Spain - Circular route

Hello Fellow Cyclists, How does a cycling adventure in Spain sound?  I am planning a trip of 4-6 weeks starting in June from Santander (Ferry from Plymouth), across the North coast to Dono Sebastian, skirting the Pyrenees to Zaragoza, then Teruel (possibly follow some of the Montas Vacias for a few days), then following the Camino Del Cid back to Burgos and finally back to Santander. The trip dates are flexible, aiming to start mid-June until July. On paper, the route is approximately 1200km. It would be good to have some company to share this experience, either the full journey or part of it. There are lots of options to join at various stages. I’m 62, retired, and a regular mtb/road and cycle tourer.  I like to stop for coffee/cake (these taste so much better with friends). I am looking at a mix of camping, hostels, and hotels, in the region of 30-50 miles per day (50-80km). Not looking to set any goals, just to enjoy my retirement and the journey. The average temperatures are in the region of 25 – 30C Don’t hesitate to get in touch to discuss further if this is of interest to you. Kind regards David
