Nouvelle Aquitaine is one of the products of the recent re-organisation of French territories into larger administrative regions. It was created by merging three former regions: Aquitaine, Poitou-Charentes and Limousin.So, last week we had the Tour du Limousin - Nouvelle Aquitaine. This week - starting tomorrow - we'll have the Tour Poitou - Charentes en Nouvelle Aquitaine.
The Nouvelle Aquitaine region does not want to have their own bike race, but they'll happily share hosting rigths with neighbouring regions.
While the regions may have been reorganised, however, the départements within them have not, so the upshot of this is that Poitou-Charentes and Limousin no longer exist as administrative entities, but the départements that were part of those regions still host the bike races in the area that previously existed as regional races, but both are tours of (no longer extant, but easily definable) sub-entities within Nouvelle-Aquitaine.
