The 1931 professional event saw victory by Australian Hubert Opperman with a sprint on the finish velodrome after his long solo breakaway was neutralized just outside Paris. Opperman's finishing time was a record 49 hours 21 minutes, despite constant rain. His diet included 12 pounds of celery, which he thought an important energy source (celery's energy content is minuscule, but it may have been a source of fluid and salt).
