Plan Description

“Maximise your training time with specific indoor optimized sessions that will keep your training fun and your improvements ongoing!”

Training plan description: Do you train indoors the majority of the time? Are you looking to be competitive in local group rides or smash your Strava records by the springtime (8-12 weeks after starting this plan)?

This training plan is designed for indoor smart trainer training which means sessions are designed to be specific and interesting so that you stay mentally fresh and motivated for the entire plan. Training sessions are compacted into 1-hour sessions in the workweek and 1-1.5 hour sessions on weekends (rides can be extended in time if you do them outdoors). The plan is designed in 2-week build blocks followed by an easier week before starting the next block. The first two blocks have a subthreshold, fat-burning focus. Subsequent blocks include specific training designed to improve your threshold power, V02 max, and then finally take you to peak form. This is achieved by always keeping the weekly hours around 5-6 hours/week for indoor training while increasing the intensity/TSS on build weeks. You may choose to head out on the road on weekends and push the weekly hours up to 8-9 hours/week. Group rides and endurance rides are given as alternatives.

The training is with Power and is designed in the Workout Builder format which provides your personalized power zones in each training session which are calculated automatically from your Threshold number inputted under settings. Additional benefits of the Workout Builder format include direct training session sync to your Garmin or Wahoo device and training session upload to Zwift, TrainingRoad, CycleOps and more.

Designed by former professional and multiple national champion coach Simon Kessler of Simon Says Cycling, coach Simon has coached for 25+ years and has enjoyed an incredible track record as a coach which includes state and national champions on multiple continents in the road, track and mountain biking. Some of Simon’s clients have won world championship medals and gone on to wear the yellow jersey in the Tour de France. With this plan, you receive 30+ years of top-level experience in a super effective training plan that will lead to fast improvements.
