Samuel and Connie were born a year apart, so they've always been close. Growing up they played together, explored the neighbourhood together... and fought cancer together.
Connie has fought cancer three times in her life and Samuel has been with her every step of the way. This time things are different. Connie is dying and she doesn't have much time left.
Faced with the fight of her life, she set Samuel the toughest challenge she could think of. It started as a joke in the kitchen. It turned into a promise.
The goal? To set a new Guinness World Record for the most distance travelled on a unicycle, raise $1 million and spread Connie's message of breast cancer awareness.
Samuel kept his promise to Connie and after travelling 15,955 kilometres over 364 days and raising nearly $1.5 million, on Thursday the 13th February 2014 he finished what was then the world's longest unicycle journey.
Not content to rest on their laurels Connie and Sam have set a new goal to raise $10 million dollars and we need your help.
