You aim at good results in training for an endurance sport and try to improve your performance
level in training as you peak for the season’s main event with an upward trend.

These 3 week are relatively high in the intensity. If there is possible to add training session, those should be with low intensity training. If you feel hard to follow this program, consider leaving on tempo/ interval session out from the weekly program.

Adapt the training program to your everyday life by changing the session order. If you don't have any exercise background, cut the duration by 50%. Some of the sessions can be replaced with other activities i.e. cycling and swimming if there is background of injuries.

If this training plan looks too difficult to follow, check out the Suunto - 3 week Fitness Enthusiast Running plan.
