Ken Block has described the stages on Rally Argentina as some of the hardest he will ever drive on.
American Block is making his return to the world championship in South America after missing the last two events in Jordan and Italy following the birth of his third child, a son Mika.
"The second stage on Friday, is probably the roughest, most difficult stage you've ever been on," said the Monster World Rally Team pilot. "They are just incredible stages, a bit like Portugal with turns over crests. But they vary a lot more and are very unique."
Block hasn't been at the wheel of his Ford Fiesta RS WRC since a heavy crash during shakedown for Rally of Portugal in late March, which put him out of the event prior to the start.
"I've focused a lot of time in the past week with my preparation," said Block. "Being away from the car and the events for so long I really wanted to be prepared when I got back so I'm feeling the way I did after the first two runs in Portugal before the crash."
