What Is Trail Running?

Trail running is a sport practiced on natural paths, mountains, forests, and off-road terrain. Unlike road running, trail running involves irregular terrain, significant elevation gain and loss, and direct contact with nature. Distances range from 10 km in more accessible races to 100 miles and beyond in ultra trail events.

Trail running races vary widely: from high-altitude skyraces to forest trails on flat terrain, to ultra distances that require days of continuous running. Each race is a unique experience shaped by the landscape it traverses.

How to Use the Race Calendar

Running Around provides a comprehensive tool for finding trail running races worldwide. You can filter races by name, country, region, date, minimum distance (km), and minimum positive elevation gain (D+). The UTMB® Index and ITRA filters let you quickly find races that award points for international qualifications.

The interactive map displays all filtered races with their geographic locations — click a marker to see the race name and access the detail page. Clusters expand as you zoom in, allowing you to explore by geographic area.

UTMB® Index and UTMB Stones

The UTMB® Index is the official qualification system for the Ultra-Trail du Mont-Blanc and events in the UTMB World Series circuit. Qualifying races award Running Stones, which accumulate to earn the right to participate in the most sought-after races in the circuit, including the legendary UTMB® in Chamonix. On Running Around you can filter all races that award UTMB Stones or contribute to the UTMB® Index.

Running Stones range from 1 to 3 per race based on course difficulty and length. The UTMB® Index also accounts for performance relative to the field, rewarding results in terms of ranking and finish time.

ITRA Points and Performance Index

The ITRA (International Trail Running Association) is the international organization that certifies trail running races worldwide. ITRA-certified races award points based on course difficulty (distance and elevation) and athlete performance. ITRA points are used as an admission criterion for numerous international races, including the CCC and TDS in the UTMB circuit.

The ITRA Performance Index is a personal index that measures an athlete's level in trail running, calculated based on results achieved in ITRA-certified races over the last three years. On Running Around you can find all races that award ITRA points, easily selectable through the dedicated filter.

Trail Races in Italy and Worldwide

Running Around covers hundreds of trail running races in Italy — from the Alps to the Apennines, from Liguria to Sicily — and around the world, with events in Europe, Asia, North America, and Oceania. In Italy, the most represented regions include Piedmont, Valle d'Aosta, Trentino-Alto Adige, Veneto, Lombardy, and Liguria, where the mountainous terrain offers technically challenging and scenic courses.

Internationally, the database includes races in France, Switzerland, Spain, Austria, Slovenia, and many other countries. Whether you're looking for a local race for your trail running debut or a high-level international ultra trail, Running Around is the ideal starting point for planning your next running adventure.

Frequently Asked Questions about Trail Running

How do I find trail running races in a specific region?

Use the Region filter in the Running Around calendar to filter races by geographic area. Combine it with the distance (km), elevation (D+) and date filters to find exactly what you're looking for among thousands of races.

What is a UTMB® Running Stone and how many do I need?

Running Stones are credits in the UTMB® circuit, awarded from 1 to 3 per race based on difficulty. To enter the UTMB® in Chamonix you typically need 3 stones within 3 years. Filter qualifying races with the UTMB® Index/Stones toggle.

Are ITRA points different from UTMB Running Stones?

Yes. ITRA points measure athlete performance relative to the race field and are required for races like CCC and TDS. UTMB Running Stones reward participation in circuit races regardless of finishing position.

What distance qualifies as an ultra trail race?

Ultra trail races conventionally start at 50 km, though many use the term from 42 km. Distances range from 50 km to 100 miles (160 km) and beyond. Use the distance slider to filter by race length.

How do I choose my first trail running race?

For a first trail race, aim for 10 to 25 km with moderate elevation gain (under 1000m D+). Look for well-organized events with clear course marking. Set the km filter on Running Around to your target distance to find beginner-friendly options.

Do trail races require a qualification to enter?

UTMB World Series races require Running Stones as an entry requirement. Many trail races are open to everyone with no qualification needed. Always check the individual race rules — follow the registration link from the Running Around race detail page.
