LISBON, PORTUGAL – The world of distance running is reeling after Jacob Kiplimo’s stunning performance at the Lisbon Half Marathon on March 8, 2026, setting a fresh world record of 57 minutes and 20 seconds. The time, averaging a blistering 2:43 per kilometer, has left even elite athletes in awe, prompting questions about the boundaries of human endurance. Czech Republic’s leading half marathoner, Patrik Vebr, weighed in on the remarkable feat, calling it “completely beyond human comprehension.”
Vebr, a consistent top finisher for the Czech Republic at the prestigious Prague Half Marathon for the past three years, acknowledged the sheer speed of Kiplimo’s run. “He could even run it faster,” Vebr told Aktuálně.cz. “He ran 56:42 last year, but it wasn’t recognized because he was running too close to the team car. Now he has the record at 57:20, but he’s capable of running that distance 40 seconds quicker.”
The implications of Kiplimo’s performance extend beyond simply a new record. It challenges conventional understanding of what’s physiologically possible in the half marathon distance. For many, the idea of sustaining a pace of 2:43 per kilometer for 21.1 kilometers feels almost unattainable. Vebr highlighted the difference in training backgrounds, noting that Kiplimo, like former marathon world record holder Eliud Kipchoge, transitioned from shorter, faster distances. “They have a huge speed reserve from running shorter races – 1500m or 5000m – where the pace is much quicker. They can run the last kilometer of a race at 2:20. So, that pace for a half marathon is a faster run for them, but not a sprint.”
The location of the record-breaking run – Lisbon – as well surprised Vebr. He explained that the coastal course, often affected by wind, doesn’t typically produce exceptionally prompt times. “Sometimes, elite runners run subpar times there. It’s along the coast, and the wind plays a big role. I was more surprised by that than the time itself. But this year, there were amazing performances across the board.”
The ability to maintain such a relentless pace, Vebr explained, isn’t just about aerobic capacity. It requires a combination of high-end speed and the ability to sustain it over a prolonged period. “You need to have run a lot of kilometers, you need an aerobic base. But without the speed, you can’t connect those two things.”
For the average runner, even attempting to match Kiplimo’s kilometer pace is unrealistic. “Most runners can’t even run a single kilometer that fast,” Vebr conceded with a smile. “And if one kilometer… I don’t think most runners could run 400 meters at that pace.”
Vebr, who holds a personal best of 63:24 in the half marathon (approximately a 3:00 per kilometer pace), is aiming to break the Czech national record, currently held by Jan Pešava at 61:31, a mark that has stood for over 28 years. He believes a sub-61 minute time is within reach, but acknowledges the widening gap between the world’s best and the European elite. “Currently, yes, but I’m expecting a significant surge in half marathon times in the Czech Republic. Damián Vích, who ran a great 10k, Martin Zajíc, the new record holder in the road 10k, and Honza Friš, who has long excelled at the 1500m, are all preparing. I hope we can all push each other towards faster times and compete with the broader European frontrunners.”
The current European record, held by Sweden’s Andreas Almgren at 58:41, demonstrates that European runners are closing the gap. Almgren’s path, starting with 800m and progressing through 1500m, 3000m, and 5000m before focusing on longer distances, mirrors the trajectory of Kiplimo, and Kipchoge.
Maintaining a consistent pace throughout the race is crucial for elite runners, but a “negative split” – running the second half faster than the first – is becoming increasingly common. “That means you run the first half a few seconds slower than the second, and you speed up in the final kilometers,” Vebr explained.
When pushing the body to its absolute limit, Vebr described a surprising phenomenon: a sense of euphoria. “When you’re well-prepared, like Kiplimo undoubtedly was, you actually enjoy the race. Where it should hurt the most – around the 16th or 17th kilometer in a half marathon – you feel a sense of euphoria. You know you’re going to make it. He broke the world record by ten seconds, and he knew he wouldn’t ease up by three seconds per kilometer. Euphoria kicks in, you don’t feel the pain as much, and it’s not such a fight for survival.”
Looking ahead, Vebr’s immediate focus isn’t on a specific half marathon, but his long-term goal is to break the 61-minute barrier. He anticipates a growing competitive landscape in the Czech Republic, with Vích, Zajíc, and Friš all poised to challenge the national record. “It’s a challenge for all of us, and not just in the half marathon. The Czech marathon record is even older – 33 years. It’s time to break them.”
Beyond individual performance, factors like weather, course profile, and competition all play a role in achieving optimal times. Vebr highlighted Valencia as a prime location for fast times, citing its flat course, ideal temperatures (10-12 degrees Celsius), and strong competition. “I ran my personal best of 63:24 there and finished around 50th place. Anywhere in the Czech Republic, I would win by five to ten minutes with that time.”
Vebr emphasized the mental aspect of peak performance. “Ideally, you shouldn’t think about anything, get into a state of ‘flow,’ and just become one with the race. Don’t overthink it,” he said with a smile. “But it’s also essential to be well-trained and start the race at the pace you’ve trained for. Less experienced runners can get carried away by the atmosphere and start too fast, which will show around the 10th kilometer when the energy runs out. That’s why the ‘negative split’ is so effective – start a little conservatively and speed up in the final kilometers. That’s where the best performances approach from.”
The remarkable performances of athletes like Jacob Kiplimo continue to redefine the limits of human potential in distance running. As Vebr and other Czech runners prepare for their next challenges, the pursuit of faster times and national records promises an exciting future for the sport.
Patrik Vebr is scheduled to compete in the Prague Half Marathon on March 31, 2025. Stay tuned to Archysport for updates and analysis.
