9TH EDITION

We are thrilled to invite you to the 2025 edition of the TZT Merzouga, from Friday, October 10, to Saturday, October 18, 2025, set against the breathtaking landscapes of Merzouga, Morocco! This exceptional event will challenge you across a 200-kilometer course, divided into five intense stages that traverse the stunning dunes and rugged terrain of the Sahara.

TZTM 2025 is more than just a race, it’s an adventure that combines endurance, camaraderie, and the discovery of Morocco’s rich desert culture. Each stage brings a new challenge, and every evening offers a bivouac experience under the stars, fostering connections and unforgettable memories with fellow runners.

With the support of our dedicated team at each checkpoint and bivouac, you’ll have everything you need to focus on the journey, embrace the challenge, and make lasting memories in one of the world’s most awe-inspiring landscapes. Join us for TZTM 2025 and prepare for an experience of a lifetime!

Each year, the non-profit organization Run To Start organizes the TZTM in Morocco in order to raise funds for the different associative projects.

In 2021 and 2022 Run To Start organized also the Kasterlee Trail in Belgium in order to raise additional funds for the association. More infos about the Kasterlee Trail

Thanks to these events but also to other fundraising organized throughout the year the association Run To Start was able to expand and set up various projects for the Boutyouss region and with the moroccan association APCIZ in the region of Zagora, the region where the first editions of the TZT was held.
