2026 Baystate Marathon - Oct 18 Countdown

Q: When is the 2026 Baystate Marathon and what time does it start?

The 2026 Baystate Marathon is on Sunday, October 18, 2026 in Lowell, Massachusetts. The full marathon starts at 8:00 a.m. Eastern Time at the Tsongas Center in downtown Lowell, with the half marathon and relay starting alongside it. It is held on Columbus Day weekend, a popular fall-marathon slot in New England.

Q: Is the Baystate Marathon a good Boston qualifier?

Yes — it is one of the best Boston-qualifying courses in the Northeast. The course is flat, USATF-certified (course MA10634JK), and consistently produces a very high qualifying rate: about 22.9 percent of finishers ran a Boston-qualifying time in both 2024 and 2025, and 24.7 percent in 2023. That is why it attracts a serious, time-focused field. Check your own target on the Boston qualifying calculator.

Q: Is the Baystate Marathon course flat?

Yes, it is genuinely flat and fast. The full marathon is a double loop along the Merrimack River with only about +154 m (507 ft) of total elevation gain across the whole 26.2 miles — no real hills, just gentle river-valley grades and a few bridge approaches. It is built for fast times, which is part of why it is so popular with runners chasing a personal best or a Boston qualifier. Use the race time predictor to set a realistic goal.

Q: How big is the Baystate Marathon and is the full marathon still offered?

Yes, the full 26.2-mile marathon is offered alongside a half marathon and a half-marathon relay. The full marathon is a mid-sized regional race: about 1,140 runners finished the full in 2025 and 1,078 in 2024, making it one of the larger New England marathons but still far from a big-city crowd. The smaller, focused field is part of its appeal for qualifiers.

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

The full marathon has a 6-hour course time limit from the 8:00 a.m. start. Official course support and the finish line shut down 6 hours after the gun; runners still out after that are asked to move to the sidewalks to finish. That works out to roughly a 13:44 per mile (8:32 per km) pace to make the cutoff — manageable for most, but the relatively tight limit reflects its time-focused field.

Q: How do I register for the Baystate Marathon and what does it cost?

Registration is handled online through RunSignup via the official Baystate Marathon page; there is no lottery — entry is first-come, first-served until it fills. The full marathon fee is around $120, with prices rising as race day approaches, so registering early saves money. The event is run by the Greater Lowell Road Runners, one of the few major marathons still organized by a volunteer running club rather than a for-profit company.

Course Profile

Course Type	Double loop (start and finish at the Tsongas Center)
Elevation Gain	154m
Terrain	Road (flat paved riverside roads and bridges, double loop)
Profile	A genuinely flat, fast course built for fast times — this is one of the reasons Baystate is among the most popular Boston-qualifying races in the Northeast. Runners start and finish at the Tsongas Center in downtown Lowell and complete two identical loops along paved roads beside the Merrimack River, crossing several bridges and dipping briefly into neighboring Chelmsford and Tyngsboro before returning. Total elevation gain is minimal, only about +154 m (507 ft) spread across the whole double loop with no real hills, just gentle river-valley grades and a few bridge approaches. It is USATF-certified (course MA10634JK) and a Boston qualifier, and it delivers: roughly 22.9 percent of finishers ran a Boston-qualifying time in both 2024 and 2025, one of the highest BQ rates in New England, which is why it draws a serious, time-focused field. The double-loop format means you see the same scenery twice and pass the start/finish area at halfway, which some runners love for the crowd lift and others find mentally tough on the second lap.
