2026 Antwerp Marathon - Oct 18 Countdown

Q: How do I register for the 2026 Antwerp Marathon?

Sign up on the official site at antwerpmarathon.com/en/registrations. Entry is open first-come, subject to availability with no lottery or qualifying time. Marathon pricing is tiered by how many people have already entered, starting at &euro;95 for the early band and rising in steps (&euro;105 / &euro;115) up to &euro;130 once more than 6,000 runners have registered, so signing up early is the cheapest option.

Q: Is the Antwerp Marathon course flat?

Yes. The course is genuinely flat, with only about 85 m of total elevation gain spread across a 0-17 m range and no real climbs. The marathon covers two loops through central Antwerp on paved streets and riverside quays, which is why organizers and runners describe it as a fast PB course.

Q: What landmarks does the Antwerp Marathon pass?

The route is a city-centre tour taking in Zaha Hadid's striking Port House (Havenhuis), the grand shopping street De Meir, the cathedral-like Antwerp Central Station, and the trendy Het Zuid district, before a spectacular finish beneath the MAS museum on the banks of the River Scheldt.

Q: How hard is the Antwerp Marathon?

It is one of the easier major-city marathons to run a fast time on, thanks to the flat profile and cool October air. The main challenge is mental rather than physical: the two-loop format means you pass familiar ground twice, and damp wind off the Scheldt can feel raw, so pace discipline on lap one pays off on lap two.

Q: What should I wear for the Antwerp Marathon?

Dress for a start temperature near 12&deg;C (54&deg;F) with around 82% humidity and a chance of rain. Most runners are comfortable in shorts and a long-sleeve or short-sleeve top once moving. Bring a cheap throwaway layer or rain shell for the 9 a.m. corral, and apply anti-chafe given the likely damp conditions.

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

The cutoff is 5.5 hours (an average of about 7:50 per kilometre). By police order the roads reopen to traffic at this pace; runners going slower may be asked to stop or continue at their own risk on open roads. This generous limit makes the race friendly to first-timers as well as PB hunters.

Q: Is the Antwerp Marathon a Boston qualifier?

Yes. The TREK Antwerp Marathon is run on an accurately measured, certified course, so a finishing time here is valid for Boston Marathon qualifying (and other races that require a certified result). The flat layout makes it a strong choice if you are chasing a BQ standard.

Q: How big is the Antwerp Marathon?

About 5,500 runners started the full marathon in 2025, part of a record fifth edition with roughly 19,800 participants across all distances (marathon, half marathon and 10K). That makes the full-distance field mid-sized: large enough for a great atmosphere but without the multi-hour corral waits of the World Marathon Majors.
