"Time will tell," he said. "If I lose the race by one second, I'm going to wish I eked out another second here. But I'm ahead of any time bonuses, so as long as I stick to the wheel (of my rivals) I'll be safe in that regard, and Bernal has shown he's going uphill really well."
Van Garderen's lead should be safe on Friday's fifth stage, a flat 110-mile trek from Stockton to Elk Grove that should be decided in a sprint. But the crucial test will be the following day, when the peloton tackles a long, brutal stage that ends with a hard climb in Lake Tahoe.Bernal will no doubt attack. So will Daniel Martinez, who is just 37 seconds off the overall lead, and a host of other climbers with aspirations of snatching away van Garderen's yellow jersey.
"Tahoe is going to be a big test of the strength of the team, and I think we have one of — if not the — strongest teams here," van Garderen said.
"They'll be able to control it and when we get to the upper slopes of the climb, I'm going to have to stick to the climbers."I'm no scrub when it comes to altitude," he added, "so I think I should be able to handle that."
