Bridie O'Donnell and I have known each other since our high school days. She has gone on to become a Doctor and a world record breaking professional cyclist.
Bridie has some great things to say here about elite sport, becoming motivated and staying healthy.
I'm grateful to be able to bring this conversation to you, because it's not someone I've just met, with me getting to know my subject as I interview them - this is me and someone I go way back with who happens to be a very interesting human being.
If there's anything Dr Bridie says in this podcast that really motivates you, I'm sure she'd love to hear about it - you can catch her on Twitter at @bridie_od.
Please enjoy this Skype conversation with the brilliant Dr Bridie O'Donnell.
