The 1954 Rugby League Challenge Cup final replay attracted 102,569 spectators.
The replay was contested by Warrington and Halifax at Odsal Stadium in Bradford. Warrington won 8–4, but the attendance became the defining statistic because it remains the largest recorded crowd for a rugby league match in Britain.
The original final had ended in a 4–4 draw at Wembley Stadium, forcing a replay. Odsal’s unusually large capacity and the importance of the rematch combined to produce the extraordinary crowd.
This figure is often described as rugby league’s all-time attendance record. It should not be confused with modern club-stadium capacities, which are generally much smaller and subject to stricter safety regulations.
