Four servicemen, two of whom lost limbs in Afghanistan, are due to set off on a 50-day rowing challenge across the Atlantic Ocean.
An attempt by injured servicemen to row across the Atlantic has been delayed by poor weather.
Injured Cayle Royce and Scott Blaney will be joined by James Kayll and Mark Jenkins on the adventure from the Canary Islands to Antigua.
The four-man team, which includes two soldiers who lost limbs in Afghanistan, was due to start its 50-day challenge on Monday.
The group will split the rowing by doing two hours on and two hours off while living on freeze-dried food.
Organisers said weather conditions meant the race would now be delayed until Wednesday.
The team hope to finish the Talisker Whisky Atlantic Challenge in January.

Fingers amputated
Cayle Royce and Scott Blaney, injured by improvised explosive devices, are on the team with James Kayll and Mark Jenkins.
Cpl Blaney, from Nuneaton in Warwickshire, who serves with the Grenadier Guards, was wounded in an improvised explosive device (IED) blast in May 2007. It resulted in him having his right leg amputated above the knee.
They will split the rowing by doing two hours on and two hours off while living on freeze-dried food.
Trooper Royce, 27, from the Light Dragoons, lost both legs when he stepped on an IED just before he was picked up from an operation in May last year.
All fingers on his left hand were also partially amputated and he spent 10 weeks in hospital.
Cpt Mark Jenkins, 34, from Earlsfield, London, a physiotherapy officer with the Royal Army Medical Corps, met his team-mates while working at Headley Court rehabilitation centre between 2008 and 2010.
Leading the Row2Recovery team is 31-year-old Cpt James Kayll, from Blandford, Dorset. who began officer training at Sandhurst in May 2005 and has previously completed a rowing challenge in the Indian Ocean in April 2011.
They are attempting the challenge to raise money for the Help the Heroes charity for those injured in service.
Last year a six-man team raised £1m for wounded soldiers after completing the 3,000-mile (4,828km) feat in 51 days.
