I really enjoyed the ride from Bordeaux to Agde in 2014. Its a great ride out of Bordeaux NOT on the canal but a converted ex-railway line tarmacked as only the French can. Includes a well lit tunnel, vineyard views and ends in a nice medieval town in time for lunch. The Garonne was fine apart from the tarmacked towpath undulating due to the plain tree roots so speeds need to be modest for comfort.
Toulouse is best done with a SatNav as you leave the canal. The problem is getting in the right lane ahead of the signposting. Onwards is fine and occasionally spectacular until Ocean Lock. Leave the canal there and don't be tempted back. Besides which the roads I used were not busy and a pleasant change from towpaths. There are some lovely towns and villages to eat and drink.
If you are a lazy cyclist - this is the tour for YOU!
