A record built on the longest races
D'Haene's speciality is the race that lasts longer than a day. Four UTMB wins across nine years, four wins at the Diagonale des Fous (arguably the hardest 165km race in the sport), and a Hardrock 100 title give him a claim to the deepest long-ultra résumé of anyone racing. In September 2024 he won the Tor des Géants, 330km and 24,000m of climbing through the Aosta Valley, at 39.
The mentor role
When Jim Walmsley moved to the Alps to prepare for UTMB, D'Haene was the athlete he trained with and learned the course from. That mentorship is part of why the French long-ultra approach (patient early pacing, aggressive night sections, detailed course knowledge) has spread through the international field.
Where he is right now
He returned to Chamonix in 2025 hunting a record fifth UTMB title, having opened the year with a win at the 100km of Transylvania in May, but withdrew at Lac Combol around 68km with a right-leg problem that had flared up during race week. In 2026 he skipped UTMB altogether: he was third at the 226km Ultra Terrestre at the Ultra Trail des Géants, then in July set a new supported fastest known time on Corsica's 180km GR20 trail, 29:46:20, the first sub-30-hour crossing and 40 minutes faster than the record he had lost to Lambert Santelli in 2021.
How François runs
At 1.92m D'Haene is tall for an ultrarunner, and he races like it: not a light, bouncing climber but a powerful, steady one whose rhythm barely changes between the first hour and the twentieth. His pacing is the core of his method. He is almost always behind the leaders in the first third of a long race, and almost always moving faster than them in the last third.
His power-hiking is among the most efficient in the sport. He is an outspoken advocate of good pole technique, prefers long poles that let him drive with his back rather than his shoulders, and says that when his legs no longer want to push he saves them by pushing on the poles instead. On long climbs he moves at a pace many rivals can only match by running, and because hiking costs less energy he arrives at the top of each climb with more left. On descents he is controlled rather than spectacular, protecting his quads for the second half of the race rather than winning time early.
The other part of his method is time management off the trail. His aid-station stops are short and planned in advance, and he races through the night on courses he has reconnoitred so thoroughly that darkness costs him very little. Over 160km, those habits add up to the margin by which he wins.
Where François is strongest
Point-to-point mountain races that last longer than a day: UTMB, the Diagonale des Fous on Réunion, Hardrock and the 330km Tor des Géants. The longer and more cumulative the climbing, the more his restraint and steady rhythm pay off, and his record over 160km and beyond is the deepest of his generation.
He is less at home in short, fast races where the decisive moves come early and the margins are seconds. His career has deliberately been built around the formats where patience is rewarded rather than punished.
The edge. Pacing discipline. He has repeatedly won races he did not lead until the final quarter.
What you can learn from François
1. Start slower than you think you need to
D'Haene's best races look slow on paper at halfway. For an everyday runner the practical version is to set your effort for the first third of an ultra deliberately below what feels comfortable, using heart rate or breathing rather than the runners around you as the guide. The time you give away early is almost always smaller than the time you would lose by slowing down late.
2. Treat aid stations as part of the race
Minutes lost in aid stations add up to hours over a long ultra. Plan each stop in advance: what you will eat, what you will refill, what you will change. Practise transitions on long training runs, keep your kit organised so you are not searching through bags, and leave as soon as the plan is done. It is the easiest free time available to any runner.
3. Learn the course before you race it
His UTMB wins were built on knowing each descent and each climb in the dark. If you can, run key sections of your goal race in training, or at least study the profile and the technical parts in detail. Knowing what is coming lets you pace climbs properly, eat at the right moments and move confidently at night.
4. Make power-hiking a trained skill
Efficient hiking with poles is how he climbs fast for twenty hours. Add steep hiking intervals to your week, practise the pole rhythm until it is automatic, and on long runs hike the steep sections at a firm, purposeful pace rather than a recovery shuffle. For most ultra runners, better hiking gives back more time than faster running.
