Thanks for the update about the race.
Those Mongolian riders are hard as nails, I've heard stories and even seen video footage of them training on the roads in Mongolia during the winter with -20 to -25 °C.
Do you have a link where I can find the route of the race (it's not exactly the most easy race to follow)?
Frolov is interesting, he pretty much only does low intensity training rides and then pulls some really wild performances out of his hat when he's competing.
Just look at his powerdata from the stage of the 5 Rings of Moscow he won last year. 338W normalized power for 3:47:50 while being 63kg light, no additional comments needed...
I don't think stage profiles or anything like that are available. However, the race Wikipedia page (in Vietnamese) has some good details, such as the Start List and Race Route.
For the route, the word "Vòng" indicates a circuit and "đèo" is a mountain pass. The the stages with mountain passes are 9, 12, 18, 20 and 22. There are links to the Wikipedia pages of the better known climbs. I believe only Stages 18 and 20 have peaks approaching 1,000 m.
If you're interested watching, HTV airs the full stages live and posts in their YouTube page. Full stages, 25 min per stage highlights and shorter 8 min per stages highlights are all there. Stage = Chặng.
