Two British rowers have been forced to postpone a world record attempt to cross the North Atlantic because of concerns about the number of icebergs.
- 44-year-old Roz Savage and 48-year-old Andrew Morris from Nottinghamshire were hoping to become the first mixed-sex team to make the 2,000 mile voyage
- It would take them from Newfoundland, in Canada to the Bristol Channel
- It would then go on to the River Thames to row into London ahead of the start of the 2012 Olympics
They have now been warned against going ahead with the challenge.
A collision with one of the bergs could prove catastrophic, risking capsizing the vessel in the icy waters or fracturing its hull.
The team plans to monitor the ice conditions this winter and may reschedule the expedition in 2013.
