Racking up as many kilometers as possible as a cycling team over a period of 21 days – that was the challenge accepted by 55 Fraunhofer IZM employees in September 2021. They swapped cars and trains for more self-propelled means of transport and covered no  less than 16181 km, winning them a very respectable 28th place in the competitive ranking. »Stadtradeln« is a Germany-wide initiative that wants to get people out of their routines and onto their bikes: 80 percent of all German households own bikes, but rarely  use them. What better occasion than doing so for a team effort? Every cycled kilometer can be tracked in a dedicated app, and routes can be recorded for later (anonymous) analysis by the Technical University of Dresden. The findings can be used by local  authorities to optimize their cycling infrastructure and slowly improve the situation of cyclists in Germany.
