This plan is designed to prepare you physically and mentally to race every leg of the race — swim, bike, and run — so you can cross the finish line stronger and faster than ever.
.
Our 44-week training plan starts with a focused 12-week base phase, then builds into a 32-week targeted program tailored for the unique demands of the Half Distance Triathlon Boulder. Whether you’re new to triathlon or stepping up your training game, this plan will develop your endurance, power, and technique.
.
Here’s how this plan will transform your race day performance:
.
✅ Efficient Base Building — The first 12 weeks lay a solid foundation with swim drills, strength training, and endurance workouts that improve your fitness without burnout.
.
✅ Advanced Endurance and Speed Work — After the base phase, training intensifies with VO2 interval sessions, anaerobic threshold workouts, and race-specific brick workouts to build stamina and speed.
.
✅ Course-Specific Preparation — Tailored workouts reflect the Boulder Reservoir swim, the rolling bike course with fast descents, and the fast, two-loop run on packed dirt and pavement.
.
✅ Technique and Strength Focus — Instructional swim videos enhance your efficiency and reduce injury risk, setting you up for a smooth, powerful race day.
.
✅ Heart Rate and RPE Guided Workouts — Each run and bike session uses Rate of Perceived Effort and heart rate zones to optimize training load and recovery.

Why This Training Plan Works for Boulder
.
Boulder’s Half Distance Triathlon swim features cool 62°F water and a counterclockwise course. The bike demands power and pacing over two loops of rolling terrain with a thrilling descent. The run tests your ability to maintain speed over two fast, rolling loops on dirt and pavement.
.
Our plan prepares you for these conditions by emphasizing swim technique in cooler water, building the strength and endurance for those short rollers and descents on the bike, and training for fast, efficient running on varied surfaces.
