I think Kajsa had injury problems before switching to Tregaro – not a bad move in my mind. The problem was having surgery too late into the training year (spring 2004), thus having insufficient time for recovery/training for outdoors. Surgery should be done in the fall if possible. In this case, they kind of knew she had problems from the previous summer but still tried to manage throug this year. Obviously it failed and a total rupture of her achilles tendon became reality. Btw. Viljo Nousiainen (the coach of Patrik Sjöberg) used to coach both Olsson and Tregaro in their youth. I think Tregaro is using the same concept/philosophy as Viljo did.
