The Marathon World Record Was Set on Garmin's Cheapest Watch
Sabastian Sawe ran 1:59:30 in London — the first legal sub-two-hour marathon in history. On his wrist was not a fēnix 8 or a Forerunner 970, but a five-year-old entry-level Forerunner 55.
The Garmin that broke the marathon world record
On 26 April 2026, Sabastian Sawe ran the London Marathon in 1:59:30. That is the first sub-two-hour marathon ever run in legal race conditions, and it took a full 1 minute 5 seconds off the late Kelvin Kiptum's 2:00:35.
So what was on his wrist for the fastest marathon in human history? Not a fēnix 8. Not a Forerunner 970.
A Forerunner 55. Garmin's cheapest running watch, released in 2021, around $199 and built for beginners.
Why that isn't as strange as it sounds
When you're a professional at that level, you don't ask your watch what to do. You already know your splits, your fuelling and your pace targets to the second, and there is a team on the course telling you the rest.
What you need from a watch is elapsed time and current pace, delivered instantly and weighing nothing. Everything else is a distraction and a few extra grams.
Training Readiness doesn't help you at kilometre 35. Maps don't help on a closed course. A brighter AMOLED screen doesn't make you faster — it makes the watch heavier and shortens the battery.
One honest caveat
Not everyone agrees on the exact model. The race photography isn't sharp enough to be certain, and some people think it was a Forerunner 255 rather than a 55.
It doesn't change the point. Both are cheap, both are light, and neither is anywhere near the top of Garmin's range.
What this should actually change for you
Most people buy a Garmin the wrong way round: pick the most expensive one affordable, then work out what the features do. The world record holder went the other way — decide what you need mid-race, then carry exactly that.
You are not Sabastian Sawe, and that cuts both ways. You probably do benefit from things he doesn't need: Training Readiness when you're guessing whether to run today, a race predictor when you're picking a goal, sleep and recovery data when you're fitting training around a job.
But it kills the idea that a flagship makes you faster. The fastest man in history didn't need one. The honest question isn't "which is the best Garmin" — it's "which features will I actually use".
