For the first time since 1992, the Vosges, Jura, Pyrenees, Central Massif and Alps regions will all feature in the same edition of the Grand Tour.
Team Sky rider Froome, a three-time Tour champion, is ready for another challenge, but believes there are also opportunities.
“I think, like every time, it’s a very tough route. There are not a lot of kilometres of time trial, only 23 kilometres and the prologue,” he said.
“But there are only three arrivals at the top of a climb. It will be a more aggressive race.
“There will be many chances to attack. I think it will be a good show.”
Froome said being consistent throughout the Tour, which will run July 1-23 next year, was crucial.
“The Tour de France is always tough. You need to be strong in the mountains, you need to be strong in time trial, you need a strong team, and you need to be strong during three weeks, not only one or two,” he said.
“You have to be strong everywhere, this is the Tour de France.”
