91.2 km biking

The first time in my life I biked 91 km. Of course I had a flat tire at km 47. The hardest part was km 75-80. I really had absolutely no intention to go further. However, somehow kilometer added to kilometer and I just did it. By the way in an awful time of 05:10 hours. The course was hilly, agreed. Nevertheless the Swiss 70.3-Ironman bike-course will be hilly, too. So it will be exciting, if I make the biking in time.
