15 Year Old Sam Ruthe Become Youngest Person Ever To Run A Sub-4 Mile 1

Sam Ruthe, a 15-year-old from New Zealand, just ran a 3:58.35 mile, becoming the youngest person in history to break the four-minute barrier. His record-setting run cements his status as one of the most promising young talents in middle-distance running.

What happened

  • Ruthe clocked 3:58.35 at Auckland’s Go Media Stadium, finishing just behind training partner Sam Tanner.
  • With New Zealand’s 800m champion Ethan Smolej pacing early, Ruthe hit the final lap at 2:58, right on track for history.
  • Tanner surged in the last 400m, with Ruthe clinging on, crossing just 0.06 seconds behind but shattering the record.

The bigger picture

  • The four-minute mile is a legendary benchmark, first broken by Roger Bannister in 1954.
  • Even elite runners rarely hit this mark as teenagers—Jakob Ingebrigtsen ran 3:58.07 at 16, and Cam Myers ran 3:55.44 at the same age.
  • Ruthe doing it at 15? That’s unprecedented.

By the numbers

  • 7:56.18 – Ruthe’s 3000m time, a world record for 15-year-olds.
  • 60km (37 miles) – His weekly training mileage, half of what Tanner logs.
  • 2028 vs. 2032 – His Olympics timeline: LA is possible, but Brisbane could be his prime moment.

Between the lines

Ruthe isn’t just a talented runner—he’s part of a running dynasty:

  • Parents Ben and Jess Ruthe were national-level athletes.
  • Grandparents Trevor and Rosemary Wright hold European and Commonwealth medals.
  • His younger sister Daisy (13) is already running a 5:08 mile.

What’s next

With steady training under coach Craig Kirkwood, Ruthe is on a trajectory that could lead to Olympic and World Championship success.

Bottom line: New Zealand has a rising star in Sam Ruthe, and he’s only getting started.
