CLUT – Cento Laghi Ultimate Trail

A trail among the Cento Laghi of the Parma Apennines

The CLUT – Cento Laghi Ultimate Trail is the trail running event that has elected Corniglio, a small mountain municipality in the Province of Parma, as the capital of mountain running in the Tuscan-Emilian Apennines. The name recalls the famous "Cento Laghi" (Hundred Lakes) area, the system of glacial bodies of water — including the Lago Santo Parmense, the largest and deepest natural lake in the northern Apennines — nestled among the ridges of the Tuscan-Emilian Apennine National Park and the Ducal Parks.

The race is organized by Parmarathon ASD in collaboration with the Municipality of Corniglio and carries on the legacy of previous races in the area. The headquarters are located in Piazza Castello, in the center of Corniglio, which houses the secretariat, bib collection, changing rooms, and the final pasta party.

Four races for every level

The beauty of CLUT is the possibility to choose the distance that best suits your preparation, from a sporting walk to an ultra challenge:

• CLUT 70 — 70 km and approximately 4,750 m of positive elevation gain, the queen event starting from Piazza Corniglio. It is included in the national calendar as a stage of the IUTA UltraTrail Grand Prix.
• CLUT 32 — 32 km and approximately 2,000 m of elevation gain, starting from the Lagdei location, reachable by dedicated transfer from Corniglio.
• CLUT 18 — 18 km and approximately 1,100 m of elevation gain, an afternoon start from Piazza Corniglio.
• CLUT 10 — 10 km and approximately 460 m of elevation gain, the most accessible distance, perfect for those new to trail running.

All races are valid for the Parma Trail Running Circuit. The competitions are surrounded by a program of collateral events with food stands, DJ sets, guided treks, and mini trails for children.

A unique natural stage

Running the CLUT means crossing some of the most evocative landscapes of the northern Apennines: ancient beech forests, high-altitude meadows, the ridge marking the border between Emilia and Tuscany, and, of course, the glacial lakes that give the event its name. A day of sport that is also an opportunity to discover the identity of a mountain territory often little known, made up of villages, traditions, and Apennine gastronomy.

For nature running enthusiasts, the Cento Laghi Ultimate Trail is now a fixed event in the late May calendar, capable of attracting athletes from all over Italy to Corniglio.
