Ryan will be cycling a whopping 80 miles (128km) tomorrow in aid of Prostate Cancer UK as part of his challenge to cycle to every Vanarama National League South club throughout the season.
Coming to the game tomorrow? Look out for him before the game where he'll be raising money for the charity on the day.
The ride will be one of the longest journeys Ryan will complete during the season as he prepares to set off from his home town of Crawley before he finishes his challenge on the 7th May at Bath City.

Everyone at Oxford City wishes Ryan good luck for his journey tomorrow!
