38mm tyres enough for this Dolomites route?

Planning to ride this 5-day Komoot collection:

https://www.komoot.com/collection/1034963/finding-freedom-in-the-dolomites-5-days-bikepacking

About 400 km and 12,000 m climbing.

Has anyone here done this exact route?

I’ll be on a gravel bike with max 38 mm tyre clearance, running tubeless. Light hotel-to-hotel setup.

Is 38 mm enough for the terrain, or will I regret not running 42 to 45 mm?

How rough are the gravel and descents in reality?

Also open to other Dolomites gravel route suggestions if you’ve got better options.

Would appreciate any first-hand experience.
