How could we imagine one day of March 1979, the idea of organizing a race opened to everyone between Marseilles and Cassis could take such an International dimension? A very young athletic section, a group of close friends and the unfailing support of every sections of an “omnisport” club, the SCO Ste Marguerite, gave birth to the first French Classic race.
With 700 runners for its first Edtion, this race where the popular and convivial spirit rules welcome every year more and more enthusiasts and count from now 12 000 participants. Such a keen interest for the race contributed to other events on the occasion of the last week end of October.
Since 1990, the ramble “L’Autre Marseille-Cassis” organized the day before the Classic in the massif of the “Calanques” gathered 1800 walkers and is directed to the awareness of everyone for the environment and assets respect.
The sporty ramble created in 2006 gives the possibility to a lot of walkers to follow the runners to reach the Gineste under another form of sport. This success, built over 44 years of existence, belongs to the 600 volunteers of the SCO Ste Marguerite who never hesitate to mobilize themselves to welcome a thousand of people in the best conditions.

What runners say about us?
Said López
running.COACH has helped me plan my entire season for the year. I love the flexibility with which the training plan is adjusted when an annual goal changes. I am very happy with the way it plans my week, the accuracy of the pace and heart rates, and the ease of use of the app. I find the dashboard very accurate and the stats help me keep a clear track week after week. This year my goal is to reach 800 ITRA points at three mountain ultras in Colombia, and I hope to do it with the help of running.COACH.
Karin Stoop
With the training program from running.COACH, I was able to achieve the goal of a "marathon" within a year with a varied training plan that was adapted to my performance. It is impressive how tailor-made this online training program is. My dream of finishing a marathon has come true. The different training units and the noticeable progress are very motivating.
Monika Cremosnik
Thanks to the support of my running.COACH Gold Coach, Stefanie Meyer, this year became my year of success! Intensive and always personalised training plans and always the right words and encouragement have helped me to realise my dreams. I am now a finisher in the ultramarathon in South Africa, the Comrades Marathon.
Silvia Perez
When I started training with running.COACH I found it hard to lower the intensity of each workout. But I continued because I believe that "less is more". With running.COACH I not only continue to improve my times and meet my goals but I feel strong and in very good shape. This is what allows me to finish a competition happy and keep on doing what i like the most: RUNNING!!
Angela Heller
"When I started running again after a long break, it was clear to me that I wanted to train in a structured way. With the reference 'Viktor Röthlin' my confidence grew and I bought my first subscription, a silver subscription. I was enthusiastic from the beginning and my motivation increased from training session to training session. I followed the instructions very precisely and the result for my big goal, the SwissAlpine K43, was correspondingly perfect!"
Christoph Friedli
Thanks to continued training with running.COACH, I was able to clearly improve on distances ranging from 10km to mountain running and marathon in the past couple of years, without risking an injury. Those successes encourage me to aim at new targets time and time again.
