The longest ice skating trial measures 8.5 km (5.26 miles) and it is the naturally frozen Winnipeg's Assiniboine Credit Union River Trail, at The Forks in Winnipeg, Manitoba, Canada, as measured on 26 January 2008.
The citizens of Winnipeg were happy to have a record based on the ice length due to the fact that Ottawa's neighbours and rivals had the record for the largest ice rink.
