Transition

Triathlon Transition

Triathlon transitions (T1 and T2) are the changeovers between swim-bike and bike-run. Learn transition strategies, setup tips, and how to save time on race day.

Quick Answer

Transitions in triathlon are the changeovers between disciplines: T1 (swim-to-bike) and T2 (bike-to-run). Often called the "fourth discipline," transitions can make or break a race and require practice to execute efficiently.

What Are Triathlon Transitions?

Transitions are timed portions of a triathlon race where athletes change equipment and switch sports:

TransitionWhat Happens
T1 (Swim-to-Bike)Exit water, remove wetsuit, put on bike gear, mount bike
T2 (Bike-to-Run)Dismount bike, change to run gear, start running

Race time includes transitions, so faster transitions mean faster finish times.

The Transition Area

The transition area is where you set up your gear before the race:

ElementPurpose
Bike rackWhere your bike hangs during swim and run
Transition spotYour gear space near your bike
Swim inEntry point from water
Bike out/inMount/dismount lines
Run outExit to run course

T1: Swim-to-Bike Transition

T1 Sequence

  1. Exit water – Run if shallow, swim to shore
  2. Remove goggles/cap – While running to transition
  3. Strip wetsuit – If applicable
  4. Reach transition spot – Find your bike
  5. Dry feet – Optional but helps
  6. Put on bike gear – Helmet first (required before touching bike)
  7. Bike shoes – On feet or clipped to pedals
  8. Grab bike – Run to mount line
  9. Mount – After the mount line

T1 Time Targets

LevelTarget Time
Beginner3-5 minutes
Intermediate2-3 minutes
Advanced1-2 minutes
Elite< 1 minute

T1 Tips

TipWhy It Helps
Practice wetsuit removalSave 30+ seconds
Pre-set helmet openOne motion to buckle
Bike shoes on pedalsFaster than putting on shoes first
Use landmarksFind your spot quickly

T2: Bike-to-Run Transition

T2 Sequence

  1. Approach dismount line – Slow safely
  2. Dismount – Before the line (flying dismount if skilled)
  3. Run to rack – Hold bike by seat/bars
  4. Rack bike – Hook by brakes or seat
  5. Remove helmet – Only after bike is racked
  6. Put on run gear – Shoes, hat, race belt
  7. Exit transition – Start running

T2 Time Targets

LevelTarget Time
Beginner2-3 minutes
Intermediate1-2 minutes
Advanced45-60 seconds
Elite20-30 seconds

T2 Tips

TipWhy It Helps
Elastic lacesNo tying required
Race beltFaster than pinning number
Feet out of shoesFlying dismount ready
Minimal gear changesLess is faster

Transition Setup

Before the Race

ItemSetup Tip
BikeCheck brakes, tires, gears
HelmetOpen, straps out, on handlebars
Bike shoesAttached to pedals or beside bike
GlassesInside helmet or on handlebars
Run shoesOpen, elastic laces, accessible
Race beltNumber attached, laid flat
NutritionGels on bike/in pockets
TowelOptional, to stand on

Transition Area Strategy

  • Arrive early to get good spot
  • Walk the transition area multiple times
  • Note landmarks and entry/exit paths
  • Count racks to your bike
  • Visualize both transitions

Time Savings

Where Time is Won/Lost

ActionPotential Savings
Quick wetsuit strip20-60 seconds
Elastic laces15-30 seconds
Flying mount/dismount10-20 seconds
Bike shoes on pedals10-20 seconds
Race belt vs. pinning30-60 seconds
Efficient layout20-30 seconds

Total potential savings: 2+ minutes compared to slow transitions.

Flying Mount/Dismount

Advanced techniques for experienced triathletes:

Flying Mount:

  1. Run with bike to mount line
  2. Jump onto saddle while bike is moving
  3. Feet go into shoes while pedaling

Flying Dismount:

  1. Unclip and remove feet from shoes while riding
  2. Coast with feet on top of shoes
  3. Swing leg over, land running

Practice these extensively before attempting in a race.

Race Week

  • Walk transition area at race site
  • Practice the exact sequence you'll use
  • Note mount/dismount line locations

Common Transition Mistakes

1. Panicking

Stay calm. Rushed mistakes cost more time than methodical efficiency.

2. Too Much Gear

Every item adds time. Question if you really need it.

3. Not Practicing

Transitions improve dramatically with practice. Include them in training.

4. Wrong Order

Helmet must go on before touching bike (T1) and come off only after racking (T2). Violations cause penalties.

Common Questions

Can I leave transition area during the race?

No—once the race starts, typically only athletes and officials are allowed in transition.

What if I can't find my bike?

Count racks, use landmarks, and note your position from multiple angles during setup.

Is drafting allowed in transition?

Transition areas typically have no drafting rules since you're running with your bike, not riding.

What's a "penalty tent"?

Some races have a penalty area near transition for rule violations. Time penalties are served there.
