Yes offcourse he will have to manage his efforts. But the last years the break is often very big so you don't waste much energy there if all teams are represent. Jumbo sent a lot of guys in front last year so UAE will copy that. But it's Mathieu, even in the Giro with bad legs he spent to much time in the wind. Just wanna see him with a good prep there, win some stages and be ready for the Worlds. That's his main goal, apart from finishing the Tour.I could see UAE and Jumbo making the race hard on some of those medium mountain stages so it might be unrealistic to think the early breaks will make it. If he is always jumping in breaks that get caught that will wear him down and take away some of his explosiveness, no? But I don’t think I know his stage race history well enough to know for sure.
