The triathlete's training bible by Joe Friel Summary

1. Periodize your season with base, build, and peak phases to maximize race-specific fitness.
2. Master swim technique using Friel's four-step framework: Posture, Distance, Length, Catch progression.
3. Apply polarized training—80% low intensity, 20% high intensity—to boost endurance without burnout.
4. Prioritize muscular force training with big-gear workouts to build cycling power and prevent injury.
5. Schedule key "anchor workouts" first each week while balancing stress and recovery periods.
6. Eat 80% whole foods (meat, fish, vegetables) and limit starchy carbs to post-workout recovery.
7. Maintain performance after 50 with strength training, strategic recovery, and anaerobic capacity work.
8. Structure brick workouts as swim → run → bike to preserve technique and reduce injury risk.
9. Use Training Stress Score (TSS) to quantify workout load and track fitness progression accurately.
10. Develop year-round speed skills through high-cadence drills and technique-focused swim/run sessions.
11. Boost VO2max early season with short anaerobic intervals even for long-distance triathlon prep.
12. Align workout specificity with race demands using the "train like the race" principle in peak phase.
