Our son ran the VDLP while we walked it. He accompanied us for about 300 km and ran anywhere from 30-37 km daily. Keep in mind you arrive at your destination early, your accommodation may or may not be open yet, and some places are small and don’t have much entertainment. (Though we have walked the coastal from Porto and found the places to be a bit bigger than along the VDLP for the part our son ran). He had a 20 LTR pack.
If you want I can ask him if he minds his details being shared. He’s not in this forum. After 11 days he said he was glad not to have to run for a few days!
. I wonder why…
Hope this helps
