The Borderride 400 begins in Epen, located in the Dutch province of Limburg. It challenges riders with a route of approximately 400 km, tracing the outer border of the Benelux region. As a component of the Grenspalenklassieker series, it caters to bikepackers seeking an ultra-distance challenge over a shorter sportive. Participants can select either a road or gravel configuration, with the option to complete the course across two days or in a single, extended day.
The course crosses border country, incorporating a blend of gravel tracks, MTB paths, and paved roads. The one-day version is noted to be around 370 km with approximately 6,000 meters of elevation gain. Bram Tankink developed the route and has been present to greet participants. The majority of riders opt for the two-day format, while the single-day riders commence their journey before sunrise at 5 AM. De Grenspalenklassieker organizes the event. YouTuber Douwe Doorduin has documented the ride, offering insight into its demanding, self-supported nature.
