Ash completes training on the Great Wall before heading south for some language prep, and onto the source and the beginning of the mission.
Journey with record-breaking young explorer Ash Dykes on his epic world first to walk the entire length of Yangtze River.
Join Ash as he battles 4,000 kilometers of treacherous terrain, hundreds of encounters with local people, wildlife and the river itself to become the first person in recorded history to walk the entire length of the Yangtze River.
The river Yangtze, at 3,900 miles (6,300km), is the third longest in the world, behind the Nile and the Amazon, and the longest to flow through a single country.
Ash Dykes, from Old Colwyn, Conwy, began his journey at the source of the river on the Tibetan plateau and finished near Shanghai on Monday.
But his finish was delayed by two days after Shanghai was hit by Typhoon Lekima over the weekend.
Mr Dykes said his river walk would "go down in the history books".
He was greeted by well wishers and media outlets as he finished his trek
Mr Dykes said being the first to walk the entire length of the river has attracted a lot of attention in China, and has involved photo shoots with Adidas, GQ magazine and martial arts actor Jet Li.
"It's big news here. I've been doing a lot of TV and magazines. We've done an international and a China documentary," he said.
"I wasn't expecting a lot of this, it has blown up. My book is being translated into Mandarin and I feel it's just the beginning."He said at the start of his journey he wanted to raise awareness of the country's biodiversity and uncover a side to China westerners rarely see, as well as highlighting environmental issues.
But the trek has not been easy.
"The start was actually the most difficult," he said.
"I was at 5,100m (16,730ft) - so five times the height of Snowdon and the same height as Mt Everest base camp. We had a lot of people turning off through altitude sickness or injury," he said."There was a two-month delay to get started. When I finally got there it was starting to turn into winter, there were the first snowfalls and it was falling to -20C.
"The bears were coming down off the peaks of the mountains because it was too cold and they were hunting. We were just walking calories to them."
Mr Dykes said this journey had been his most difficult and he felt at his "most vulnerable" during his time on the Tibetan plateau, but said his adventures will get "more ambitious".
"This is only the beginning..."
