Triathlon Wetsuit Swimming: Technique Adjustments Guide
Learn how to swim efficiently in a triathlon wetsuit. Technique adjustments, buoyancy benefits, and getting the most from your wetsuit.
Swimming in a triathlon wetsuit requires technique adjustments—higher hand entry, less kick, and modified body rotation—to take advantage of the added buoyancy.
A wetsuit can make you 5-10% faster, but only if you adapt your technique to work with the suit, not against it.
Wetsuit Benefits
Why Wetsuits Help
| Benefit | Impact |
|---|---|
| Buoyancy | Hips float higher, less drag |
| Reduced drag | Smoother surface than skin |
| Warmth | Comfort in cold water |
| Confidence | Psychological security |
| Speed | 5-10% faster typical |
Who Benefits Most
| Swimmer Type | Wetsuit Benefit |
|---|---|
| Poor body position | Significant (hips float) |
| Heavy kicker | Moderate (less need to kick) |
| Good technique | Moderate |
| Elite swimmer | Small but measurable |
Technique Adjustments
Kicking: Do Less
Without wetsuit: 2-4 beat kick for body position With wetsuit: 2-beat or almost no kick
Why:
- Wetsuit provides buoyancy (no kick needed for position)
- Kick uses energy (save for bike/run)
- Wetsuit restricts leg movement anyway
The adjustment:
- Light 2-beat kick for timing
- Focus on hip rotation, not kick
- Let legs trail naturally
Body Position: Already There
Without wetsuit: Work to keep hips high With wetsuit: Buoyancy does it for you
Why:
- Neoprene is naturally buoyant
- Especially thick around torso
- Creates "floating" sensation
The adjustment:
- Relax into horizontal position
- Don't fight the buoyancy
- Accept the different feel
Hand Entry: Higher
Without wetsuit: Normal entry, shoulder-width With wetsuit: Slightly higher entry
Why:
- Restricted shoulder flexibility
- Need to clear the water
- Avoid catching on suit
The adjustment:
- Higher hand recovery
- Enter at slight angle
- Don't rush the entry
Pull: Emphasize Catch
Without wetsuit: Full stroke cycle With wetsuit: Focus on catch and early pull
Why:
- Suit restricts some movement
- Position already good (focus on propulsion)
- Catch is where power comes from
The adjustment:
- Strong early vertical forearm
- Emphasize front half of pull
- Don't over-reach at back
Rotation: Modified
Without wetsuit: Full body rotation With wetsuit: Slightly restricted rotation
Why:
- Suit has some resistance
- Especially around torso
- Still need to rotate, just less
The adjustment:
- Rotation happens, but less extreme
- Don't force full rotation
- Match rotation to suit flexibility
Wetsuit Fit and Feel
Proper Fit Checklist
- Snug but not restrictive
- No gaps at arms or legs
- Comfortable at neck
- Can take full breath
- Can swim with full range of motion
Breaking In Your Wetsuit
Before race day:
- Wear it at home (get used to feel)
- Swim in pool if allowed (many don't allow)
- Open water practice sessions
- At least 3-4 swims before race
Chafing Prevention
Problem areas:
- Neck
- Underarms
- Behind knees
- Ankles/wrists
Solutions:
- Body Glide or Aquaphor
- Apply generously before swim
- Especially at neck (most common)
Swimming Faster in Your Wetsuit
Maximizing Buoyancy Benefits
Do:
- Relax and let suit lift you
- Focus on forward propulsion
- Reduce kick to minimum
- Enjoy the "floating" feeling
Don't:
- Fight the buoyancy
- Kick hard (wastes energy)
- Tense up
Stroke Rate Considerations
Some swimmers benefit from:
- Slightly faster stroke rate
- Shorter, quicker strokes
- Taking advantage of buoyancy to maintain speed
Others prefer:
- Normal stroke rate
- Longer glide (suit maintains position)
- Same rhythm as pool
Experiment in training to find what works for you.
Wetsuit Removal Strategy
Why It Matters
Fast wetsuit removal can save 30-60 seconds in T1.
The Technique
During final 100m:
- Reach back and pull zipper
- Loosen neck seal
Running to transition: 3. Pull suit off shoulders 4. Arms out of sleeves 5. Push suit to waist while running
At transition spot: 6. Push suit below knees 7. Step on suit to remove feet 8. Leave suit on ground (or designated area)
Practice Tips
- Practice removal after every OWS
- Time yourself
- Wet suit comes off easier than dry
- Number on arm should be visible after removal
Race Day Wetsuit Tips
Before the Race
- Apply Body Glide (neck, armpits)
- Put suit on 15-20 min before start
- Leave zipper slightly open until start
- Practice pulling zipper while suited
During Warm-Up
- Get in water to adjust
- Swim a few strokes
- Check for leaks or issues
- Final adjustment before start
If Wetsuit Is Optional
Consider wearing if:
- Water is cool (<24°C)
- You're a weaker swimmer
- Conditions are rough
- You need confidence boost
Consider not wearing if:
- Water is warm (>24°C)
- You're a strong swimmer
- Comfort in warm water matters
- Practice time in wetsuit is limited
Wetsuit Legality
Temperature Rules (ITU/USAT)
| Water Temp | Age Group | Elite |

Common Wetsuit Mistakes
Mistake 1: Wrong Size
Problem: Too loose (drag), too tight (restrictive) Solution: Get properly fitted, try multiple brands
Mistake 2: No Practice
Problem: First time in wetsuit is race day Solution: 4+ OWS sessions before race
Mistake 3: Too Much Kick
Problem: Fighting the suit, wasting energy Solution: Reduce kick, trust buoyancy
Mistake 4: No Body Glide
Problem: Chafing, especially at neck Solution: Apply generously, especially neck
Mistake 5: Slow T1 Removal
Problem: Lose time fighting suit off Solution: Practice removal after every swim
