Is Olivier Coupat back?

Olivier Coupat, the Pole France coach , showed to the orienteering world that he had some power left , during the District Championships in Trondheim.
David Andersson won the race, 12" before Thierry Gueorgiou. Olivier came at the 8th place , 2:38 after Andersson, beating some orienteering big names.

After a good cross country skiing season, Olivier, 36 years old, had some good performances in orienteering, beating some french team runners.

Is he back or is it just a training for the cross country skiing season??
And what's his secret ?
