Watch: Travelling 126 miles on a swan pedalo

A Royal Navy veteran is leading a group of fundraisers on a 126-mile (203km) journey down the River Thames on a swan pedalo.

Alan Thornewill, who sought mental health support after leaving the military, is taking on the challenge in the hope of raising £5,000 for the Combat Stress and RNLI charities.

The group set off from Lechlade, Gloucestershire, and are travelling through Oxfordshire and Berkshire before reaching Teddington, London.
