Made in Chelsea stars Louise Thompson and Sam Thompson have joined forces with the British Heart Foundation to front its new MyMarathon challenge to help raise money for life saving heart research.

The brother and sister duo will take on the charity's new fundraising challenge, to run a marathon over the month of May, and will be competing to see who can finish first as they aim to raise vital funds in the fight against heart disease. Louise commented 'I'm delighted to support the British Heart Foundation's MyMarathon challenge and do my bit to help support their life saving research. We both know first-hand how devastating heart disease can be as our dad unfortunately had a heart attack many years ago'.
