Hi Neil, the late starting vacation time of our kids does not allow so we won't meet at O'France. Do you happen to go to Soriška for OOcup this year? (entries still open, until today...)
Height: if you have a GPS only watch, no surprise, the Z is rather poor given the triangulation. Or do you have a pressure-based one?
GPS had more trouble with X and Y in the gorge today, unsurprisingly.
I seem to be running out of energy for traversing Europe (beyond the upcoming French adventure), so I'll likely head to Ireland reasonably soon after...
