I shouldn't complain, since the riders in the Tour are having a gruelling time in the heat, but here goes anyway. Breaking a bone in my left hand and the resultant plaster cast up to beyond the wrist (entirely due to my own stupidity by the way) has made all sorts of things impossible, difficult, or just plain uncomfortable. Gripe over, back to the Tour de France.
Today the race starts from one of France's most spectacular landmarks:
Pont du Gard.

The aqueduct was part of a 50km/30 mile system that brought water to Nemausus (Nîmes). It has a gradient of only 1 in 18,241 (!) but just enough to keep the water moving in the right direction.
The arms of the Commune
Vers-Pont-du-Gard seem to have nothing to do with the aqueduct, unless the pale lozengy or and gules perhaps refers to the mortar-free stone-work.

The route proceeds North-East through
Rochefort-du-Gard whose arms are very similar to Vers-Pont-du-Gard (so perhaps the stone-work idea was rubbish!).

Pedalling on, the riders pass
Saint-Romain-en-Viennois whose arms, featuring an heraldic dolphin, were granted only in 2017 (though they may have been in use unofficially long before that).
Why a dolphin? As far as I can tell, the town has no link with Dauphiné or the Dauphin of France. Nor does Saint Romain, who came from the Jura in Switzerland, have anything to do with dolphins. Quite wrong. The "Viennois" in the town's name should have been a clue. The Dauphiné is also called Dauphiné Viennois. So the heraldic dolphin in the arms is indeed to signify Saint Romain's inclusion in Dauphiné.

Immediately before turning North for the last push to the finish, the riders traverse the village of
Valserres whose population is only around 200 and perhaps therefore may be forgiven for having an advertisement for a coat of arms.

The blazon says that the charge is "au naturel" (proper) thus circumventing the tincture "rule".
The finish is at
Gap (not the clothing store), whose arms feature not a castle but a "portail de ville" (city gate), or is it a "château donjonné de quatre tourelles"? Two sources, two blazons.
