( CNN ) -- Corinna Schumacher , wife of the stricken motor racing legend Michael , has issued a personal message of gratitude to Formula One fans ahead of this weekend 's German Grand Prix at Hockenheim . Writing in the official race program , Schumacher thanked motorsport fans for their `` good wishes and positive energies '' sent to the former racing driver who was critically injured in a skiing accident in France at the end of last year . `` The German Grand Prix gives me the perfect opportunity to cordially thank you all for the good wishes and positive energies you keep sending to Michael , '' Schumacher wrote . `` I have to say your sympathies literally blew us all away ! Good to know that together we made it through the hardest time ! '' Last month , Schumacher 's agent Sabine Kehm said that the seven-time world champion was no longer in a coma and had been transferred from the French hospital in Grenoble , where he had been recovering from a severe head trauma , to University hospital in Lausanne , Switzerland to `` continue his long phase of rehabilitation , '' a statement from Kehm said . Schumacher 's statement was printed in both German and English topped by a photograph of a smiling Schumacher with an inset image of the couple together . `` Now we are facing a phase which will presumably take a long time . `` We trust that -- as for so many years in F1 -- time will be Michael 's ally in this fight . Until then I would like to wish you and your families all the best as well . '' The couple have been married since 1995 and have two teenage children -- daughter , Gina Marie and son , Mick . Hockenheim was a happy hunting ground for Schumacher who won his home Grand Prix four times at the circuit -- once for the Benetton-Renault team and three times for Ferrari .
