Tony Martin has taken the national title in the time trial for the ninth time in a row and the tenth time in total.
The German from Jumbo-Visma completed the course over 30 kilometers between Öschelbronn and Gäufelden the fastest.
The 36-year-old Martin was almost a minute faster than the number two, Martin Miguel Heidemann of Leopard Pro Cycling.
In 2010, Martin captured the German championship jersey for the first time in the time trial.
A year later he had to give that title to Bert Grabsch, but after that Martin was always the best in this part.
Last year the national championship was not held due to the corona crisis.
Martin, four-time world time trial champion, is part of the Jumbo-Visma Tour team.
He will ride the Tour in the service of the leaders Primoz Roglic and Steven Kruijswijk.
The Tour de France starts its thirteenth Tour de France next Saturday in Brittany.
He won five stages, three of which were time trials.
His teammate Tom Dumoulin won the Dutch time trial title in Emmen on Wednesday.
