Every training plan is built specifically to use within the TrainingPeaks desktop apps, iOS app, and Android app. During purchase you will be asked to login or create a free account to start your training.


This 12-week base plan is the same as the 10.0-12.5 hour base plan except that it includes two days of strength training per week. There is a recovery week every third week with reduced training and a full day off from training. The recovery week and day off are very important in the schedule as they allow you to rest and repair, keeping you healthy and in good spirits

Sample Day 1

Run with heart rate in zone 1-2. Don't force zone 2. Flat to gently rolling. Continually check form. Quick cadence (88+ rpm).

Sample Day 2

Rolling hills seated

Ride primarily at 1-2 zones on a rolling course. Mostly in saddle on hills to build & maintain hip strength. Small and big chain rings.

Sample Day 2

AA Tri

Equipment: Either free weights or machines. Can be done as a circuit.
Load/Resistance: The greatest load possible for 20-30 reps per set (do not sacrifice good form for added weight--always estimate on the light side)
Sets: 2-3
Reps: 20-30
Recovery between sets: 60 seconds.
Important: During recoveries stretch muscle group just worked before starting next exercise.
Speed: Slow to moderate emphasizing perfect form
Progression: Complete one set of each exercise in order (1, 2, 3, etc) before starting second set. The first set every workout is the lightest (warm-up set). When you can complete 3 sets of 30 reps, increase load.
