Aidan Murphy

Aidan Murphy is an Australian sprinter who has established himself as Australia’s greatest all-round sprinter across the traditional 100m, 200m and 400m distances. His personal bests of 10.23 (+1.1m/s), 19.88 (+1.7m/s) and 44.44 represent the strongest combination of performances ever recorded by an Australian across the three events, while his relay career has also produced Australian and Oceanian records.

Murphy first emerged nationally during the summer of 2021/22. Still only 18, he produced major personal bests across all three sprint distances, highlighted by a 20.41-second run (-1.3m/s) in Adelaide that broke the 37-year-old Australian U20 200m record. He went on to win the open 200m titles at both the Australian Championships and Oceania Championships, establishing himself as one of Australia’s outstanding junior all-round sprinters.

In 2022, that breakthrough launched Murphy onto the senior international stage. He qualified for the 200m at the World Athletics Championships in Eugene, making his Australian senior debut, before reaching the 200m semi-finals at the World Athletics U20 Championships in Cali two weeks later. He missed the final by one place and just 0.01 seconds, and also ran in two Australian U20 record-breaking 4x100m teams during the year.

Across 2023 and 2024, the transition from junior standout to established senior athlete was less straightforward. Murphy returned to the World Athletics Championships in Budapest in 2023, but his 200m progression stalled through the period. He placed third at the 2024 Australian Championships and second at the Oceania Championships in Suva, ultimately missing qualification for the Paris Olympic Games. Later that year he began training in Adelaide under Nik Hagicostas and increasingly incorporated the 400m into his racing program.

In 2025, the change began to show. Murphy lowered his 400m best to 46.24 in Adelaide before improving again to 45.97 later in the season, while returning to the national podium over 200m. He ran 20.52 (+0.6m/s) in the rounds at the Australian Championships before placing second in the final in 20.40 (+2.2m/s). At the World Athletics Relays, he produced a 44.65-second flying split as Australia ran 2:59.73 to qualify for the World Championships, missing the then 41-year-old Australian record by just 0.03 seconds.

His international season continued at the World University Games in Germany, where Murphy finished fifth in the 200m and helped Australia place fourth in the 4x100m relay in 38.89. He then contested his third World Athletics Championships in Tokyo, racing the 200m and men’s 4x400m relay. The relay team crossed the line in 2:58.00, faster than the existing Australian record, before being disqualified for an exchange-zone infringement.

The first five months of 2026 were astonishing. Murphy opened the year by running 45.12 for 400m in Adelaide to break Bruce Frayne’s 41-year-old South Australian record, before lowering it again to 44.81 five weeks later. He also ran 10.23 (+1.1m/s) for 100m, another South Australian record, demonstrating the exceptional range that was beginning to define his sprinting.

In March, Murphy won the Adelaide Invitational 200m in a meet-record 20.43 (-1.3m/s), defeating a field that included Diamond League champion Jacory Patterson. A month later at the Australian Championships in Sydney, he finally broke through over 200m, lowering his four-year-old legal personal best from 20.41 (-1.3m/s) to 19.88 (+1.7m/s) behind Gout Gout. The performance made him the second Australian in history to run a wind-legal sub-20-second 200m and moved him to second on the Australian all-time list.

The momentum continued at the World Athletics Relays in Gaborone. Murphy anchored Australia to 2:57.30 in the qualifying round before Luke van Ratingen, Reece Holder, Thomas Reynolds and Murphy stormed to bronze in the final. Their 2:55.20 set new Australian and Oceanian records, ranked as the sixth-fastest men’s 4x400m performance in history, and made Australia the fourth-fastest nation of all time. Murphy closed the race with a 43.79-second anchor split.

Later that month in Darwin, Murphy completed a remarkable Oceania sprint double. He won the 400m in 44.44, a championship record that moved him to second on the Australian all-time list and just 0.06 seconds outside Darren Clark’s long-standing national record. He then returned to win the 200m in another championship record of 20.05 (+0.6m/s), taking his career tally to four Oceania titles. Only Michael Johnson and LaShawn Merritt are known to have run faster legal marks in both the 200m and 400m while contesting rounds of both events at the same meet.

Murphy’s season concluded with his Commonwealth Games debut in Glasgow. After recovering from a hamstring injury in the lead-up to the Games, he received an automatic place in the 200m semi-finals under the Games’ new qualifying format, which allowed leading athletes to bypass the opening round. He competed in the semi-final and added another major championship to an international résumé that already included three World Athletics Championships and two World Athletics Relays campaigns.
