The trademarks "MARATHON DES SABLES" and "MDS" and the trademarks of its partners on the Website are registered trademarks. Any reproduction of those trademarks and/or logos, in whole or in part, without the written consent of ATLANTIDE ORGANISATION INTERNATIONALE or CIMBALY INTERNATIONAL (RCS TROYES 383 152 410) is prohibited. Any unauthorised reproduction of such marks, logos and distinctive signs shall constitute an infringement and shall be liable to criminal penalties. The offender is liable to civil and criminal penalties and in particular to the penalties provided for in Articles L.335-2 and L.343-1 of the French Intellectual Property Code.

Similarly, ATLANTIDE ORGANISATION INTERNATIONALE is the producer of the Website's databases. Consequently, any extraction and/or reuse of the database(s) within the meaning of Articles L 342-1 and L 342-2 of the French Intellectual Property Code is prohibited.

In this regard, the Participant expressly authorises the Organiser to grant the same rights on his Image to the partners of the event. To this end, each Participant expressly and irrevocably authorises the Organiser, its successors in title and assigns (in particular its commercial partners), in order to meet the requirements of advertising, promotional and/or commercial and/or information campaigns, to i) to make any modification, addition or deletion that they deem useful for the exploitation of his/her Image under the conditions defined above, ii) to associate and/or combine with his/her Image, all signatures, catchphrases, slogans, captions, trademarks, distinctive signs, legal notices, visuals and, in general, any element of any kind chosen by the Organiser, intended in particular to illustrate the communication media in which they are integrated.

Article 14. Application of the General Terms and Conditions of Sale

ATLANTIDE ORGANISATION INTERNATIONALE reserves the right to amend its General Terms and Conditions of Sale at any time.

In the event of amendment, the General Terms and Conditions of Sale applicable shall be those in force on the date of purchase of the Entry Package, a copy of which, dated on this date, may be given to the Participant on request.

The invalidity of a contractual clause shall not result in the invalidity of the General Terms and Conditions of Sale unless it is an impulsive and decisive clause that has led one of the parties to conclude the Contract of Sale.

If ATLANTIDE ORGANISATION INTERNATIONALE fails to avail itself of any of these General Terms and Conditions of Sale, it shall not be construed as a waiver to avail itself of these terms and conditions in the future.

The temporary or permanent failure to enforce one or more clauses of the General Terms and Conditions of Sale by ATLANTIDE ORGANISATION INTERNATIONALE shall also not constitute its waiver of the other clauses of the General Terms and Conditions of Sale, which shall continue to be fully effective.
