Experience on running and power maintenance (FTP)

Hey guys,

I’m not even a year into cycling but since the beginning I incorporated structured training (TR since January) into my routine. If there is one thing you start worrying about quite early then it is your FTP and the more specific power gains you earned so hardly on the trainer …

Due to my profession I’m forced to travel on a regular basis. Sometimes it’s possible to take my bike with me and sometimes it’s not. Are some athletes in this forum which have experience with running as a substitution over a course of 2- 3weeks? Did you notice major changes in bike performance?

Appreciate your thoughts.

Best regards form Cologne (Germany),
