Hamilton vows 'no holding back' in his 20th Formula One season

The 41-year-old Briton, who has won a record 105 Grand Prix, will line up this weekend where it all began for him in Melbourne with McLaren in 2007 for what will be his 381st race. The seven-time world champion failed to muster a single podium last year for the first time in his legendary career as he struggled to adapt to his new surroundings with the Scuderia. But he is entering the new season in a positive frame of mind, taking to Instagram this week to reflect on his long career in the sport.
