Lee McKenzie presents live coverage of the first practice session for the weekend's Canadian Grand Prix. Canada holds the distinction of hosting the longest Grand Prix of all time - the 2011 race lasted 4h 4m 39.537s and included a two-hour rain delay. It was eventually won in dramatic style by Jenson Button.
In 2013, the first practice resembled those conditions, as British driver Paul di Resta battled the puddles, and his rivals, to post a session-leading time of 1:21.020. Fellow Briton Jenson Button was close behind him, with Frenchman Romain Grosjean in third.
