This is a trailer for a new four-part series available now for Friends of the Podcast. It's called Covering Team Sky and it's been written and read by Lionel Birnie.

Part one is called The Founding Principles and covers the period leading up to the launch of Team Sky in 2010. Part two is A Difficult Debut Season, focusing on the team's first year in the peloton. Part three, TUEs and The Jiffy Bag, looks at the 2011 Critérium du Dauphiné, won by Bradley Wiggins but which is now famous for the infamous delivery of a package to Team Sky's doctor on the race Richard Freeman. And part four looks at the 2012 season, when Wiggins became the first British rider to win the Tour de France, but when it also emerged that Dr Geert Leinders was working for the team. It was also a season when several members of staff left following the publication of the US Anti-Doping Agency's investigation into Lance Armstrong.
