But now came a 6 km singletrack that I have ridden before, but in the other direction. I was glad I took the bike with the susp.fork because there where huge roots ( about 25cm/10 inch high :))and large holes. This trail lead to the Kaiser Wilhelm Tower. For the first time after 25km I crossed a road. I stayed on top of the mountain for another 2 km, then went into a long downhill. It started with 2 kms of forest road, the came another 4 km of small singletrack. Well, here in Baden-Wuerttemberg, the south western state of Germany, riding on trails smaller than 2m is forbidden. Since my tires are 2.1 m wide, I am allowed to ride on every trail that fits under my tire! ;)
After this great downhill I had to go all the way back on a forest road, I.e. 500m elevation. I started getting tired because I didn't do any serious traning in the last three months, but I managed to do it. When I crossed the road again I thought that I only had to go down to my car, but after the next turn came another 150m of elevation. Finally I reached the entrance to the last downhill, the first part was another typical Schwarzwald singletrail with lots of baby-head-rocks and sandy ground which murders chain,brakes and rims. But today it was perfectly dry. The second part was a 70 Km/h forest road. I rode back to my car and was satisfied with me, but very exhausted.
I have done 53km with about 25 km of singletrack,1300 m elevation, in exactly three hours.
