Olympic Triathlon Brick Training: 10 Essential Sessions
Summary
Olympic brick training blends Zone 2, tempo and threshold efforts to prepare your body for strong run performances off the bike. These 10 essential sessions target intensities between 68–93% of max heart rate, 56–105% FTP and RPE 4–8. Each workout builds endurance, pacing control and transition speed — key elements for Olympic-distance triathlon success. Whether you're focusing on aerobic strength, race simulation or quick turnover, these bricks will help you train smarter and race faster.
Why Brick Training Matters for Olympic Triathlon
Brick training — combining two disciplines back-to-back — is critical for building endurance, efficiency, and mental toughness on race day. Olympic-distance racing demands more than just swim, bike, and run skills — it demands the ability to transition efficiently and maintain pace under fatigue.
Brick workouts train your body and mind to handle the unique demands of switching disciplines, improve your endurance under race conditions, and optimize your pacing strategies. Structured brick sessions are a crucial component of preparing for a fast, confident race day.
These 10 key brick sessions will help you master the bike-to-run transition, sharpen your race fitness, and give you the edge you need!
