A four-time Invictus Games gold medal winner and former paratrooper is due to begin a charity endurance event dubbed the world's toughest rowing race today.
Jordan Beecher had a leg amputated while serving with the Parachute Regiment in Afghanistan.
He is part of the "row2recovery" team, which has taken part in the Talisker Whisky Atlantic Challenge previously.
They will be up against 24 others at the start of the 3,000-mile race.
The journey from La Gomera in the Canary Islands will finish in English Harbour in Antigua in the new year.
Carsten Horen Olsen, chief executive of Atlantic Campaigns which runs the race, said:
"This is the biggest and most global race to date and we're thrilled that teams from all over the world have travelled to La Gomera to take part in the world's toughest row.
"Year on year, we are bowled over by the records smashed, the dedication of the fleet and the incredible journey we're privileged to take part in as we follow and support all of our participants.
"With weather looking favourable this winter, we're looking forward to our biggest record-breaking race yet."
The first teams are expected to arrive in Antigua around the third week in January.
