Race Day Weather

Average Temperature	10.1°C / 50°F
Humidity	78%
Wind	27.3 km/h
Rain Chance	55%
Typical Conditions	Late-October on the Niagara River sits around 8C (46F), with highs near 13C and cool single-digit lows at the 8:15am start. Skies are often overcast and a steady parkway headwind is the course's signature challenge.

What to Prepare: Dress for a cold start you can shed - arm sleeves and throwaway gloves over a singlet. Pin the bib low so a parkway crosswind can't flap it, and bank nothing on the early downhills; save energy for the exposed final miles into the wind.

Wind Impact on Race Day

Wind at 27.3 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.

Frequently Asked Questions

When is the 2026 Niagara Falls International Marathon?

The 2026 Niagara Falls International Marathon is Sunday, Oct 25, 2026, with the full marathon starting at 8:15am EDT on Fallsview Boulevard and finishing beside the Niagara Falls Convention Centre on Stanley Avenue. The 10K and half marathon run the same morning.

Is the Niagara Falls Marathon a Boston qualifier?

Yes. The course is measured and certified by Athletics Canada and AIMS, so finish times are valid for Boston Marathon qualifying. It is one of Canada's flattest, fastest BQ-hunting courses. Check your target with our Boston qualifying calculator.

How flat is the course - is it good for a PR?

Very. The route runs almost entirely along the Niagara River Parkway with a gentle net-downhill profile and only minor undulations, making it a genuine PR course. The one variable is wind: long, exposed stretches can deliver a steady headwind. Model your splits with our pace calculator.

Does the marathon still start in Buffalo and cross the border?

No. The historic cross-border format that started in Buffalo and crossed the Peace Bridge ended after 2021. Since 2022 the entire course runs within Canada along the Niagara River Parkway, so you no longer need to clear a border checkpoint mid-race.

What is the course time limit?

The course closes at 3:00pm, giving marathoners roughly 6 hours 45 minutes from the 8:15am start (about a 9:35/km or 15:25/mile average). An early cutoff requires reaching the 3.5km mark by 9:00am, and it is strictly enforced.

How much does it cost and how do I register?

The full marathon is open online registration (no lottery) through Race Roster, with tiered pricing that rises toward race day - roughly CA$150 in spring 2026, climbing past CA$170 by autumn. Registration closes Oct 7, 2026, with no race-day signup.

What's the weather like in late October?

Expect cool, often overcast conditions: around 8C (46F) at the riverside start, warming toward 13C by midday. It is close to ideal racing weather, but pack a throwaway layer for the chilly start and plan for a possible parkway headwind in the final third.
