The BBC has announced that it will continue its live radio coverage of horse racing until 2016.
Derek Thompson has joined the broadcaster's team for next month's Cheltenham Festival, the first event to fall under its new contract.
Gold Cup-winning jockey Andrew Thornton and Paralympian and broadcaster Kate Grey will also help cover the four days of racing from March 12 to 15.
"We're really looking forward to the Cheltenham Festival, when the whole station gets involved to bring all the action, atmosphere and excitement to listeners. I'm also delighted to welcome Andrew, Derek and Kate to our team," said Jonathan Wall, acting controller of BBC Radio 5 live and 5 live Sports Extra.
"The sport has always been a core part of BBC Radio 5 live's output and 2013 will see more great coverage led by the best commentary team in the business: Cornelius Lysaght and John Hunt.
"The comprehensive radio coverage combined with the wide reach of BBC online and mobile will deliver excellent coverage of the sport to audiences."
The new four-year deal will cover all major races at home and abroad.
