What Is a Good Swim Pace for Triathlon?
There’s no magic number. A good pace is one you can repeat, that leaves you energy for the bike and run.
Where many age-group triathletes sit, per 100m, in open water.
A good triathlon swim pace is one you can hold steadily without burning the energy you need for the bike and run.
For most age-groupers that is roughly 1:45 to 2:15 per 100m in open water. Stronger swimmers go under 1:30. Beginners may start above 2:20.
There is no single “good” number, only a pace that is repeatable, improving, and right for your race.
Want your own number first? Use the free Swim Pace Calculator to get your pace per 100, then compare it to the ranges below.

Typical pace ranges by level
Use these as guides, not targets. They are steady open-water estimates, per 100m.
One note before you judge your own number: pool pace is usually faster than open-water pace because of walls, no sighting, and calm water. Compare like with like.
Swim pace
“Good” depends on the distance
A pace you can hold for a 750m sprint swim is not the pace you hold for an Ironman 3,800m.
The longer the swim, the more a sustainable, slightly conservative pace pays off.
So “good” is not one number. It is the number that holds for your distance, on your day, without leaving you wrecked for the bike.

The better question than “is my pace good?”
Pace is the scoreboard. The more useful questions are:
- Is this pace repeatable across the full swim?
- Can I hold it without trashing my bike leg?
- Is it improving under similar conditions?
- Do I know which part of my swim is limiting it?
Pace tells you the result. It does not tell you the reason.

Why pace alone isn’t the whole story
A faster pace can come from fitness, body position, pacing, drafting, a wetsuit, or better propulsion.
Pace alone can’t tell you which one changed.
That is the gap. You see a number move, but not the input behind it.
ZWIM measures the propulsion phase, the catch, pull, and push, as Propulsive Watts. So instead of guessing, you can train one of the inputs behind the number and watch that input change.
To set your training zones from a time trial, use the Critical Swim Speed Calculator.
The pool stays sacred. It is where the whole stroke comes together. ZWIM is for the days between pool days. It is a way to keep training propulsion when you can’t get to a lane. It does not replace the pool, and a higher number is not a promise of a faster race split. It is one more input you can finally see and train.
FAQ
FAQ
What is a good swim pace for a beginner?
Comfortably finishing the swim matters more than pace. Many beginners swim 2:10 to 2:40 per 100m. Focus on holding a relaxed, repeatable effort.
Is a 2:00/100m swim pace good?
For a steady age-group triathlon swim, 2:00/100m is a solid, sustainable pace. Whether it is “good” for you depends on your goal time and how much energy you want left for the bike and run.
How do I get faster?
Improve consistency and propulsion, not just effort. Keep swim frequency high, including the days you can’t reach the pool, and train the catch-pull-push that creates the pace.
Does pool pace match open water?
Usually not. Pool pace is generally faster thanks to walls, no sighting, and calm water. When you judge your number, compare pool to pool and open water to open water.
Swim pace
Start with your number
A good pace is the one you can repeat, hold without wrecking the bike, and watch improve over time.
Get your own per-100 number, then come back to the ranges above and see where you sit. From there, the work is simple: keep showing up, and train the propulsion behind the number.
