Anadia, Portugal. With Team Wales he won a
gold medal in the
team pursuit at the
2024 British Cycling National Track Championships at the

Ross-On-Wye & Dist CC 25-mile time trial at
Monmouth, Wales, in July 2024, against 77 competitors. He won bronze medals in each of the men's points race, the men's

Luoyang, China, in August 2024. He was sick with an upset stomach for the Road World Junior Championship time trial in
Zurich, Switzerland, in September 2024, and placed 24th overall out of 66 riders.
Israel Premier Tech Academy (2025–present) He signed a two-year contract to ride for
Sylvan Adams's from the 2025 season. Academy Manager Tim Elverson said: “Time trialling is his passion; it’s also an area in which the team is really keen to improve. He’s also got an eye on Classics racing, and that’s a big area in which we can work together.” Tarling said: "I think as it’s my first year the races that I could best fit into would be the classic-type races .... I also think with TT background that I have that it could be used for shorter stage races with TTs to carry a possible GC contention." ==Personal life==
