Online Riders Meeting

Before Flatlands 300, there will be an online riders meeting where we will share everything you need to know. You'll have the opportunity to ask any questions. We'll cover the event schedule, route details, bike equipment, and practical information to get to the start. The exact date will be announced soon.

Briefing on event

Saturday evening, Gijs Bruinsma, the so-called "Route Director," will share all the essential information you need for Ultra Day. And remember: it’s not a race!
