Mealin finished third in the Formula Ford Scholarship class last season with 12 podiums, including victories at Brands Hatch and Oulton Park. He was also awarded the 2014 'Dunlop Spirit Award' for his dedication to motorsport training and development throughout the season. At the beginning of the year, Mealin's talent was recognised by McLaren Applied Technologies Performance Academy, as he was invited to take part in a three-day course filled with educational workshops and physical training sessions, focusing on driver fitness, pre-race preparation, race performance and post-race review and recovery.
The 21-year-old began his motorsport career racing karts locally on the Isle of Man in late 2007, finishing second in the Honda Junior Championship in 2008, his first year of competitive racing. He continued his development in the Honda Senior category and he competed in the Le Mans 24 Hours kart race, finishing third in class in 2012.
Mealin also took his first steps in car racing in 2012, taking part in a select number of races in the 750 Motor Club Stock Hatch Championship and the European Late Model Series in Holland. Two wins at Venray and Lydden Hill were the highlight of a 2013 campaign in the Late Model V8 Supercup before Mealin progressed into the Formula Ford Championship of Great Britain for 2014.
A strong start to the 2015 season, in which he won two of the opening six races, set Mealin on the way to eighth in the standings.
