2017 – The Regulations


Dear trailers, with this event comes an enormous privilege.

You are fortunate to be participating in this event that will take you through fragile, protected areas, and in particular the magnificent Parco del Marguareis.

In such places respecting fauna and flora is essential: you must stay on the paths and tracks, following our “balisage” (path markers) without straying off them. Only let your eyes wander, not your feet, to ensure that what Mother Nature wants to preserve remains preserved. You will find a drop zone for your rubbish. On some grassy slopes you may find herds of animals grazing; keep vigilant, and don’t disturb them. Keep an eye out for the sheepdogs that the shepherds use to guard the flocks.

Be vigilant: you will be disqualified and fined if you don’t follow these rules.

Some details of the organization have yet to be defined, so please understand, these rules are to be considered PROVISIONAL until stated otherwise

Stay tuned !!

Any and all updates will always be brought to your attention in the News section

Art.01 – Organization


The Association Cro Trail (Association under the Law of Association Ref. 1901, France),in collaboration with “La Via del Sale a.s.d.”,organizes in semi self-sufficiency: the ultra-trail LIMONE-BREIL-MENTON, on date 8/9 July 2016 known as TRAIL DU CRO , the TRAIL MARGUAREIS (LIMONE- BREIL) , TRAIL OF FRENCH RIVIERA.

Art.02 – The Events

The Trail Cro  (LIMONE-BREIL-MENTONE), is an Alpine ultra-trail, of about 115 km and a total positive altitude change of + 7000m and a negative one of 7900m, starting from Limone, passing through Breil sur Roya and finishing in Menton on the Côte d’Azur.

The course connects the twin towns of Limone Piemonte (Italy) and Menton on the Côte d’Azur (France) crossing the Southern Alps, , mostly on alpine trails, and finishing next to the Mediterranean on the beach near the port, which runs mainly on mountain paths.

The course consists of a number of passages at altitude, up to 2400m, and the conditions can be difficult (extreme cold, wind, fog, rain and even snow!!). Certain weather conditions can become “extreme”. The route presents different difficulties and techniques. An adequate training, a knowledge of the mountains and mental strength and self sufficiency are indispensible to succeed in this endeavour.

The start will be at 17.00 on the 7th July, from Limone Piemonte.

At the same time, on the same course two other trail races will be run. The first from Limone to Breil (80km, 5400m of positive altitude change, 5900m of negative altitude change) crossing the Parco del Marguareis, and called the “Trail du Marguareis” and there will be another trail called “Trail della Riviera Francese” which goes from Breil to Menton (35 km, 1700mD+, 2000mD-, start at 14,30, July 8th , Breil sur Roya)

These ultra-trails open out together at the same time and impose a certain degree of organization and self-sufficiency on participating competitors. They must always carry with them the obligatory equipment as per the list at Art. 16. In particular in the first section,, the Alpine one, a very important aspect is clothing temperatures can drop below 0°C and snowfalls may occur.

The Trail du CRO starts at Limone Piemonte, up on the ridge that marks the Italian-French border, through the Park Marguareis, follows the ridge south for tens of kilometers, crosses the Alpes Maritimes and drops to Breil sur Roya. Beyond that the route passes through Sospel, and generally following the GR trail ends at the beach at Menton, near Monaco. This is a very demanding course.

The maximum time allowed for completion of each of the events is: 30 hours for the Cro; 21 hours for the Trail du Marguareis, and 9 hours for the Trail of the French Riviera. The time barriers include all breaks. Intermediate time limits (hour barriers) have been set for each specific checkpoint, and can be found in the road-book and on the event’s web site. These hour barriers are calculated to enable participants to reach the Finish line within the maximum allowed time, including eventual breaks.

To be authorized to continue the event, competitors must set off again from the control post before the fixed hour barrier, otherwise the competitors will be disqualified and their bib will be withdrawn.

ATTENTION! The “BALAI” (Sweeper) when he passes will remove all marks from the course (balises, signposts, etc). It may be risky and dangerous to continue on the course without a bib / despite his or her disqualification: the Organizers decline any responsibility for any incident and/or accident that may occur to the disqualified competitor if he insists on going on.

Art.03 – Acceptance of the Regulations and the Chart

he Cro-Trail, the Trail of Marguareis and the French Riviera Trail individual all take place in accordance with the present REGULATIONS, to be consulted and downloaded from the website “www.crotrail.com”.

The competitor undertakes to comply with these Regulations and the Chart upon entry to this event, and thereby releases any claim against the Organization for any incident and/or accident that may arise following his non-compliance with the aforementioned Regulations and Chart.

Any runner seen throwing his rubbish on the course will be penalized or disqualified.

Dustbins have been placed at each refreshment post and must be used.

It is imperative to follow the paths as marked (balises), without shortcutting. In fact, to shortcut a path causes an irreversible erosion of the site and thus degrades it irremediably.

Art.07 – Checks at the Start of the Race

Each competitor will receive a bib with chip incorporated inside. At the start he will have to register by registering this chip, presenting the bib pinned in front, at the waist. Without registering the competitor will not be classified.
Competitors must have in their backpack all material required, otherwise he/she will not be consented  to leave.  A check of the backpacks is expected at the time of delivery of the bibs and departing; checks will be possible on the path.

The organization reserves the right to conduct inspections of backpacks during the competition.

Art.08 – Checkpoints

Checkpoints are established along the course and constitute points of compulsory clocking-in of the Race Chip for the competitors.

The clocking-in at each Checkpoint will allow the timekeeper to establish the classification of each competitor. Clocking-in is essential for the safety as by cross controlling the passages at two adjacent checkpoints it will be possible to verify that no competitor is missing. In the case of not clocking-in, the competitor will be held responsible for all of the consequences, for which the competitor will be asked to bear the costs.

The registering at the finishing line will enable the timekeepers to establish the results.

Each competitor delayed by helping and/or assisting any fellow one, or other participating staff, may request a time credit for the delay experienced at the closest Checkpoint.

A back-pack/bag and equipment check can be carried out at any given time during the competition
