In June 2005, Fiennes had to abandon an attempt to be the oldest Briton to climb Mount Everest when, in another climb for charity, he was forced to turn back as a result of heart problems, after reaching the final stopping point of the ascent. In March 2007, despite a lifelong fear of heights, Fiennes climbed the Eiger by its North Face, with sponsorship totalling £1.8 million to be paid to the Marie Curie Cancer Care Delivering Choice Programme. Kenton Cool first met Fiennes in 2004, and subsequently guided him in the Alps and Himalayas.
