Joe Ogunmokun is a novice cyclist who has taken on the challenge to ride the equivalent distance of Wimbledon to Saint-Tropez in France (1377.6km), to raise money for his mentor, Ben Chatfield, who is dying of stage 4 glioblastoma multiforme.
Ben welcomed his first child, Ruby, to the world last year – but one month before she was born he was diagnosed with brain cancer.
The tumour is aggressive, and both chemotherapy and radiotherapy treatment have failed.
As a last resort, Ben's doctors have recommended a life-prolonging drug called Avastin, however, the medication costs £10,000 per treatment and this is needed every two weeks.
