Karting Born in 2001 in
Poulton-le-Fylde, Smalley made his karting debut in 2011 at the Trent Valley Kart Club at the age of ten. Throughout his six-year karting campaign, he won titles such as the MSA E Plate
Rotax Junior series, and the 2016
Rotax Max Wintercup in the Rotax Max Junior class.
Ginetta Junior Championship Smalley made his car racing debut in the
2017 Ginetta Junior Championship, racing with
JHR Developments. In this year, he finished seventh in the standings, with a podium and a fastest lap. At the end of the year, he competed in the Winter Series at
Brands Hatch, winning the title with two wins and four podiums in the four races. Smalley continued in the series in
2018, this time switching teams to
Elite Motorsport. He dominated this year, winning eight races and picking up nine pole positions to win the title by eight points.
Ginetta GT5 Challenge In 2019, Smalley moved up to the
Ginetta GT5 Challenge, again with
Elite Motorsport. Winning two of the three races during the first round at
Oulton Park, he continued through the season with two further wins and ten podiums to finish second in the standings, 49 points behind champion Scott McKenna.
Ginetta GT4 Supercup In 2020, Smalley switched to the
Ginetta GT4 Supercup, competing with
Elite Motorsport. With four wins, he finished fourth in the standings with 462 points. Smalley continued in the championship in
2021, again with Elite Motorsport. Winning seven races and picking up 13 podiums, he won the title by 51 points.
Porsche Carrera Cup Great Britain In November 2021, it was announced that Smalley was the 2022-2023
Porsche Carrera Cup GB Junior Driver, following a shootout day earlier in the month. In the opening race of the season, he took his maiden win. He finished the season as runner-up, taking nine additional podiums besides his win. Smalley continued in the series for
2023 with Duckhams Yuasa Racing-affiliated
Team Parker Racing. The season started successfully as he claimed his maiden pole position at Donington Park. Although he fell to second in race one, which was held on a drying track, he moved up from fourth to first in the wet race two. His second win of the season came at Oulton Park. After qualifying third, he finished second in race one despite damage on the opening lap that affected the car's handling, but had a clean race two to finish on the top step of the podium and extend his championship lead. The second Donington Park round saw him take pole position, and even though he slipped down to third place in race one, he bounced back to win race two. With a second-place finish in race one at Silverstone, third place in race two was enough for Smalley to secure the championship title with one round still to go. Despite having the championship wrapped up, he still put on a strong performance in Brands Hatch to win the final race of the season. He finished with four wins and ten additional podiums and never finished below fourth position in a year that he described as "the best season of [his] life."
Porsche Supercup Smalley raced in the
Silverstone round of the
2022 Porsche Supercup as a guest driver, driving for
Duckhams Yuasa Racing with
CLRT, where he finished 12th. He also made a guest appearance in the
2023 edition with the same team. He stalled at the start of the race, but recovered well to regain 16 positions and finish 12th.
British GT Championship in 2024. Smalley joined Garage 59 for the
2024 British GT Championship, driving alongside
Shaun Balfe. Their first win came at Silverstone, where they timed their pit stops well and took advantage of incidents in front to move from fourth to the top step of the podium. The pair won the Silver-Am category, but only finished third in the overall standings.
GT World Challenge Europe in 2024. Smalley competed in the
2024 GT World Challenge Europe Endurance Cup with Garage 59. The team was not classified in the overall standings, but he finished 27th in the Bronze Cup alongside
Louis Prette, with a highlight being class pole position at the
24 Hours of Spa. In 2025, Smalley competed in the Gold Cup class of the
GT World Challenge Europe Sprint Cup with Garage 59. As part of this deal, he became a McLaren Junior Pro Driver. ==Karting record==
