The weather forecast was promising with partly sunny skies and temps near +20°C. I didn't prepare for this event very well, as I just didn't want to. My only goal was to have a nice day in the saddle and enjoy the familiar route. As there was those 3 service points, I didn't even take anything to eat with me. Just one bottle of water. I was also a little late for the start but the plan was to ride my own speed so it didn't bother me at all.
The first service point is at 48 km, so I knew that I would have a little hard time after the first hour of riding. And yeah, I was not far away from bonking, but I slowed my pace just a little and managed to reach the service point fairly comfortably. The service points are pretty primitive, containing only salt cucumber, bread and juice. But that is just enough to have some energy to keep going, so no problem here.
After this things went smoothly. I knew that the next two service points weren't far away, and I would survive. I was riding with too low energy levels for sure, and my pace wasn't fast, but hey, I didn't come here to rip my legs.
I can't simply praise the route enough. I have already a plan for the future to ride with a lots of breaks and take hundreds of photos.
My road bike after the ride. The front wheel is from my time trial bike as the inner tube of the original wheel was broken.

As shown above, my heart rate was very low because of the low energy level, and riding still felt pretty tough. But I enjoyed it all the way!
