Everything you need to know about the UTMB Index 2.0!

You may already know the UTMB Index, the tool developed to gauge your level, guide your race choices, and sometimes compare you to others. Based on a scale from 0 to 1000, this index measures a trail runner’s performance across 4 categories: 20K, 50K, 100K and 100M. Well, turns out its scoring system is evolving for results that are more appropriate, fairer, and more accurate. This new version could be a real boost for all the hesitant runners who pointed out gaps that were sometimes hard to understand. Here are the major changes in the UTMB Index 2.0👇. 

In April 2026, the trail running world got a little makeover 💅. This number gives access to priority registrations, entry into the lotteries for the major UTMB World Series races, and, for elites, direct qualification spots 🚀. The UTMB Index 2.0 has officially come into effect. It’s not just a cosmetic facelift to look nice on your profile. It’s a reprogramming of the algorithm that governs your chances of snagging a bib for the World Series. If you noticed your score moved by a few points (on average a 2% variation), it’s because the tool has become much more "intelligent" 🧠. It no longer just divides your time by the distance; it’s finally trying to understand the suffering and the technicality behind every stride 🏔️.

More factors taken into account 📊

The big revolution is that the index is finally stopping comparing apples and oranges 🥕. Before, a performance on a fast 50 km could sometimes crush a feat on a technical 50 km at high altitude ⛰️. That’s over! The new calculation integrates maximum altitude and slope variations. The goal? Stop comparing performances that have nothing to do with each other in terms of effort 💥. In short, if you climb to 2,500 meters altitude and sweat like a pig, that will be taken into account and rewarded in your time 🐷. Your score now reflects alpine reality, raw effort is rewarded as much as pure speed 💨. It’s excellent news if you love rugged, technical courses where the clock collapses but the commitment is total 🧗‍♂️. Lack of oxygen at altitude is also taken into account 🌬️ .

The other major change is how DNFs (abandonments) are handled ❌. Until now, dropping out of a race could hang over your history like a sword of Damocles. With version 2.0, UTMB lifts that pressure: your DNFs no longer negatively impact your score. So you can decide to stop to avoid an injury without wrecking your stats 😮‍💨. That’s huge news for elites who want to protect their season 😮. In addition, the scoring is based on the best results from your last 3 years, giving more weight to your recent performances 📆. Basically, it’s a model that follows your real form curve, not your past glory from three years ago 😉. We can already picture you saying, "damn, that doesn’t suit me, I’m not as fit as I was in my 20s anymore" 😂.

An interface to anticipate your future 🔮

Because data is great, but understanding it is better, your new runner page becomes a real dashboard. You can now see exactly which races make your average climb (or stagnate) and, above all, anticipate your future progression 📈. The idea is total transparency. You’re no longer facing a mysterious number, but a contextual analysis of your (professional, right 😎) trail running career. Good news for trail moms🤰. Life situations like maternity are now taken into account, with a 5-year index freeze for elite athletes (shout-out to Marion Delespierre, Camille Bruyas...🐣).

In short, the Index 2.0 is fairer, more accurate, and above all much closer to the reality you face every weekend! 🏅 Some runners were right on the edge of the lottery threshold, so this new version can change their access to a race 💪.

So, have you already taken a look at your new 2.0 score? 🤪
