Erkner logistics: getting there from BER, where to stay, and what to check before you register

Erkner is a small town on the south-eastern edge of Berlin, in Brandenburg, sitting on the Dämeritzsee. On paper the logistics look simple: airport nearby, the capital on your doorstep, a compact race. But there are two unknowns to deal with right away: date confirmation and a lack of verified official details.

First things first: the date

Sources disagree. One says September 12, 2027; another says the next date hasn't been announced yet. Bottom line: don't book anything non-refundable until the official website confirms. One source lists an organizer contact: erkner70.3@ironman.com. Email them if you have questions about the date or registration.

Getting there

The nearest airport listed in the sources is Berlin Brandenburg (BER). Erkner sits in south-east Berlin: S-Bahn and regional train connections exist, but schedules and frequencies should be checked closer to the date, especially for race weekend. If you're driving with your bike, keep in mind that Erkner's town center is small and road access will be restricted on race day: arrive the day before and check the organizer-designated parking.

If you're flying with a bike box, plan the transfer from BER: information on any official shuttles isn't available in the sources consulted, so budget for a taxi, rental van, or a regional train with your bike, checking the bike transport rules first.

Where to stay

No verified official hotels appear in the sources. Two strategies. First: stay in Erkner or its immediate surroundings to cut race-morning travel to zero; but a small town's accommodation sells out fast. Second: stay in south-east Berlin and travel by train or car; more choice and more flexible pricing, but you need to test-run the route the day before. Either way: book early with a cancellable rate, given the uncertainty around the date.

Transition and the race

The swim starts from the Strandbad in Erkner, on the Dämeritzsee; the town center is close to the run course. The exact logistics — transition locations, bike check-in times, spectator areas — aren't available in the sources consulted and should be verified on the official website and in the athlete guide once it's released.

Family and spectators

For anyone coming along, the race is spectator-friendly: the run is a multi-lap course through the town center, with plenty of spots to catch you going by without moving, between the market square and the Gerhart-Hauptmann museum. The lakeside lido and the proximity to Berlin offer options to fill the day. Give your family a fixed spot and estimated split times for each leg.

Registration and costs

Entry fees aren't available in the sources consulted. For pricing, registration opening dates, and terms, check the official website or the email contact listed above.
