:::chuckle::: Quinranda, the only people I know who find/found the Primitivo difficult either developed an injury, or were generally people like me, who did almost no hill training with a pack (plenty of walking, but not much under those conditions) prior to showing up. I'd also walked the last 114 of the Frances with pretty much ease two years prior, so I wasn't expecting the struggle. That's why I asked you about your Frances experience.
The Salvador, from what I read, is a bit more difficult than that, and it's not as well marked, so people like me who aren't comfortable with offline map navigation don't tend to do it.
*You* probably would have little to no trouble.
