Cary Gray of St. Louis, Mo., set off on his epic journey on July 1, 2013 and has already spanned 11 countries: U.S., Canada, Mexico, Belize, Gutemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, and Colombia.
In Panama, Gray broke the Guinness World Record for Longest Unicycle Journey, which previously belonged to fellow American Lars Clausen, who unicycled 14,686.82 kilometres in a double crossing of the U.S. in 2002.
In the future, Gray has plans to cycle Europe, Northern Africa, and Asia, adding another 40,000 kilometres to his journey.
But for now, he's on his way north to Prince Rupert and beyond, to Alaska—if snow plows can keep the road clear.
