Kilian Jornet - Trail Runner Profile
Kilian Jornet is a Catalan mountain runner and ski mountaineer widely regarded as the greatest trail runner of all time. He has won UTMB four times (2008, 2009, 2011 and 2022), the Hardrock 100 five times, Zegama-Aizkorri eleven times and Sierre-Zinal ten times, and holds speed records on peaks from

Why he is considered the GOAT
No other trail runner has won at this range. Jornet's four UTMB titles span fourteen years (2008, 2009, 2011 and 2022), and the 19:49:30 he ran for the last of them stood as the course record until Jim Walmsley's 19:37:43 in 2023. In the same career he collected five Hardrock 100 wins, eleven victories at Zegama-Aizkorri and ten at Sierre-Zinal, races of 42km and 31km where the winning margins are minutes, not hours. Very few athletes in any endurance sport have dominated a three-hour race and a twenty-hour race in the same summer.
Beyond racing
His Summits of My Life project took the same approach to mountaineering: round-trip speed records on Mont Blanc, the Matterhorn, Denali, Elbrus, Aconcagua and finally Everest, which he summited twice in a week in May 2017 without supplemental oxygen or fixed ropes. He also broke the Bob Graham Round record in the English Lake District. Off the mountain he co-founded the equipment brand NNormal and, with Francesco Puppi and Pascal Egli, the Pro Trail Runners Association.
Where he is right now
Jornet spent 2025 racing the big American ultras rather than the European circuit: second at the Chianti Ultra Trail by UTMB behind Walmsley, then a well-paced third at the Western States 100. His 2026 has been interrupted. He did not finish at Western States and then withdrew from UTMB, announcing surgery on a knee problem that had troubled him for months.
How Kilian runs
Jornet is not the fastest runner on flat ground in most of the fields he beats, and he has never needed to be. His racing is built on economy in the mountains: a short, quick stride on climbs that switches to power-hiking the moment running stops paying for itself, and a descending style that looks closer to skiing than running, with the eyes several steps ahead, the hips loose and the feet placed almost by reflex on loose rock and mud.
Underneath that technique is an aerobic base built very differently from most runners'. Through the winter he trains mainly on skis rather than on foot: ski mountaineering and cross-country skiing blocks of up to 30 to 35 hours a week, piling up enormous amounts of climbing with almost none of the impact cost of running. When he switches back to the trails in spring, the engine is already there and the running volume needed to sharpen it is relatively small.
In races he is patient and opportunistic rather than a front-runner. He often sits in the group through the early hours, studies how rivals are moving on the climbs, and makes his decisive move on the terrain that suits him: a technical descent, a steep ridge or the final big climb. Over a long career that tactical flexibility has let him win 31km races decided by seconds and 100-milers decided by hours, often in the same summer.
Where Kilian is strongest
Steep, technical, high-alpine terrain at almost any distance between 20km and 100 miles. Zegama-Aizkorri's mud and ridges, Sierre-Zinal's long Alpine traverse and Hardrock's high passes in the San Juan Mountains are all places where his descending and line-reading turn into minutes on the clock.
He is relatively weaker where a course rewards sustained flat speed. On fast, runnable 100-milers such as Western States, specialists with road and track backgrounds can match or beat him, which is why his 2025 third place there was treated as an achievement rather than a disappointment.
The edge. Range. He has stayed competitive at 31km and 160km in the same season for well over a decade, which no other athlete in the sport has sustained.
What you can learn from Kilian
1. Build your aerobic base with a second sport
Jornet's winters on skis are a large part of why he could race at the top level for two decades. For most runners the equivalent is a regular block of cycling, ski touring, uphill hiking or rowing in the off-season: long, steady aerobic work that keeps the engine growing without adding pounding to the legs. It is one of the most reliable ways to raise your volume without raising your injury risk.
2. Practise descending as a skill, not as recovery
Most amateur trail runners lose more time on descents than on climbs, and most never train them deliberately. Borrow Jornet's priorities: look three or four steps ahead rather than at your feet, keep your cadence high and your steps short on loose ground, and spend a session a week running controlled repeats down technical terrain. Confidence on the way down is trainable, and it saves energy as well as time.
3. Know when to stop running uphill
On steep climbs Jornet switches to a fast hike much earlier than most recreational runners would expect. Hiking efficiently, hands on thighs or with poles, is often as fast as a laboured jog and costs far less. Practise power-hiking on your long runs so it becomes a gear you can use with intent on race day rather than a sign you have given up.
4. Keep short races in your long-distance year
His 2022 season is a good example: he deliberately alternated short and long races, setting a course record at Zegama, then racing Hardrock, then Sierre-Zinal, before winning UTMB in 19:49:30. Shorter races keep your top-end speed and leg turnover alive, sharpen your descending under pressure and let you practise racing tactics without the recovery cost of an ultra. A 20 to 30km mountain race eight to ten weeks before a goal 100km is a sensible place to start.

Frequently asked questions
How many times has Kilian Jornet won UTMB?
Four times: 2008, 2009, 2011 and 2022. His 2022 winning time of 19:49:30 was a course record until Jim Walmsley ran 19:37:43 in 2023.
Is Kilian Jornet still racing in 2026?
Only partly. He did not finish the 2026 Western States 100 and then withdrew from the 2026 UTMB, announcing that he would have surgery on a long-standing knee injury.
What is Kilian Jornet's ITRA index?
941 on his ITRA profile as of August 2026, among the highest ever recorded. The index runs to a maximum of 1,000 and uses a runner's five best results from the previous 36 months.
