Between 21 and 30 July 2008, The Extreme Cellists undertook their first international venture - the Four Peaks Challenge. This involved performances at the top of the tallest mountains in Scotland (Ben Nevis), England (Scafell Pike), Wales (Snowdon) and Ireland (Carrauntoohil) - a total of 4,445m (14,581ft) of climbing!

The challenge raised over £5,500 for two causes: Aspire, a charity who help rehabilitate people with spinal cord injuries, and Mountain Rescue (split between organisations in the four countries represented by the challenge).
