kayaking circumnavigation of Britain earlier this year by Marcus Demuth. Amazingly he managed all 2,468 miles in just 80 days.
Co-coincidently when I opened the paper on the way to work yesterday I read about another circumnavigation of Britain planned for the new year, also by kayak, this time a tandem. The duo are raising money for the Motor Neurone Disease Association.
Even though they plan to use kites to speed their way, the projected completion time is higher, at 90 days. However unlike Marcus, who did his journey in May they will leave in February, when waters are cold and the storms fierce.
Good luck to them anyhow!
