Roll out of Anloo and follow the Loonerdiep river before the Balloërveld nature reserve opens up around you. The route then crosses the Gasterse Duinen and slips through the Strubben-Kniphorstbosch, all before looping back to Anloo. It's 64.8 km with 64 m of climbing, and most of it runs unpaved, so expect a mix of surfaces under your wheels as the landscape shifts from reserve to reserve.
