I think Henao not going too win a GT he is overestimate. It exist alot of better colombian riders. Winning volta colombia isn't a really big thing. Yes it has alot of mountain stages. But the opponents in that race is not that hard. Henao has just turn 23 and by then you must have shown more talant too win a GT.
Sarmiento, Quintana, Beltran, Betancour, Duarte, Uran Uran and Rubiano have all alot bigger chance too be new colombian star rider.
