "many results". The actor uses pageSize=200, which covers all known event histories in a single call.
