- The town makes up the first 5k and final 6k of each loop. It is hilly and offers limited shade, but great crowd support. It runs from the Tremblant village to the Old village. On the return leg you run halfway up the Tremblant village hill, before descending to begin your 2nd lap, or head to the finish.
- Le P'tit Train du Nord makes up the middle 10km of each loop, and is a paved rail trail through wooded forest that is relatively flat and provides shade.
- Race morning can be cold, be sure to bring warm close to the swim start that you can leave in a morning clothing bag or hand off to a friend or family member.
- Temperatures can still be cool for the beginning of the bike, but most athletes do not elect to wear gloves or arms warmers.
- As the day progresses there is the potential for the weather to get very warm. During the run the shade and greenery make the Le P-tit Train du Nord section of the run more comfortable, while the village section can feel very hot.
- Be prepared for cool temperatures if you anticipate you will finish after sunset.
