Two of the best distance runners on the planet. Same race, both fatigued, two very different pictures.
This freeze frame is deep into the 2026 London Marathon — Phil Sesemann working his way through the field with a very slight fade, Joshua Cheptegei fighting to hold form as he closes the race out.
Look at the front side.
Phil still has reach. Still has air. Still has time to complete the front side of the stride before he lands — because he’s getting the stride back underneath him at midstance, bracing exactly where he needs to, staying organised and balanced under fatigue.
Joshua is deeper into the fatigue picture. Slightly too much reach, not enough airtime to finish the front side shape, bracing a fraction early, fighting for stability on his right side.
And yet — he’s still getting on and off the ground with precision. Still finding the stretch-shortening cycle under that kind of fatigue. That’s remarkable. Any amateur runner in that state isn’t springing off the ground anymore — they’re pushing their way around the stride, muscling it, because the elastic system has nothing left to give.
That’s why Joshua is still running 3 min/km pace deep into a marathon while compromised. That’s the gap between world-class technique and everyone else — it’s not that fatigue doesn’t touch them. It’s what fatigue is allowed to take before the system breaks down.
Two of the greatest marathon runners alive, showing you what most of us can only dream of holding onto when it gets hard.
