2026 P'tit Train du Nord Marathon - Oct 4 Countdown

Q: How do you register for the P'tit Train du Nord Marathon?

Entry is first-come, first-served through the official site - there is no lottery. The field is capped and sells out: the 2026 marathon and half-marathon are already sold out with no waitlist. Registration typically opens in December the year before. The full-marathon entry fee is $145 CAD (2026), with an optional $25 refund-protection add-on; standard registration is otherwise non-refundable.

Q: How much elevation does the course drop?

The course is a net 220m downhill (over 700 ft), running point-to-point along the old railway line from Val-David down to Saint-Jerome. GPS data shows roughly 179m of total climbing against about 400m of descent, so it is one of the gentlest profiles in North America. findmymarathon ranks it the #1 fastest marathon course in Canada.

Q: What is the course like underfoot?

The route follows the P'tit Train du Nord linear park, a converted rail bed that is hard-packed gravel with short asphalt sections. It is smooth, wide, and shaded by Laurentian forest for most of its length - closer to a fast cinder track than a technical mountain trail. Wear road shoes or light trail shoes; spikes and aggressive lugs are unnecessary.

Q: Is the P'tit Train du Nord Marathon a Boston qualifier?

Yes. The course is certified and Boston-eligible, and you do not need a qualifying time to enter. The downhill profile delivers an unusually high success rate: 15.2% of finishers qualified for Boston in 2025 and 18.8% in 2024, which findmymarathon ranks among the top BQ-rate marathons in Canada.

Q: How hard is the race and how should I pace it?

It is one of the easiest big marathons to run a personal best on, but the relentless gentle downgrade quietly hammers your quads. The biggest mistake is going out too fast on the free speed. Run the first half controlled, save your legs for the final kilometers into Saint-Jerome, and do downhill-focused training beforehand to blunt quad fatigue.

Q: What is the time limit and how do shuttles work?

The marathon starts at 8:00 am with a 5.5-hour cutoff (a required pace of about 7:50 per km at checkpoints). Because it is point-to-point, you finish in Saint-Jerome, so most runners park there and take the shuttle bus to the Val-David start ($10, ~35 minutes; first bus 6:30 am, last bus 7:30 am, reserve by Aug 30). Beyond the checkpoints there are no further on-course services for runners off the pace.

Q: What should I wear for race-day weather?

Dress for a cool, possibly wet Laurentian autumn. Early-October mornings average about 9&deg;C (48&deg;F) with overnight lows near 5&deg;C, and rain falls roughly one day in three. A singlet or short sleeves plus gloves and a throwaway top for the start line works well; the forest holds humidity around 80%, so a light packable shell is smart if showers threaten.
