The Norwegian ace, IRC champion in 2010, is in third position, 4.3s behind leader Sepp Wiegand after two stages.
He said: “These have been one of the two most difficult gravel stages I’ve ever done. They are very twisty and slippery and I didn’t have so much confidence with the grip to push, so I didn’t push at all.”
Mikkelsen has opted to run on hard-compound tyres for the afternoon loop of stages although he has taken two soft compound tyres in the event of damp conditions. Wiegand will continue on soft compound tyres only.
