This 24-week Half Distance Triathlon training plan is built to get you ready for the specific demands of racing in Les Sables d’Olonne. Every phase of the program is designed to help you train with purpose, progress steadily, and arrive at the start line confident and well-prepared.
.
🔥 Before You Begin
In week one, you’ll complete a 25-minute anaerobic threshold session. To get the most out of this plan, you should already be comfortable finishing an Olympic distance triathlon and have a solid aerobic foundation.
.
âś… Swim Prep That Matches the Course
You’ll work on open water skills like sighting, drafting, and beach starts—essential for navigating the point-to-point canal swim that begins in front of Les Atlantes. The swim sessions help you stay relaxed and efficient in real race conditions.
.
âś… Build Power for the 91 km Bike
The bike course has 600 meters of climbing through forest, coastal roads, and rural terrain. Your plan includes hill intervals, tempo rides, and threshold work to help you manage the course with strength and control.
.
âś… Brick Workouts to Nail the Run
You’ll train to run well off the bike with structured brick sessions that reflect the flat 21.1 km course along Les Remblai. We’ll also prepare you for varied surfaces, including a short section on the beach.
.
âś… Smart Progression
You’ll follow a 3:1 structure—three weeks of building, followed by one week of recovery. This keeps your training productive without tipping into fatigue.
.
âś… Focus on Key Metrics
Run and bike intervals target aerobic endurance, threshold, and VO₂ max. Each session has a clear purpose, so you know exactly what you’re improving.
.
âś… Train With a Plan, Peak at the Right Time
You’ll start under 10 hours per week and gradually build to a peak of 18 hours. The progression is designed to match your fitness curve and taper you into race day ready, not worn out.
.
âś… Refine Form, Reduce Risk
Swim drills and AI-supported run gait analysis help you fine-tune technique and stay injury-free as volume increases.
