This year the marathon runs in reverse CP order from Mont Tremblant (CP11) to Montebello (CP6) on Saturday and from Montebello (CP6) to Lachute (CP1) on Sunday. The Saturday route is entirely new, starting near Mont Tremblant and travelling south to Montebello. That means that CP11 to CP7 are in completely different locations from CSM 2017.

NOTE: There are trail descriptions as well as the maps on the CSM website at

  • Each section of the trail is referred to by the LOWER numbered CP at either end of the section. So, for example, the trail between CP4 and CP3 is referred to as section 3.
  • Section 6 and section 5 use the same trail in different directions on different days.
    • The road crossings in Sections 6 and 5 BOTH use the Section 5 numbering, as in "RC 5-x".
