Leading up to the 2012 Summer Games, which begin July 27, Koivu ran through the London borough of Hillingdon, located in the northwestern region of greater London. On day 67 of the torch's journey from Greece to London, the four-time Olympian from Finland was forced to contend with temperatures above 30 degrees Celsius, or 86 degrees Fahrenheit.
"It was a really great experience, when you see the smiles and the excitement about the Games you really see how big the Olympic Games really are," Koivu told RDS. "It was a privilege to be there representing Finland. These opportunities don't come often. Hopefully one day I can do it again."
The torch started Tuesday with a trip on the London Underground and ended more than 10 hours and close to 43 miles later.
Koivu wasn't the only four-time Olympic hockey player to carry the torch Tuesday -- Angela Ruggiero, a four-time medalist for the United States women's team, ran through the London borough of Richmond upon Thames.
