How to Train for Triathlons With Shorter Pool Distances

Maximizing Every Lap — How to Build Open Water Readiness in a 20- or 25-Yard Pool

You don’t need a 50-meter Olympic pool to train for triathlon success. In fact, most age-group and masters triathletes train in short-course yards (25-yard) or even shorter pools (20 yards, hotel pools, or community centers). And while these tight spaces present challenges — constant turning, limited pacing, no open-water simulation — they also offer unique advantages: more wall work, higher stroke turnover, and the chance to build explosive power.

The key? Adapting your training with purpose. With smart planning, you can turn a cramped pool into a launchpad for open water confidence, endurance, and speed.

In this guide, we’ll show you how to simulate triathlon demands, build race-specific fitness, and develop open water skills — all within the confines of a short pool.

🌊 Why Short Pools Aren’t a Limitation — They’re an Opportunity

Challenge	Strategic Advantage
Frequent turns	Build wall speed, streamline, and underwater dolphin kicks — critical for open water sighting turns
Limited distance	Force high stroke turnover and pacing discipline — mimics crowded swim packs
No open water	Use drills to simulate navigation, drafting, and race starts
Crowded lanes	Train in chaos — just like race-day conditions

“My athletes train in a 20-yard pool. They all say, ‘Coach, the open water feels endless!’ That’s because they’ve mastered efficiency in the short game.”— Triathlon Coach, 10+ years

🛠️ 7 Strategies to Optimize Short-Pool Triathlon Training

1. Simulate Open Water Pacing with “Broken” Sets

Since you can’t swim 1,500m straight, break it into race-realistic segments.

✅ Example (Olympic Distance):

• 6 x 250y = 1,500y  

  • Rest: 15–20 seconds between

  • Focus: Negative split each 250

• Mimics: Swimming in a pack with brief respites at buoys

🎯 Cue: “Race pace isn’t one speed — it’s controlled effort with micro-recovery.”

2. Master Wall Efficiency for Open Water Turns

In open water, you turn around buoys — but the push-off power is the same.

✅ Drill:

• Turn + 3 Stroke Sprints:

  • Push off wall → 5 underwater dolphin kicks → 3 powerful strokes → stop

  • Build: 8–10 x per session

• Goal: 10–12m underwater per wall

💡 Why it works: Buoy turns require explosive push-offs — short pools build this habit.

3. Practice Sighting Every 4–6 Strokes (Even in Short Pools)

You don’t need distance to train navigation.

✅ How to do it:

• Pick a target on the pool deck (water bottle, sign, coach’s hat)

• Sight every 4–6 strokes — lift eyes just enough to see (“alligator eyes”)

• Advanced: Sight on every 3rd stroke to simulate choppy water

🎯 Cue: “Sight, breathe, glide — don’t stop.”

4. Train Drafting in Tight Spaces

Crowded lanes = perfect drafting practice.

✅ How to do it:

• Swim 6–12 inches behind a partner’s hip or feet

• Focus: Matching stroke rate, reducing effort

• Sets: 4 x 100y — draft first 50, lead second 50

💪 Energy Savings: Drafting reduces effort by 15–20% — critical in triathlon packs.

5. Use Tempo Trainer for Stroke Rate Control

Short pools encourage choppy strokes. Fix it with rhythm.

✅ How to do it:

• Set Tempo Trainer to your goal stroke rate (e.g., 85 SPM for 1500m)

• Swim 100y sets matching the beep

• Goal: Same stroke count per 25y — no rushing

📏 Triathlon SPM Guide: Sprint (750m): 88–95 SPM Olympic (1500m): 82–88 SPM Half/Full: 78–84 SPM

6. Build Wetsuit-Specific Fitness

Most triathletes wear wetsuits — which changes buoyancy and stroke.

✅ How to do it:

• Swim 1–2x/week in your race wetsuit

• Focus:

  • Shorter, faster kick (legs float higher)

  • Relaxed breathing (neck seal awareness)

  • Streamlined breakouts

⚠️ Safety: Never skip wetsuit practice — chafing and panic are real race-day risks.

7. Simulate Race Starts in Tight Spaces

No diving blocks? No problem.

✅ How to do it:

• “Step-In Start” Drill:

  • Stand in 3–4 ft of water

  • On “Go!” → step forward, dive, 5 underwater kicks

  • 8 x 25y

• Goal: Clean entry, fast breakout

🎯 Cue: “Step, dive, glide — no splash.”

📅 Sample Weekly Short-Pool Triathlon Plan (25-Yard Pool)

Day	Focus	Workout
Mon	Technique + Open Water Skills	4 x 50y sighting every 4 strokes; 8 x 25y drafting
Wed	Endurance + Pacing	6 x 250y broken (15s rest); negative split each
Fri	Speed + Transitions	8 x 25y step-in starts; 6 x 50y wetsuit sprints
Sat	Race Simulation	1 x 1500y IM order (60 x 25y); T1 run after

✅ Total Swim Volume: 2,500–3,500y/week — ideal for triathletes

💡 Pro Tips for Short-Pool Success

• Count strokes, not just yards: “18 strokes/25y” is more valuable than distance

• Use fins sparingly: Only for technique drills — not endurance sets

• Train off the blocks: Even if you start mid-pool, practice wall push-offs

• Film yourself: Short pools make video analysis easy — check body position

🚫 Avoid: “Junk yards” (mindless laps) Skipping sighting practice Ignoring wetsuit acclimation

🧠 Mental Strategies for Short-Pool Swimmers

• Reframe turns as buoys: Every wall = a race marker

• Visualize open water: Imagine blue water, buoys, and a clear line to T1

• Embrace the chaos: If your lane is crowded, treat it like a mass start

💬 Mantra: “Short pool, long focus.”

💬 Real Triathlete Insights

“I trained in a 20-yard hotel pool for 6 months. At my first tri, the 1500m felt like a vacation. I passed 20 people on the swim.”— Sarah, Age 32, Sprint Tri Finisher

“My coach made me do 100 wall push-offs a week. At the buoy turn, I exploded while others coasted. That’s how I won my AG.”— Mark, Age 45, Olympic Distance Podium

Final Thoughts

Your pool size doesn’t define your potential. It defines your creativity.

With intentional training, a 20-yard pool can build the same open water confidence, pacing discipline, and wall speed as a 50-meter basin. In fact, the constant turning may even make you more prepared for the dynamic, unpredictable nature of triathlon swimming.

So stop wishing for a longer pool.Start maximizing the one you have.

Because the water doesn’t care how long the lane is —it only cares how ready you are.

Turn fast. Sight smart. Swim free.

Your triathlon swim success isn’t limited by space —it’s expanded by strategy. 💙🏊‍♂️🚴‍♀️🏃‍♂️
