As if an inaugural campaign in the World Rally Championship was enough of a challenge, former grand prix champion Kimi Raikkonen faces another at this weekend's Erzberg Rodeo, which culminates in the famous Red Bull Hare Scramble.

The Finn will go head-to-head with another Red Bull athlete, multiple trials bike champion Taddy Blazusiak, this Saturday, pitting his familiar Citroen C4 WRC against the Pole's KTM trials bike, as they tackle 13km of dirt road up the side of a mountainside quarry. Around 1500 riders compete in the event over the course of the weekend, watched by more than 30,000 spectators.

It's a straightforward race from start to finish, and plenty of pride is at stake because the loser will have to wash the winner's vehicle. Raikkonen has never been scared to push himself to the limit, but the challenge he has set himself this time is an awesome one, as Blazusiak has been the Red Bull Hare Scramble champion for the past three years.

The Finn, by contrast, has contested only five World Championship rallies at the wheel of his Citroen C4 WRC. As usual, he will be co-driven by fellow Finn Kaj Lindstrom, while Taddy will tackle the course on his own.

"It should be a really interesting experience, although I really don't know what to expect," Raikkonen admitted, "I love bikes and I've got a few of my own, so I'm really looking forward to meeting Taddy and seeing the action. One thing I don't enjoy though is washing bikes, so I have to make sure that I win!

"Seriously though, it's going to be a nice challenge and I really don't know who can be quickest. I suppose it depends on what the course is like. I've seen some videos and it looks awesome. We're going to have a lot of fun this weekend."

Winning at Erzberg has special significance for Blazusiak, and he will be going all out to deny Raikkonen on Saturday.

"Erzberg is the race that started my career as an extreme enduro rider, so it is a very special for me," he pointed out, "Getting the chance to compete against Kimi in his rally car will be great. He's a great guy and a huge name in motorsport, so I'm honoured to be racing against him.

"I will be doing some testing this week in order to be as best prepared as I can be. I've been fortunate at Erzberg and have three wins now, so I'm looking to make that four. But anything can happen, as it's such a demanding and unforgiving place."
