Last day before the first rest day in the HTV Cup, and with that in mind we got a somewhat surprising BOTD consisting of Phạm Quốc Cường, Erdenebat Bilguunjargal and Igor Frolov. As you can imagine, a break including such strong riders and indeed GC threats was not allowed much rope and Lộc Trời chased them down coming in to the first intermediate sprint to prevent them gaining any bonus seconds, instead allowing the ever-vigilant Võ Thanh An to gain a few, as well as Nguyễn Văn Bình taking 2 seconds to extend his lead in the U23 classification. In the end, the always aggressive Bilguunjargal joined the next move, but Vinama settled for Nguyễn Minh Việt rather than one of their two leaders in a large group also including Huỳnh Thanh Tùng and Trần Lê Minh Tuấn. They gained about a minute before exploding attacking one another before the second intermediate, and while they made it to the sprint unhindered, the in-fighting cost them most of their advantage.
While some of the break were able to re-establish a lead, none of the most key GC names were involved even though Nguyễn Hữu Đức was just 43" behind; they were well under control. The last escapees were caught within sight of the line, although the long, wide finishing straights here make that sound more dramatic than it actually was. Trần Tuấn Kiệt took his second stage in a row, while once more the Lộc Trời boys took advantage of time bonuses to extend their lead, Quàng Văn Cường taking 2nd and Nguyễn Tấn Hoài 3rd respectively.
