Immortal Doc finished sixth in this year's Prix d'Amérique, with a taste for more.
Now the six-time millionaire is once again being prepared for the world's toughest trotting race.
"We're aiming for it, but he's not in form yet," says Fredrik Wallin ahead of Wednesday's start on V86.
He won the Swedish Championship in superb style, and most recently he put on a show despite a tough trip.
On Saturday, Svarte Petter is back on V85® and will be the favorite to win again in the double jackpot at Bergsåker.
"The horse feels at least as good as when he won the Swedish Championship, and he's clearly my best chance," says trainer Henrik Svensson.
