Fun Fact: 104 minutes at world-record pace
At Kelvin Kiptum’s marathon world-record pace (2:00:35, Chicago 2023), a runner covers about 36.4 km in 104 minutes, roughly 86% of the full 42.195 km distance.

So if it’s good enough for elite athletes, it’s good enough for your high-focus work session, your intense learning block, or your creative flow. All you need is a reliable timer tool and the commitment to press start.
