Fernando Alonso is expecting his 300th weekend of Formula One grand prix racing to be a challenging one.
Montreal's Canadian Grand Prix takes place on one of the more power-dependent circuits on the calendar, due to its long back-straight. McLaren has struggled for straight-line speed this year due to a combination of an underpowered Renault power unit and an underperforming aerodynamic package.
The race will see Alonso become the fourth man -- after Rubens Barichello, Michael Schumacher and Jenson Button -- to enter his 300th race, although if his car makes it to the grid on Sunday it will be his 298th start.
