The Team Sky rider is nearly three minutes ahead of his closest rival, Tejay van Garderen, as the peloton heads into stage 12 in the Pyrenees.
"I'm in a great position at the moment and have a great team around me," the Kenyan-born rider told teamsky.com.
"The best thing for us is to ride defensively now and try and follow the other contenders. The other teams need to make things happen and there's a big battle going on for the GC positions. Guys were jumping around trying to get time on each other today, and we're certainly expecting a big battle out there tomorrow [Thursday]."
Froome added that he is expecting general classification contenders Alberto Contador and Nairo Quintana to try hit back on the slopes of the Plateau de Beillie, which boasts gradients of up to 8%.
"I've reconned that stage and the summit finish at Plateau de Beille is brutal, similar to yesterday's stage,' added the 2013 Le Tour winner.
"We're expecting Quintana and Contador to attack, and I'll play things how I see it out on the road."
