Ahead of them lie 171 kilometres, 10,000 metres of elevation gain, and at least one night in the mountains. Tom Evans conquered this race in 2025 in 19 hours and 18 minutes-after dropping out here in the two previous years. He wasn\u2019t leading for long. He simply navigated the descents and the darkness better than the rest.

Everyone who knows the race warns against exactly that. Before reaching Courmayeur, the major checkpoint in Italy at around 79 kilometres, there are several long climbs and the first technical descents. Anyone who follows the pace of the early leaders here has already lost the second half of the race before it even begins.<\/p>\n<p>Tom Evans took the opposite approach in 2025. He let the early front-runners pull away, tackled the climbs efficiently by alternating between running and brisk walking, and stuck to his own plan. This isn\u2019t caution born of hesitation-it\u2019s a calculated bet on physiology: a body that doesn\u2019t overreach in the opening hours still has reserves after 100 kilometres. Les Contamines at 31 kilometres and Courmayeur are the points where the field visibly begins to stretch out.<\/p>\n<div style=\"display:flex;gap:16px;margin:32px 0;\">\n<div style=\"flex:1;text-align:center;background:#d6eaf0;border-radius:8px;padding:20px 12px;border:1px solid rgba(0,212,212,0.35);box-shadow:0 0 14px rgba(0,212,212,0.12);\">\n<div style=\"font-size:28px;font-weight:700;color:#1a2a2e;\">171 km<\/div>\n<div style=\"font-size:12px;color:#666;margin-top:4px;\">Distance with around 10,000 metres of elevation through three countries<\/div>\n<\/div>\n<div style=\"flex:1;text-align:center;background:#d6eaf0;border-radius:8px;padding:20px 12px;border:1px solid rgba(0,212,212,0.35);box-shadow:0 0 14px rgba(0,212,212,0.12);\">\n<div style=\"font-size:28px;font-weight:700;color:#1a2a2e;\">19:18:58<\/div>\n<div style=\"font-size:12px;color:#666;margin-top:4px;\">Winning time for Tom Evans in 2025 in wet, stormy conditions<\/div>\n<\/div>\n<div style=\"flex:1;text-align:center;background:#d6eaf0;border-radius:8px;padding:20px 12px;border:1px solid rgba(0,212,212,0.35);box-shadow:0 0 14px rgba(0,212,212,0.12);\">\n<div style=\"font-size:28px;font-weight:700;color:#1a2a2e;\">67 %<\/div>\n<div style=\"font-size:12px;color:#666;margin-top:4px;\">Finish rate 2025: 1,665 of 2,492 starters completed the race<\/div>\n<\/div>\n<\/div>\n<h2 style=\"line-height: 1.5;\">Why the descents from Grand Col Ferret break the race<\/h2>\n<p>The highest point of the course is at Grand Col Ferret, 2,537 metres above sea level, roughly 108 kilometres from the start. From there, the route winds its way downhill-often technically-over long stretches. And it\u2019s precisely those downhill sections that pack the real punch. Every descent places an eccentric load on the quadriceps, meaning the muscles lengthen under tension. This type of strain tears fine structures in the muscle tissue. The marker enzyme creatine kinase, or CK, can rise 20- to 100-fold above resting levels during an ultra.<\/p>\n<p>The insidious part is the delayed onset. The damage barely hurts in the moment it occurs. It accumulates and strikes in the second half of the race, when every downhill step sets the thighs ablaze and the next climb feels like a wall. That\u2019s why many top-tier runners drop out after Courmayeur or on the Swiss section. It\u2019s rarely just a matter of pace. More often, it\u2019s wrecked legs, stomach issues, or a missed time cut. The <a href=\"https:\/\/www.inspiredbysports.com\/en\/hardest-heights-teach-recovery\/\">muscle damage ultrarunners only feel during recovery<\/a> explains why the race unravels on the descents rather than on the flats.<\/p>\n<div style=\"margin:32px 0;\">\n<div style=\"display:flex;gap:16px;align-items:flex-start;margin-bottom:20px;\">\n<div style=\"flex-shrink:0;width:76px;text-align:center;background:linear-gradient(135deg,rgba(0,255,255,0.1),rgba(0,212,212,0.15));border-radius:8px;padding:8px 4px;border:1px solid rgba(0,255,255,0.3);\">\n<div style=\"font-weight:700;color:#0a8a8a;font-size:0.82em;line-height:1.2;\">17:45<\/div>\n<div style=\"color:#888;font-size:0.72em;margin-top:2px;\">0 km<\/div>\n<\/div>\n<div>\n<p style=\"margin:0 0 4px;font-weight:700;color:#1a2a2e;\">Chamonix, mass start<\/p>\n<p style=\"margin:0;color:#555;line-height:1.6;\">As dusk falls, the field sets off toward Les Houches.

Sub-24-hour runners consistently consume 90 to 100 grams of carbohydrates per hour, a mix of gels, cola, and solid food at roughly 15 aid stations. It sounds-and is-like a lot. The stomach must process this volume over twenty hours while the body operates under sustained stress. Many lose the race to a rebellious gut because they never tested this intake under load.<\/p>\n<p>Then there\u2019s sleep-or rather, the lack of it. The leaders run straight through the night and cross the line the following afternoon in daylight. The chasing pack faces two nights on course. The second is the tougher one. Sleep deprivation doesn\u2019t just sour moods; it clouds perception and judgment. After Champex-Lac at 125 km and Trient at 139 km, the focus shifts from pace to clean management of the final hours.<\/p>\n<p>In the end, the numbers speak plainly. In 2025, of 2,492 starters, 1,665 reached the finish line-a finish rate of about 67 percent. The average finisher spent 38 to 40 hours on course. Tom Evans covered the same distance in 19 hours 18 minutes. The gap isn\u2019t down to talent alone, but to the ability not to lose a race downhill and in the dark.<\/p>\n<div style=\"margin-top:20px;padding:28px 25px 8px;background:linear-gradient(135deg, rgba(0,212,212,0.08) 0%, rgba(149,200,219,0.12) 100%);border-radius:12px;border:1px solid rgba(0,255,255,0.35);box-shadow:0 0 18px rgba(0,255,255,0.12);\">\n<h2 style=\"line-height:1.5;margin:0 0 8px 0;font-size:1.4em;color:#1a2a2e;display:flex;align-items:center;gap:10px;\"><img decoding=\"async\" src=\"https:\/\/www.inspiredbysports.com\/wp-content\/uploads\/2018\/05\/pfeil.png\" alt=\"\" style=\"width:28px;height:28px;opacity:0.8;\"> Cool-down<\/h2>\n<p style=\"margin:0 0 16px;font-size:0.88em;color:#666;\">Click on a question to reveal the answer.<\/p>\n<details style=\"margin:0 !important;padding:0 !important;border-bottom:1px solid rgba(0,212,212,0.15);background:transparent !important;\">\n<summary style=\"display:flex !important;align-items:center !important;justify-content:flex-start !important;gap:12px !important;padding:16px 4px !important;cursor:pointer;list-style:none !important;font-size:1.05em;font-weight:600;color:#1a2a2e;line-height:1.4;text-align:left !important;margin:0 !important;\"><img decoding=\"async\" src=\"https:\/\/www.inspiredbysports.com\/wp-content\/uploads\/2018\/05\/pfeil.png\" alt=\"\" style=\"width:18px;height:18px;min-width:18px;opacity:0.6;transform:rotate(-90deg);transition:transform 0.3s ease;\" class=\"ibs-faq-arrow\"> What exactly is the UTMB?<\/summary>\n<div style=\"padding:0 0 18px 30px;color:#333;line-height:1.7;font-size:0.96em;text-align:left;\">The Ultra-Trail du Mont-Blanc is a roughly 171-kilometre mountain race with about 10,000 metres of elevation gain around the Mont-Blanc massif, passing through France, Italy and Switzerland.
