Olympic Triathlon Training Guide 2025: Your Complete Roadmap to the Standard Distance

1. Introduction to Olympic Triathlon

The Olympic triathlon—also called Standard distance—is the flagship format of multisport racing. Featured in the Olympic Games since Sydney 2000, this distance represents the perfect balance between sprint racing intensity and endurance challenge. At 1.5km swim, 40km bike, and 10km run, it's demanding enough to require serious preparation but accessible enough for dedicated amateur athletes.

What makes the Olympic distance special is its requirement for true all-around fitness. You can't fake your way through 40km on the bike or a 10K run on tired legs. This distance rewards consistent training, smart pacing, and the mental fortitude to push through the inevitable tough patches in each discipline.

Whether you're stepping up from sprint distance or targeting your first triathlon at this level, this guide provides everything you need for a successful Olympic triathlon experience.

2. Understanding the Distances

The Standard Format

• Swim: 1,500 meters (1.5km or 0.93 miles) - approximately 25-40 minutes for most athletes
• Bike: 40 kilometers (24.8 miles) - approximately 1:00-1:30 hours for most athletes
• Run: 10 kilometers (6.2 miles) - approximately 45-70 minutes for most athletes

Time Breakdown by Level

Note: These times include transitions (T1 and T2) in the total time. Transition times typically range from 2-5 minutes each for age-groupers.

3. Prerequisites: Are You Ready?

Before starting a dedicated Olympic triathlon training plan, you should have a solid fitness foundation. This isn't a beginner-level event, and jumping in unprepared risks injury and a miserable race experience.

Minimum Fitness Baselines

Swimming:

• Comfortable swimming 500 meters continuously without stopping
• Basic freestyle technique that won't break down over distance
• Experience swimming in open water or willingness to practice before race day

Cycling:

• Ability to ride 20+ miles comfortably
• Basic bike handling skills including shifting, braking, and cornering
• Experience riding in various conditions (wind, hills, traffic)

Running:

• Can run 5K (3.1 miles) without walking
• Running at least 3 times per week consistently
• No current injuries that affect running

4. Essential Equipment

Swim Gear

• Wetsuit: Essential for open water racing in most locations. Provides buoyancy and warmth. Budget $150-400.
• Goggles: Have two pairs—one tinted for sunny conditions, one clear for overcast. Practice with both.
• Tri suit: One-piece or two-piece suit designed to wear through all three disciplines. Padded but quick-drying.
• Swim cap: Usually provided at races, but practice with one in training.

Bike Gear

• Road or triathlon bike: Either works; tri bikes offer aerodynamic advantage but aren't necessary for your first Olympic.
• Helmet: Mandatory. Aero helmets provide slight advantage but standard road helmets are fine.
• Cycling shoes: Clipless pedals and shoes significantly improve power transfer. Elastic laces or speed laces for faster transitions.
• Flat kit: Spare tube, CO2 or pump, tire levers. Practice changing flats before race day.
• Hydration: Bottle cages on frame. Consider aero bottle between aerobars for tri bikes.

Run Gear

• Running shoes: Well-fitted shoes you've trained in extensively. No new shoes on race day.
• Race belt: Holds your bib number, allowing quick attachment in T2.
• Hat/visor: Sun protection and sweat management for the run.
• Elastic laces: Speed laces allow faster transition without tying.

Nutrition and Hydration

• Gels/chews: 2-4 gels for the bike leg, depending on your fueling strategy
• Electrolyte mix: For your bike bottles
• Race nutrition: Know what's provided on course and practice with it, or carry your own

5. 12-Week Training Plan Overview

This plan assumes you meet the prerequisites and can commit 8-12 hours per week to training. The plan progresses through three phases: base building, race-specific training, and taper.

Weekly Structure

Phase Breakdown

Weeks 1-4: Base Building

• Establish consistent training rhythm
• Build aerobic base in all three disciplines
• Practice basic brick workouts
• Weekly volume: 6-8 hours

Weeks 5-8: Race-Specific Build

• Increase intensity with intervals
• Build long bike up to 50+ miles
• Build long run up to 8+ miles
• Race simulation brick workouts
• Weekly volume: 10-12 hours

Weeks 9-10: Peak Training

• Highest volume weeks
• Full race simulation workout
• Practice race nutrition
• Weekly volume: 11-14 hours

Weeks 11-12: Taper

• Reduce volume by 30-50%
• Maintain some intensity
• Focus on rest and recovery
• Mental preparation and logistics

6. Swim Training for 1.5K

The 1,500-meter swim is typically the most intimidating leg for athletes coming from a running or cycling background. It requires dedicated technique work alongside fitness building.

Key Swimming Focus Areas

Technique Over Speed: In triathlon swimming, efficiency beats raw power. A smooth, sustainable stroke will serve you better than thrashing to the front only to be exhausted for the bike.

Sighting: Open water swimming requires lifting your head to navigate. Practice sighting every 6-8 strokes in pool training.

Drafting: Swimming behind or beside another swimmer saves significant energy. Practice swimming close to other swimmers.

Sample Swim Workouts

Workout 1: Technique Focus (2,000m)

• 400m warm-up (easy freestyle)
• 4 x 50m drill/swim by 25 (catch-up drill/regular)
• 4 x 100m at moderate pace, focus on smooth catch
• 8 x 50m with sighting practice every 6 strokes
• 400m easy cool-down

Workout 2: Race Pace (2,500m)

• 400m warm-up mixed strokes
• 6 x 200m at race pace, 30 sec rest
• 4 x 100m slightly faster than race pace, 20 sec rest
• 300m cool-down easy

Workout 3: Open Water Simulation (2,200m)

• 300m warm-up
• 1,500m continuous at race effort with sighting every 8 strokes
• 400m cool-down

7. Bike Training for 40K

The 40km bike leg is where you can gain or lose significant time, but it's also where pacing mistakes are most costly. Ride too hard, and your run will suffer dramatically.

Power and Pacing

If you have a power meter, target these zones for the bike leg:

• Competitive age-groupers: 75-85% of FTP
• Intermediate: 70-80% of FTP
• Beginners: 65-75% of FTP (conservative is smart)

Without a power meter, use perceived exertion. You should be able to speak in short sentences but not hold a conversation. The effort should feel sustainable for 40km, not maximal.

Sample Bike Workouts

Workout 1: Threshold Intervals (75 min)

• 15 min easy warm-up
• 3 x 12 min at 85-90% FTP, 5 min recovery
• 15 min easy cool-down

Workout 2: Race Simulation (90 min)

• 15 min easy warm-up
• 60 min steady at race effort (75-80% FTP)
• Practice nutrition every 20 min
• 15 min cool-down

Workout 3: Long Endurance Ride (2-3 hours)

• Mostly Zone 2 (easy aerobic)
• Include 2-3 x 10 min at race pace
• Practice all nutrition strategies
• End with 10-15 min brick run

8. Run Training for 10K

The 10K run is where Olympic triathlons are won or lost. Running on fatigued legs after swimming and biking is uniquely challenging—your body wants to stop, but you have 6.2 miles to go.

Key Run Training Principles

Build Gradually: Running creates the highest injury risk. Increase weekly running volume by no more than 10% per week.

Off-the-Bike Running: Your "fresh" 10K pace won't be achievable off the bike. Plan for 15-30 seconds per mile slower than your standalone 10K pace.

Negative Splitting: Start the run conservatively. It's far better to feel strong in the final miles than to blow up at mile 2.

Sample Run Workouts

Workout 1: Tempo Run (50 min)

• 15 min easy warm-up
• 20 min at tempo pace (comfortably hard)
• 15 min easy cool-down

Workout 2: Intervals (45 min)

• 10 min warm-up
• 6 x 800m at 5K pace, 90 sec jog recovery
• 10 min cool-down

Workout 3: Long Run (70-80 min)

• Easy aerobic pace throughout
• Include 4 x 30-second pickups
• Practice race-day hydration

9. Brick Workouts

Brick workouts—combining two disciplines back-to-back—are essential for triathlon training. They teach your body to transition between activities and prepare you for the unique sensation of running on tired legs.

Why Bricks Matter

The bike-to-run transition is notorious for making your legs feel like concrete blocks. This happens because cycling recruits different muscle fibers than running, and the sudden change catches your body off guard. Regular brick training adapts your neuromuscular system to this transition.

Progressive Brick Workouts

Beginner Brick (Weeks 1-4)

• 45 min easy bike
• 15 min easy run (don't worry about pace)

Build Brick (Weeks 5-8)

• 60-75 min bike with 20 min at race effort
• 20-30 min run starting easy, building to race pace

Race Simulation Brick (Weeks 9-10)

• 40km (25 miles) at race effort
• Practice T2 transition
• 30-40 min run at race effort
• Practice nutrition throughout

10. Transition Mastery

Transitions are often called the "fourth discipline" of triathlon. In an Olympic distance race, efficient transitions can save 2-5 minutes compared to fumbling through.

T1: Swim to Bike

The Process:

1. Exit water, start removing wetsuit from shoulders while running to transition
2. At your spot, pull wetsuit down to waist, then off legs (practice this!)
3. Put on helmet first (mandatory before touching bike)
4. Shoes on (or ride with shoes already clipped in)
5. Sunglasses on
6. Grab bike, run to mount line

Time-Saving Tips:

• Use Body Glide or cooking spray on wetsuit ankles for easier removal
• Elastic laces on bike shoes for faster entry
• Have everything laid out in order: helmet open and facing you, sunglasses on helmet

T2: Bike to Run

The Process:

1. Dismount before the line (feet out of shoes if comfortable)
2. Rack bike
3. Remove helmet
4. Change shoes
5. Grab race belt with number, hat/visor
6. Go!

Time-Saving Tips:

• Elastic laces on running shoes—no tying needed
• Race belt pre-attached so you just clip it on
• Practice slipping feet into shoes quickly

11. Race Day Execution

Pre-Race Timeline

• Day Before: Pick up packet, rack bike, check transition area layout
• Morning of: Arrive 90+ minutes before start
• Set up transition: Lay out all gear systematically
• Check bike: Tires inflated, nutrition loaded
• Warm up: Easy jog, dynamic stretches, brief swim if allowed
• Get wetsuit on: 15-20 minutes before start

Swim Strategy

• Start position: Beginners should start to the side or back to avoid contact
• First 200m: Stay calm, find your rhythm, don't sprint
• Main swim: Settle into sustainable pace, sight regularly
• Final 100m: Pick up effort slightly, prepare mentally for T1

Bike Strategy

• First 5km: Easy! Your heart rate is elevated from the swim. Settle in.
• Main ride: Find sustainable effort, stay aero when safe, eat and drink
• Final 5km: Reduce effort slightly to prepare legs for run

Run Strategy

• First 2km: Start conservatively! Don't chase people passing you
• 3-7km: Settle into target pace, stay mentally positive
• Final 3km: If you have anything left, now is the time to use it
