Some pros might be relaxing or getting ready for the holidays this time of the year, but the fast German Sebastian Kienle spent time aero testing and bike fitting with gebioMized and STAPS. His 2018 Kona race did not go as planned and the 2014 Ironman World Champion is hungry for more speed. He even managed a shout out to slowtwitch forum members.
The devil is surely in the details. But what are you doing this winter? Eating donuts or getting faster?
