The figures from the International Trail Running Association (ITRA) leave no doubt: roughly 2 million registered trail runners worldwide, 611.000 annual entries just in the ultra segment. That represents growth of 1.676 percent since 1996. <\/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-top:3px solid #00D4D4;\">\n<div style=\"font-size:28px;font-weight:700;color:#1a2a2e;\">1.676 %<\/div>\n<div style=\"font-size:12px;color:#666;margin-top:4px;\">Growth since 1996<\/div>\n<\/div>\n<div style=\"flex:1;text-align:center;background:#d6eaf0;border-radius:8px;padding:20px 12px;border-top:3px solid #00D4D4;\">\n<div style=\"font-size:28px;font-weight:700;color:#1a2a2e;\">38 %<\/div>\n<div style=\"font-size:12px;color:#666;margin-top:4px;\">Female share 2024<\/div>\n<\/div>\n<div style=\"flex:1;text-align:center;background:#d6eaf0;border-radius:8px;padding:20px 12px;border-top:3px solid #00D4D4;\">\n<div style=\"font-size:28px;font-weight:700;color:#1a2a2e;\">64<\/div>\n<div style=\"font-size:12px;color:#666;margin-top:4px;\">UTMB Events 2026<\/div>\n<\/div>\n<\/div>\n<p> And in the last ten years alone: plus 345 percent. This isn\u2019t just statistical fluff. It\u2019s thousands of people lining up at a start line somewhere in the world each week, where there is no road any more\u2014only trails, roots, rocks and a finish line hidden behind a mountain. What the numbers don\u2019t show is how many people simply run. No race registration, no GPS watch, no Strava upload. They head into the woods in the morning and return with muddy shoes in the evening. They\u2019re not in any statistic, but they\u2019re the reason Hoka and Salomon can\u2019t produce trail shoes fast enough. Over 80 percent of trail\u2011running consumption now happens digitally, according to Nielsen Sports\u2014livestreams, social media, podcasts, real\u2011time results platforms. You don\u2019t have to be in Chamonix to experience the UTMB. You can sit in your living room and watch Courtney\u202fDauwalter race. Then head out yourself the next morning. That\u2019s exactly what\u2019s happening millions of times right now. <\/p>\n<p>&nbsp;<\/p>\n<h2 style=\"line-height: 1.5;\">Istria 100: Trail Running this week<\/h2>\n<p> &nbsp; The Istria 100 by UTMB takes place from 10 to 12 April 2026 on the Croatian peninsula of Istria. 3.000 runners from around the world. Five distances: 168 Kilometer (the full 100 miles), 110 Kilometer, 69 Kilometer, 42 Kilometer and 21 Kilometer. The race has existed since 2013 and has become one of the most important UTMB World Series events in Europe. What makes the Istria 100 special: the course combines coastal paths along the Adriatic with dense forests and medieval towns inland. You run through Gro\u017enjan, an artist village on a hill that looks like a movie set at night. You cross the Mirna Gorge. And if you run the 100\u2011mile distance, you do it all at night. With a headlamp, in a field of crazy people who know exactly why they are there. The top 3 of the 50\u2011Kilometer, 100\u2011Kilometer and 100\u2011Mile distances qualify directly for the three UTMB World Series finals. Anyone who finishes the 100 Kilometer under 18 hours is eligible for the lottery for the Western States Endurance Run 2027. Western States is the oldest 100\u2011mile race in the world and for many trail runners what the <a href=\"https:\/\/www.inspiredbysports.com\/en\/marathon-for-beginners-your-16-week-plan-to-success\/\" style=\"color:#008B8B;text-decoration:none;border-bottom:1px solid rgba(0,139,139,0.3);\">Marathon<\/a> is for road runners. Almost 30 percent of all starters in the last edition were women. 92 percent of them finished. That is no coincidence. According to ITRA, the female share in trail running has risen from 15 percent in 2005 to 38 percent in 2024. Trail running is one of the few endurance sports where the gender gap is visibly shrinking. That also has to do with the course: on technical trails, technique matters more than pure strength. The longer the distance, the smaller the performance gap between men and women. In races over 200 miles, there are women who win the overall classification. <\/p>\n<p>&nbsp;<\/p>\n<h2 style=\"line-height: 1.5;\">Why Trail Running is different from Running<\/h2>\n<p> &nbsp; Anyone who has ever veered off the road onto a forest path knows: it\u2019s a different sport. On the road, pace matters. On the trail, not falling matters. And that you find the way. And that you have enough water with you. And that you know when to turn back. Trail running is running plus adventure plus risk management. Trail running challenges your whole body. Every step is different. Roots, rocks, descents, climbs. Your ankle joints work constantly, your core stabilises every stride, your eyes scan the ground three metres ahead. Your brain runs just as hard as your legs. If you can zone out on the road, you have to stay highly focused on the trail. And that\u2019s exactly what many people love about it. <\/p>\n<div style=\"background:#F7F9E4;border:1px solid #eef0d8;border-radius:8px;padding:16px 20px;margin:24px 0;\"><strong style=\"color:#1a2a2e;\">Tip:<\/strong> Start with short trails (<\/p>\n<h2 style=\"line-height: 1.5;\">Your Start: What You Really Need<\/h2>\n<p> &nbsp; Not much. That&#8217;s the point. Trail running is one of the most accessible endurance sports out there. Here\u2019s what you need and what you can skip. **Trail shoes (100-160 Euro):** The only mandatory purchase. Road running shoes have zero grip on wet forest floor. Choose a shoe with a Vibram sole or a comparable tread. Salomon Speedcross, Hoka Speedgoat or Brooks Cascadia are classics. Try them on in a store, not online. **Hydration vest (60-120 Euro):** Once you\u2019re doing a 15\u2011kilometre trail you\u2019ll want one. Anything less can be covered by a handheld bottle. Salomon ADV Skin and Camelbak Zephyr are entry\u2011level standards. Make sure it doesn\u2019t bounce when you run downhill. **Headlamp (30-60 Euro):** Not just for night runs. In the forest it gets dark around 4\u202fp.m. in autumn. Petzl Actik or Black Diamond Spot are solid. 300 lumens are enough. **What you don\u2019t need:** GPS watch (your phone is fine), compression socks (studies show they don\u2019t boost performance), poles (only useful after 30+ kilometres with lots of elevation), a training plan (just run; the trail sets the plan for you). **Rain jacket (80-150 Euro):** For races over 30 kilometres it\u2019s usually required gear. Even without a race: forest weather changes quickly. A packable jacket (under 200\u202fg) fits in any hydration vest. Gore\u2011Tex Shakedry or similar membranes are the standard. The most important piece of equipment isn\u2019t a piece of gear at all: a forest, a park or a hill near you. If you have a <a href=\"https:\/\/www.inspiredbysports.com\/en\/outdoor-yoga-first-park-session\/\" style=\"color:#008B8B;text-decoration:none;border-bottom:1px solid rgba(0,139,139,0.3);\">park right outside your door<\/a>, you have everything you need. Most trail runners don\u2019t have the Alps nearby. They have a city forest, a river path, a hill. That\u2019s enough. The trail is wherever you find it. <\/p>\n<blockquote style=\"border-left:4px solid #95C2D5;margin:24px 0;padding:16px 20px;background:#f0f7fa;border-radius:0 8px 8px 0;font-size:1.05em;line-height:1.6;color:#333;\"><p> &#8220;Trail running has no club or federation you need to worry about.
