From summitpost:

Picos de Europa is a mountain range near the north coast of Spain. The "El Anillo Picos de Europa" is a circuit of about 110 km (for the largest, "Three Massif" ring) linking numerous huts/refugios in the range and National Park.

Admin note: So far reported FKTs go to Point Lenana at 4985m, which is the common “trekking” summit. The true high point is Batian, 5199m, but it is difficult technical climbing to reach the summit. If anyone is aware of FKTs to Batian, please let us know.

Toubkal (4167m) is the highest peak in Morocco.  Trekkers usually approach the mountain from the road-end village of Imlil. For experienced mountaineers, guides are not required for the normal route, as it is a moderate hike and orientation is not a problem.

Scholtenpad is a collection of paths centered on the city of Winterswijk in the Netherlands, basically a large loop with 4 "spokes".  The outer loop makes a logical route of 75 km. Info and GPS tracks here:  https://www.gpstracks.nl/wandelroutes-law.php?id=4735
