Race guide

Slachtemarathon returns in June 2028, not 2027

The point-to-point format makes transport a central part of preparation. The start and finish are in different villages, so wait for the next edition’s bus and parking plan before choosing where to leave a vehicle. Older pickup locations and wet-weather parking changes describe their own edition.

The running category is listed at 42.195 km, while the walking route and programme are presented separately. Check that your entry is for the timed running event if that is your goal. A walking ticket or a separate Freonenkuier announcement does not confirm participation in the full running marathon.

The grass and soft-ground sections can feel different from the paved parts, particularly after rain. Prepare for the confirmed surfaces and avoid assuming that a dike route is uniformly smooth road. Follow traffic controllers at road and railway crossings and do not try to recover time through an unsafe crossing.

The organizer combines the route with village culture, music and performances. Supporters should use the official access plan and keep the running course clear, especially around narrow passages and the finish in central Raerd. The long lead time until 2028 is useful for building consistent training, but it does not require beginning a peak marathon block now. Wait for the exact day, registration and participant guide before scheduling a final taper or making race-specific travel commitments. Confirm aid, personal-support rules and the finish limit when they are published; none can be established merely from the month announcement. Keep the older course description as preparation context and recheck it against the final 2028 map, including any changes to the soft-ground sections or transport arrangements.
