2027 Buffalo Marathon - May 30 Countdown

Q: When is the 2027 Buffalo Marathon and what time does it start?

The 2027 Buffalo Marathon is held on Sunday, May 30, 2027 over Memorial Day weekend, with the full marathon starting at 6:30 a.m. ET in downtown Buffalo near the Buffalo Niagara Convention Center on Delaware Avenue. The half marathon and 4-person relay start the same Sunday morning, with 5K and family events on the Saturday. (The race traditionally falls on the Sunday of Memorial Day weekend; confirm the exact date once the organizer posts it.)

Q: How much elevation gain does the Buffalo Marathon course have?

Very little — the course climbs only about 585 feet (178 m) over the full 26.2 miles, with an almost equal amount of descent on this downtown-and-waterfront loop. There are no real hills; the route is flat and fast, which is exactly why it is so popular for chasing a PR or a Boston-qualifying time.

Q: What is the time limit for the Buffalo Marathon?

The official course time limit is 6 hours — with the 6:30 a.m. start, the course closes around 12:30 p.m. That works out to roughly a 13:44 per mile average pace. Plan your splits with our pace calculator to stay comfortably ahead of the cutoff.

Q: What does the Buffalo Marathon course look like?

It is a downtown-and-waterfront loop. You start near the Buffalo Niagara Convention Center, run out to LaSalle Park and about seven miles along the Lake Erie waterfront past the Erie Basin Marina, Canalside and KeyBank Center, then swing back through downtown by Niagara Square and the Art Deco Buffalo City Hall. The route then heads north to loop Forest Lawn Cemetery and Olmsted-designed Delaware Park before finishing back downtown. Scenery alternates between open lakefront and Buffalo's historic architecture.

Q: How do I register for the 2027 Buffalo Marathon?

Registration is handled through RunSignUp and is open to international runners with straightforward English-language online sign-up. Entry is first-come with tiered pricing that rises as race weekend approaches — the full marathon has run roughly $105 to $175 in recent years. Register early for the lowest tier; deferral and transfer windows typically close about a month before race day.

Q: What is the weather like for the Buffalo Marathon?

Late May in Buffalo is usually cool and comfortable for racing — a race-morning low near 52°F (11°C) warming to a high around 70°F (21°C), with a fresh breeze off Lake Erie on the waterfront miles. The early 6:30 a.m. start keeps conditions crisp; dress for a cool, breezy lakefront start and shed layers as the day warms.

Q: Where should I stay for the Buffalo Marathon?

Stay downtown near the start and finish around the Buffalo Niagara Convention Center, Delaware Avenue and Niagara Square — it puts you within walking distance of the 6:30 a.m. corral and the finish-line festivities. Downtown hotels fill up over Memorial Day weekend, so book early. Buffalo Niagara International Airport (BUF) is about a 20-minute drive east of downtown.

Course Profile

Course Type	City loop
Elevation Gain	178m
Terrain	Road (flat downtown streets and a long lakefront waterfront stretch, paved throughout)
Profile	A genuinely flat, fast city loop and one of the strongest Boston qualifiers in the Northeast. The course starts and finishes downtown near the Buffalo Niagara Convention Center on Delaware Avenue, then heads out to LaSalle Park and runs roughly seven miles along the Lake Erie waterfront — past the Erie Basin Marina, Canalside and KeyBank Center — before swinging back through downtown around Niagara Square and the landmark Art Deco Buffalo City Hall. From there it climbs gently north up Delaware Avenue to loop historic Forest Lawn Cemetery and the Frederick Law Olmsted-designed Delaware Park, passing the Albright-Knox Art Gallery, then returns down Delaware to the downtown finish. Total elevation gain is only about 585 feet (178 m) over 26.2 miles with no real hills, so it rolls almost imperceptibly. As a USATF-certified Boston qualifier it routinely sends a strong share of finishers to Boston — about 10.5% qualified in 2025 (10.3% in 2024) — making it a reliable flat-course PR and BQ destination. USATF-certified.
