just saw a youtube video from Sports Uni of Cologne folks on two methods for making endurance rides more effective. Since I got scolded here for linking videos above a certain length just a high level summary (well … and the video is in German anyway):
-
priming (in the first part of the ride): https://physoc.onlinelibrary.wiley.com/doi/full/10.14814/phy2.12864
-
sprints during a ride (Weber/Lorang)
They speak of 2h endurance rides
