With an early evening start at the Corps Security headquarters in Cowcross Street, London, the team took it in turns on a static rowing machine to row all through the night and all of the following day.

The team, which included Gary Broad, Rob Hill and Jason Taylor, were in full view of passers by throughout the gruelling event and £200 of the money raised resulted from public donations who dropped money into collection buckets on the street.

The money will be evenly split between the company’s chosen charity – the Royal Marines Charitable Trust Fund – and the individuals’ preferred charities which are the Birmingham Children’s Hospital, Cornwall Air Ambulance Trust and Mind.

Participant Gary Broad said: “We would like to take this opportunity to thank the general public, colleagues and business partners for their support and generosity. It was a really tough challenge but the camaraderie kept us going and we’re delighted with the total amount raised.”
