Auch wenn neben Beruf und Familie nicht viel Zeit für andere Interessen bleibt, versuche ich zum Ausgleich zur Büroarbeit wenigstens eine zusätzliche Sache zu machen, und das ist Rad fahren. Ab und zu nehme ich auch an Rennen in meiner Umgebung teil (bis September 2001 war das Hamburg, seit Oktober 2001 ist es Würzburg). Nachfolgend aufgezählt ein paar meiner Ergebnisse:
