While modern GPS technology allows us to measure top speeds more accurately than ever before, comparing players across different eras remains a challenge.
This list ranks the 10 fastest rugby union (15-a-side) players of all time, taking into account recorded speed data, acceleration, match performances, and the reputation each player earned throughout their career.
From modern speed machines like Louis Rees-Zammit to legends such as Jonah Lomu, Christian Cullen and Jason Robinson, these are the players who left defenders chasing shadows.

Top 10 Fastest Rugby Union Players of All Time
10. Joe Rokocoko
One of the most explosive finishers of the professional era, Rokocoko combined genuine pace with exceptional power. Defenders often struggled to judge his speed because he was so effective at accelerating through contact and maintaining momentum. He scored 46 tries in 68 Tests for New Zealand, a remarkable strike rate that reflected how dangerous he was whenever he found space.
Extra fact: He was a key member of the dominant All Blacks side of the mid-2000s and remains one of New Zealand’s greatest wings.
9. Rupeni Caucaunibuca
Naturally gifted to a level rarely seen in rugby, Caucaunibuca possessed breathtaking speed and balance. At his best, he could leave defenders standing still and score tries from seemingly impossible situations. Many players who faced him regarded him as one of the most naturally talented backs the game has ever produced.
Extra fact: He was twice the top try scorer in the French Top 14 despite not always being known for his training discipline.
8. Jonny May
May brought track-athlete speed into modern Test rugby and consistently ranked among the fastest players recorded by GPS. His support lines, anticipation and relentless work rate allowed him to use that pace more effectively than many players with similar top-end speed. For much of the 2010s and early 2020s, he was England’s premier strike runner.
Extra fact: He became one of England’s highest-ever try scorers, proving he had much more than just raw pace.
7. Jonah Lomu
Lomu’s inclusion isn’t simply about speed—it’s about speed relative to size. At around 120–125 kg, he moved at a pace that most international wings weighing 30 kg less could barely match. His devastating performances at the 1995 Rugby World Cup changed the sport forever and redefined what a winger could look like.
Extra fact: His four-try demolition of England in the 1995 World Cup semi-final remains one of rugby’s most iconic performances.
6. Cheslin Kolbe
Kolbe may not possess the highest measured top speed on this list, but few players have ever accelerated as quickly. His footwork, balance and ability to change direction at full pace make him one of the most elusive runners rugby has seen. He has repeatedly produced game-changing moments on the biggest stages.
Extra fact: He played a crucial role in South Africa’s Rugby World Cup victories in both 2019 and 2023.
