The 300 km gravel ultra
of The Netherlands.
Flatlands 300 is a fixed route, supported, A-to-B, single-stage gravel ultra through the impressive green outdoors of the Netherlands. Starting just after sunrise and finishing just before sunset, you will ride across the deepest forests and the wildest heathlands, following our route that is unofficially certified as #FlatAsAPancake. And though it's not a race, your adventure will be tracked and dotwatched since we all ride with one mission: finish on time to join the Finishers Fest to end the day in festive vibes with friends, drinks, and delicious food.
