38,41 km cycling route from Castéra-Verduzan to Mirande

After sampling the calcium-, magnesium- and sulphur-rich thermal waters of the Castéra-Verduzan spring called La Renaissance, time for you to ride on rejuvenated to the more conventional waters of the Baïse River. The cycle route leads you through bucolic hills, past typical Gers bastide settlements, up to Mirande. In the commune, or parish, of St-Jean-Poutge, the Château de Herrebouc is worth pausing at, especially as the slope just after it is quite challenging; climbing steeply up a hillside, our cycle route does though offer beautiful views over the valley. Past Brouilh-Monbert, hardier cyclists can head on to the little city of Auch (capital of the county of Gers) via a parish road, the C8. For an easier time, continue on to L’Isle-Noé. At the confluence of the Petite Baïse and (Grande) Baïse Rivers, this lovely village boasts a château, a public garden and… a rugby ground, reflecting the iconic sport in these parts. Finally, you arrive at Mirande, the Gascon bastide par excellence, divided up into a grid pattern of 49 identical plots of historic houses.

The Route

On this stage, the cycle route sticks wholly to parish and county roads. 
Watch out for the left turn off the D939 road towards the Château de Herrebouc. There are a few short stretches along the D939 road between St-Paul de Baïse and Saint-Jean-Poutge and before Le Brouilh-Monbert where you need to keep focused and stay well to the right.

Shortly after Brouilh-Monbert, a link that at time of writing still isn’t signposted allows you to reach the little city of Auch via the C8 parish road. This link is only suitable for experienced cyclists, as it involves significant shifts in altitude and some very technically demanding descents on narrow tracks, the surfacing pebbly and bobbly, the slopes steep and the bends tight.
