2026 Cologne Marathon - Oct 4 Countdown

Q: When and where is the 2026 Cologne Marathon?

The Generali Köln Marathon takes place on Sunday, October 4, 2026, with the full marathon gun start at 10:30 a.m. (the half marathon starts earlier at 08:30/09:00). Runners start on Opladener Straße next to Bahnhof Deutz / Ottoplatz and finish on Komödienstraße directly beneath Cologne Cathedral.

Q: How do I register and what does it cost?

Entry is first-come, first-served — there is no lottery. Register online at the official Generali Köln Marathon site. The standard full-marathon fee is &euro;130; early-bird tiers sell at lower prices and rise toward &euro;130 as slots fill, so sign up early. Registration closes once the field is full, so do not wait for race week.

Q: How flat is the Cologne Marathon course?

Very flat. The course climbs only about 36m in total (with a 31m descent) and has a high-to-low delta of roughly 10m across the full 42.195km. That makes it one of Germany's faster big-city marathons and a strong choice for a personal record.

Q: Is the Cologne Marathon a Boston qualifier?

Yes. The course is officially measured and a full AIMS member run on closed roads, so finish times are accepted for Boston Marathon qualifying and other championship entries. You do not need a qualifying time to enter Cologne itself — entry is open.

Q: What is the time limit?

The full marathon has a 6-hour net time limit. The streets must reopen to public transport afterward, so a sweep (broom wagon) follows the final runners. That works out to roughly an 8:32 min/km (13:44 min/mile) average pace to finish inside the cutoff.

Q: What weather should I expect in early October?

Expect a crisp autumn morning: a low near 6&deg;C (44&deg;F) around the 10:30 start warming to a high around 15&deg;C (59&deg;F). Humidity averages about 82% and there is roughly a 32% chance of rain. These are near-ideal racing temperatures — dress light but carry a throwaway layer and a thin rain shell.

Q: How big is the full-marathon field?

The full marathon draws roughly 7,900 finishers — a mid-sized, very runnable field. Including the half marathon and relay teams, the wider event hosts tens of thousands of participants and a lively, well-supported atmosphere through the city quarters.

Q: What's the easiest way to get to Cologne?

Fly into Cologne Bonn Airport (CGN), about 15 minutes from the city center by train, or use Düsseldorf Airport (DUS) roughly 45 minutes away by direct train. Cologne's main station (Köln Hauptbahnhof) sits beside the Cathedral finish, and the city is a major hub on Germany's high-speed ICE rail network. Most travellers from outside the EU should check whether they need the new ETIAS travel authorization, which the EU is rolling out from late 2026.

Wind Impact on Race Day
