Sprint Triathlon

Welcome to Triathlon

The sprint triathlon is the perfect introduction to multisport racing. With a 750m swim, 20km bike, and 5km run, it's challenging but achievable for almost anyone willing to put in the training. This plan assumes you can swim continuously for 10 minutes, bike for 30 minutes, and run for 20 minutes.

The Multisport Mindset

Triathlon training is fundamentally different from single-sport training. You're not just building fitness in three disciplines—you're learning to manage fatigue across sports, master transitions, and develop mental flexibility.

Swimming: Focus on technique over intensity. Swimming is the most technique-dependent of the three sports. Smooth, efficient swimming conserves energy for the bike and run.

Cycling: The bike leg is where you set up your run. Push too hard and you'll pay on foot. Ride smart, stay aero when possible, and fuel consistently.

Running: This is where races are won or lost. You'll be running on tired legs—practice this with brick workouts (bike immediately followed by run).

The Four Phases

Foundation (Weeks 1-3): Establish consistency across all three sports. Most sessions are easy effort focused on building comfort and technique. You'll swim 2x/week, bike 2x/week, run 2x/week.

Development (Weeks 4-7): Add interval work in each discipline. Swimming includes 100m-200m repeats. Cycling adds tempo intervals. Running incorporates threshold work. Weekly volume increases gradually.

Integration (Weeks 8-9): Introduce brick workouts (bike-to-run sessions) that simulate race-day fatigue. Practice transitions. Dial in race-day nutrition and gear choices.

Taper & Race (Week 10): Reduce volume by 40%, maintain some intensity, and arrive at race day fresh and confident.

Training Principles

Transitions are the fourth discipline: Practice setting up your transition area at home. Rehearse your swim-to-bike and bike-to-run changes. Seconds add up.

Brick workouts matter: Running off the bike feels completely different. Brick sessions teach your legs to adapt to this unique neuromuscular demand.

Technique before intensity: Especially in swimming, prioritize smooth form over hard effort. A technically sound swimmer will beat a fit but inefficient swimmer every time.

Train the weakest, maintain the strongest: If you're a strong runner but weak swimmer, dedicate extra time to swimming without sacrificing run fitness.

Race Day Strategy

Swim Start: Position yourself appropriately. Don't start at the front if you're a slower swimmer—you'll just get swum over. Find clear water and swim your own race.

First Transition (T1): Take your time. A calm transition is faster than a frantic one. Focus on getting your gear on properly—wet feet and rushing lead to mistakes.

Bike Leg: Start conservatively. Your legs will feel great initially—don't overcook it. Stay aero, fuel early and often, and prepare mentally for the run.

Second Transition (T2): Your legs will feel heavy—this is normal. Walk if needed in transition. Focus on getting your run shoes on and starting smoothly.

Run Leg: The first 400-800m will feel strange. Your legs are learning to run after cycling. Stay patient, let your stride come to you, and finish strong.

The Sprint Triathlon Promise

Your first triathlon will be unlike anything you've experienced. It's chaotic, exhilarating, challenging, and deeply rewarding. You'll discover capabilities you didn't know you had. Trust your training, embrace the adventure, and enjoy becoming a triathlete.
