Ten days ago we reported that the duo were in Wugu on the Yangtze River, just 450km away from completing their epic 292-day journey from Istanbul to Shanghai - and becoming the first people to navigate Asia's longest river from source to sea by kayak.
But as Shanghai Daily reports, the Irishmen have reached their destination in one piece, and received a rapturous welcome from the city's Irish community at the Bund yesterday morning.
Burns and Collins, from Derry and Limerick respectively, negotiated the final leg of their charity challenge in sea kayaks, battling rapids and avoiding dangerous wildlife such as bears and wolves.
And on arrival in Shanghai they paid tribute to the kindness and generosity of the Chinese people they met along the way.
"Chinese people were incredible for the whole journey as they offered help everywhere," said Burns. "The fishermen gave us tea when we were cold and gave us food when we were hungry. We were well looked after."
