Plan Description

“Increase your fitness and power with this 12 week indoor specific base building plan"

This 12-week base training plan is designed to help you make big improvements in leg strength, pedaling efficiency, endurance and threshold power. The plan is designed for indoor training on Zwift (or TrainerRoad and other training apps) with specific sessions including personalized power targets and workout cues. Your day's training is loaded automatically each day into Zwift under "training". Just press start to begin your session. Your day's training session also syncs automatically with newer Garmin and Wahoo bike computers.

Training plan description: The goal of this training plan is for you to build a strong base of fitness and great threshold power with just 12 weeks of focused and highly effective training. This training plan works great for cyclists who can fit in 5 days/week of training, with typically 60-90 minutes available Tuesday, Wednesday, Thursday, and 1.5-2.5 hours available on weekends for indoors (can be increased to 3-5 hours for outdoor riding). The plan builds with 3-week training blocks followed by an easier week before starting the next 3-week block. A weekly VO2 max session is scheduled weekly with the remainder of the training targeting below threshold training to increase your base (lots of sub threshold, tempo, big gear etc). You have the option to include a Zwift race or group ride 1-2 times/week (noted in the plan). Before starting the plan you should have a good level of fitness and be accustomed to training 4+ hours/week.
