The Ultimate Ride personal watercraft challenge will take the team from London to New Zealand for charity
If successful, the five-month trip will break the world record for distance travelled on a PWC by 8000 miles.
The brave group is hoping to raise money for and awareness of cancer prevention, working with cancer organisations across the world.
Jeremy Burfoot, himself a cancer survivor, is leading the team through the waterways of Europe, around the Arabian Peninsula via the old Arab spice trade routes, down the western coast of India, via Singapore to their final destination of Auckland.
“This challenge is an epic adventure, which will include giant canal and river barges, along with storms, huge waves, sharks and whales, but hopefully not pirates!”
“We’ve had a good ride on the Rhine; conditions are pretty good, though the river is flooded in parts,” wrote Jeremy on his blog.
“It’s prime camping season now, being the German summer, so we’re having to slow down to avoid p***ing people off.”
“We’ve been through about 10 locks and we’re keen to get through as many as we can with a target of around 24. There’ll be 60 locks in total.”
