JUNE HEATWAVE - What do you do?

The forecast predicts a 15 day heatwave, 30 degree averages in the north and 38 in the south. I think it's currently 25 degrees at 2pm on our 'cool' north facing terrace in the shade, so it's too much for me to be in the sun - my tolerance level is lowering yearly.
So what do you do? Well firstly walking is transferred from an afternoon to morning activity, many French run walking groups set off at 8.30 am, I am a morning(ish) person but that's definitely not for me - happy to get out of bed early, but I like to ease my way slowly into the day.
So it was to be a 10am kick off for our rando yesterday, but the OH emerged from bed with the glad tidings we had to wait in for a parcel delivery, how I curse internet shopping.
Reschedule - 3pm departure.

All in all it did not go as expected, my knee was playing up again - always does after a gardening session, we missed our first turn off, and it was quite warm, so the length was curtailed.

Anyway. The walk started in Langlade quite a nice hameau, yet another place that falls into the category of 'a nice place to visit but I wouldn't want to live here', for the usual reason of its about a 15 minute drive to get bread and milk, further for anything else and should you meet anything coming in the opposite direction on the road, I for one would be reduced to a quivering puddle of tears as I don't do reversing and the edge of the road has the tendency to disappear off down a mountain precipitously.
For the second day in a row we were accosted by some locals en route, looking for - not a lost dog this time but 2 lost donkeys, such is life in the Languedoc.  

We followed the GR
