The details of this unrivalled ride

Event details

Flatlands 300 is a fixed route, A-to-B, single-stage, supported gravel ultra through the impressive green outdoors of the Netherlands. 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 timed 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, food and a bit of dancing.

Distance: 300 kilometers

Terrain: Mixed gravel and tarmac

Elevation: 1,200 meters of altitude

Start / Finish

Start - Landgoed Mariahoeve in Papenvoort (Drenthe) will be the starting location of this year's Flatlands 300. Registration will be at the main entrance of the camping site, where there will be limited parking place.  Camp spots are available for Friday night to start your adventure with a great outdoor camp experience. Further details can be found in the Logistics section.

Rider briefing will take place around the campfire on Friday evening. There will be no additional briefing in the morning as we want to respect the other guests of the camp site with our early start. 

Finish - The finish in Lage Vuursche will have catering (included in the entry). This is available for registered supporters as well. Parking is available at the finish location. Camping after the finish is not included, but a camping site including shower (De Zeven Linden) is located close to the finish location. Reservations need to be made on own initiative and expense.

The terrain

Flatlands 300 is a mix of fine crunchy gravel roads and backroads through the hidden gems of the Dutch countryside. The province of Drenthe offers you some of our infamous flint roads and heathlands that you will cross early on during your ride. You will ride across several natural sites that show rich wildlife and impressive panoramas. The forest sections tend to be pretty adventurous with a mix of speedy gravel on hard pack surfaces and double track sectors that bring you deep into the forests. Dont forget the funky shell paths, these are too much fun to not include in our route. Last but not least, hills. Maybe we have some, maybe not. Either way we are Flatlands 300, you can be sure you won't be served mountains.
