Richard, brother Chris, and brother-in-law Gary Leeson were interviewed on the pitch at half-time, after completing the 40-mile ride from the King Power Stadium in Leicester to St. Andrew's.
Richard set up the text “ellis” campaign at the start of the 2013-14 season in an attempt to raise £100,000 to find a cure for MECP2 syndrome – a rare genetic disease that his son – Ellis - suffers from.
He is cycling to every Leicester City away game, a journey that has seen him cover over 2000 miles since August.
Last week, the campaign reached the halfway stage, with over £50,000 now raised.
Richard said: “It was great of Birmingham City to get us on the pitch at half time. It’s so important for getting the message about the campaign out there.
“Football League fans up and down the country have been so generous with their support and donations, and it’s incredibly heart-warming to see the money coming in from rival fans.”
Sky Bet, the title sponsor of the Football League, are backing Richard’s campaign throughout the season and arranged for the half time pitch appearance.
If you wish to make a donation text the word “MECP77” followed by £1, £2, £3, £5 or £10 to 70070.
