Falls Lake Recreation Area

This is a 7 mile mountain bike trail.  https://www.ncparks.gov/falls-lake-state-recreation-area/trail/mountain-bike-trail-%E2%80%93-south-loop

A single-track loop blazed with blue circles and also has 38 distance markers 400, 401,402,…,438 along the entire path. The trail is very hilly with a few flat sections.

The Abbey Line Trail takes the scenic route between Watford Junction Station and St Albans Abbey Station, or either end of the Abbey Line railway route. The route also links to stations in between. The Trail is way-marked and places on the route between Watford and St Albans include Meriden, Colney Street, Frogmore and Park Street. About 9 miles one-way.

Dillenburg nach Brilon, 154,7 km with 3064m vertical

von Altenahr bis Bad Bodendorf, 35,6km with 1444m vertical
The Rotweinwanderweg is a 35 km walking trail that winds through the Ahr Valley (Ahrtahl in German) past hilltop ruins, countless vineyards, forests and open fields between the villages of Altenahr and Bad Bodensdorf. That said, you certainly don’t need to hike the entire route.

Start at the beginning of the Centennial Trail, just past the front gates of the park. Follow the Centennial Trail in its entirety, which brings you to the visitor centre parking lot. From here, just head to the road and go all the way to the most southern point in all of Canada. The Tip! Go as far as you can without getting your feet wet, take a picture and then take the same way back to the start.  About 20km, basically flat.
