A group of Canadian soldiers and veterans, many of them struggling with post traumatic stress, have arrived in London after a gruelling six-day cycling ride from Paris.

They took part in an event put on by the British-based charity Help for Heroes, which gathered 300 riders from the United Kingdom, Canada and the U.S., including a number of amputees who lost limbs in Afghanistan and Iraq.

The entire group stopped at various battlefields in northern France, and received a huge welcome in London as they ended the ride at Horse Guards Parade.

Most of the Canadians took part under the sponsorship of the charity Wounded Warriors Canada.
