+\texttt{OnlySports Dataset}, a comprehensive collection of English sports documents. This dataset comprises a diverse range of content including news articles, blogs, match reports, interviews, and tutorials, all extracted from the FineWeb dataset. FineWeb is a thoroughly cleaned and deduplicated subset of CommonCrawl, spanning from 2013 to present. It represents one of the best open-source datasets for LLM training. Our extraction process involved two key steps: first, we applied URL filtering to identify potentially relevant content, and second, we developed a custom sports text classifier to accurately identify and extract sports-related documents from the filtered data. The resulting \texttt{OnlySports Dataset} encompasses 1.2 TB of text, equivalent to approximately 600 billion RWKV tokens. This makes it the largest sport domain dataset to date, significantly surpassing previous collections in both scale and comprehensiveness
