Sylvain Daniel

I'm a bloody french taking care of marathoners groups. We are doing races together around the world. I have experiences in marathons, ultra-trail, triathlons, bike races, open water swimming and ultrafond.

My book contains my answers to the most recurrent questions that are put to me.

With some tips and to avoid some mistakes, It will help you achieve your goals and your sports dreams.

Bonne lecture et bonne course.
