Patrick asked in a comment to provide more detailed information about equipment and nutrition. I like doing it of course. There will be more about nutrition in the coming days. Now first about the “hardware”:
I ride a Cervelo S3 with Shimano Ultegra 11-speed and disc brakes (160mm). All pretty standard. In addition a set of custom made carbon wheels with 50mm rim height and DT Swiss 350 straight pull hubs from FarSports. If it is very windy at the start, I will possibly swap the wheel set, and install the standard set with a lower rim height (HED Ardennes Plus GP Disc). There is also a Power2Max power meter and a 20 € cheap aero stem, that feels heavier than the rest of the bike. The pedal system is from Speedplay and the stem ist from FSA SLK light, tyres from Conti Grand Prix 25mm.
My computer is a Garmin Edge 530. It has a long battery life and is charged by a power bank (10000mAh) while driving. The power bank also supplies my smartphone with which I can also navigate. The power bank is in the bag on the stem, the smartphone on the bag.
The saddle bag is from Ortlieb (Seatpack L) in which bars, powdered drinks, and of course a rain jacket and warmer clothes are stowed for the night and the early hours of the morning. You see some tape at the saddle post to prevent scratches fro the saddle bag. Not nice, but useful.
I mount 3 LED taillights, one on each strut, one on the saddlebag. In the front a China beater, i.e. a bright LED lamp for light. Plus a headlamp on the helmet. I also have a reflective jacket for the night. Security is the most important thing.
That all. You don’t need much, and less is actually more …
