Application Scenario:Application Scenario:Assisted TrainingAssisted Training
• Training group of 4 or more (racing) cyclists• Given track profile
• Cyclists have different qualities regarding the track sections• Each cyclist has a given overall physical condition and
an individual training plan • Training effect depends on the speed of the group and the position of
the cyclist within the group formation
Track Section
Uphill
Even
Downhill
Maximize the training effect of each cyclist during group training!
