After growing up in
mountain bike racing, during which he won various downhill championships, LeDuc switched to
desert racing. In 1999 and 2000, he ran the
SCORE International Laughlin Desert Challenge and scored the
Baja 2000 Class 8 win during the latter. In 2002, he began short course off-road competition; at the age of 20, he was the youngest driver in active off-road competition at the time, which gave him the nickname "The Kid". LeDuc made his Pro 4 debut in 2008, winning three times in his first season. In 2009, he began racing in the
Lucas Oil Off Road Racing Series and
Traxxas TORC Series, finishing second in the latter's championship. the latter is a race between Pro 2 and Pro 4 trucks. He also won his second Challenge Cup. He debuted in the series at the 2013 finale in Las Vegas; he won his heat race but finished last in the final after being involved in an accident. Two years later, LeDuc returned to SST for the
Grand Prix of Long Beach and
X Games Austin 2015. He finished tenth in Long Beach after starting fourth. At the X Games, he set the second-fastest time in qualifying, followed by finishing runner-up in his heat and ninth in the main. In 2016, he ran the SST weekend at the Sand Sports Super Show; after finishing seventh in the Friday night race, he was involved in a crash in the Saturday heat race that resulted in Tyler McQuarrie flipping onto his roof, which was followed by placing on the podium in the feature in third. From 2014 to 2017, LeDuc won four consecutive LOORRS Pro 4 championships. The 2014 season saw him win 11 of 14 and receive LOORRS Driver of the Year honors; he also won the TORC World Championship Ring and AMSOIL Cup. In 2015, he set the LOORRS record for most Pro 4 wins in a row at ten and he ended the year with 12. LeDuc battled with
Carl Renezeder for the 2016 championship and the two finished the year tied in points, with LeDuc claiming the tiebreaker as his eight wins outweighed Rezender's two. The fifth title came as part of a five-win campaign. A sixth LOORRS Pro 4 title and fifth Challenge Cup came in 2019. Low entry numbers forced LOORRS to cancel the 2020 Pro 4 season, which prompted LeDuc to join the newly formed
Championship Off-Road series in the same class. He won five of ten races, including the final weekend at Crandon, and the COR championship for his seventh title in Pro 4. When he swept the COR weekend at ERX Motor Park in July, he scored his 100th career win. Shortly after his 100th race victory,
Chip Ganassi Racing signed LeDuc for the first
Extreme E season in 2021, sharing an electric SUV with fellow off-road racer and X Games athlete
Sara Price. ==Personal life==
