Isle of Wight swim and run for Southampton hospital
Two Southampton men are attempting to swim to the Isle of Wight, run 96km (60 miles) around it and swim back to raise money for charity.
Martyn Kennaugh, 37, and Dave Savage, 39, swam three miles (5km) across the Solent on Monday before running 15 miles (24km).
They plan to run a further 30 miles (48km) on Tuesday.
They want to raise £25,000 for a pancreatic cancer diagnostic machine for Southampton General Hospital.
On Wednesday they plan to run another 15 miles and swim back to the UK mainland across one of the busiest shipping lanes in the world.
They will cross the finish line on their journey in Gosport.
Mr Kennaugh, whose father died from pancreatic cancer aged 63, said he thought it was important that the disease was spotted and treated early.
He only learnt to swim two years ago while Mr Savage is a former professional triathlete who went through a cancer scare last year but recovered.
