Victoria Pendleton, Training Dragons and the Science of Stars, plus the Inheritance Tracks of Russell T Davies

Adrian Chiles is joined by three hugely successful guests - all shining stars in their fields.

Victoria Pendleton won it all as a track cyclist, a quite astounding athlete who dug so deep, physically and mentally, in her career, and also in navigating her life after cycling.

Cressida Cowell is the writer and illustrator behind - amongst other things - the incredibly successful How to Train your Dragon series.

So we have a sports star, and a star author, and in Professor Dame Jocelyn Bell Burnell we have someone whose work enabled the discovery of a new kind of star, a discovery which changed astronomy forever.
