    A couple in their 60s has travelled 12,000 miles across 16 countries from Britain to China - riding their bikes all the way. Grandparents Peter and Chris stepped on the long journey after deciding to “do something a bit different”. They traversed (横穿) cities, deserts, mountains and everything in between across Europe, the Middle East and the East Asia.

Peter, 66, said the moment they finally had a look at the famous Great Wall after a year and a half of cycling 30 miles a day was “really exciting”. At the end of their journey, the special pair didn’t fly home but instead choose to book a cabin (舱) inside a 400m-long ship.

“You never know what the day is going to bring. All you know is that you are going to get on your bike and cycle. Every day is an adventure and every day is new. Overall, the experience is unbelievable, “ Peter said.

At first Peter and Chris set out to cycle from Britain in January 2017 but were forced home. They had cycled all the way to Hungary when Peter slipped and broke his leg. After seven months of recovery, the couple set out again in Britain. They finally arrived in China in November 2018.

Both Peter and Chris agreed that the best part of the entire trip was coming across the kindness of strangers along the way, many of whom invited the couple for food and drink. Chris, 64, said, “It was a wonderful experience, particularly wonderful because of the amazing people we met along the way.”
