Jake Humphrey, Mapping Canal Towpaths, Online Dominatrix and the Inheritance Tracks of Justin Hawkins

Jake Humphrey is a High Performance broadcaster - he's spoken openly about his mental health and what drives him, and in his podcast and new book he uncovers what makes the likes of Sir Chris Hoy and Sarina Wiegman tick.

Madelaine Thomas has excelled in not one but two fields. Firstly as a dominatrix and then as a tech entrepreneur helping others protect their privacy.

Dr Uy Hoang, also has two strings to his bow. As an eminent epidemiologist he maps the path of diseases. As an enthusiast for waterways he’s single-handedly photographing thousands of miles of tow paths for Google. Never mind streetview...this is canalview.

Also today, the surfer waiting to hear if she’s bagged the world record for riding a bigger wave than any other woman ever - and the Inheritance Tracks of the catsuit wearing, falsetto singing, rockstar Justin Hawkins.
