Organised for more than 30 years by Ballooning Adventure, the^{François I Trophy} is a friendly competition starting from emblematic places in the Sologne. Places frequented at the time by François I, King of France from 1515 to 1547.

For a few years now, the Belgian Balloon Club has been participating, this year with no less than five crews.

With take-offs from different places every day, from Blois to Chambord, via Cheverny and Valençay, among others, pilots and passengers are amazed for a week.
