Hendricks said the race was hard and the heat played a big role.
“There were lots of wind and I think that was the big factor that decided the race.
“Myself and Chris Jooste managed to make the front split and from there we had a few attacks and split up again.
“With 60km to go I made a solo attack and a small group came across to me. From the group I just tried to survive.
“We finished on a category one mountain and I just tried to keep my tempo and make my way up the climb. I managed to hold off the rest of the guys and took sixth.”
Hendricks also took sixth place in the Fenkil Northern Red Sea Challenge the previous day.
He, along with the rest of the South African national road cycling team, will be competing in the Tour of Eritrea from tomorrow.
