Started in Roncesvalles, stopped in Bizkarreta-Gerendiain for lunch and made it to Zubiri. Pretty easy hike but you need endurance. Some elevation gains. The downhill portion at the end was a little tricky with the uneven footing (like walking on rails). Took about 6.5 hours in total with the stops. Completed today in mid-October, so the weather was absolutely gorgeous (45 F at start to 65 F at finish). Lots of shade provided and sweet views of cattle, sheep, horses, mountains and towns. A bunch of towns available for the first 8 miles if you need to rest.
