Pace Timer (Running & Rowing)

Set pace or finish time, then follow a large countdown with distance and interval beep context below it.

How it works

Pace Timer is a practical pacing tool for steady efforts. You set a distance and a target pace (or a finish time), then follow a clear countdown that stays readable on any device. Optional interval beeps help you check your splits without constantly looking at the screen.

This page is built for one common problem: you know the effort you want (a pace or split), but it is annoying to keep doing the math during a run or a rowing piece. Pace Timer turns your inputs into a single target countdown and shows two helpful references on the display: your finish time target and a live “should be at” distance estimate based on elapsed time.

You can use it in two ways. If you already know the pace you want to hold, enter Target pace. If you have a goal finish time, switch to Finish time and let the tool compute the pace you need for the selected distance. Both approaches produce the same end result: a countdown to your target finish with clear units (min/km, min/mi, or /500m) and optional beep reminders.

Running mode supports km or miles. Rowing mode uses meters and a standard split per 500m. Fullscreen mode is available when you want large digits and minimal distractions, such as a treadmill, a rowing machine display shelf, or a shared screen during practice.

1) Choose mode

Pick Running for min/km or min/mi, or Rowing for /500m split.

2) Set distance

Running uses km or mi. Rowing uses meters. The finish time is calculated from distance and pace (or directly from finish time).

3) Pace or finish time

Enter a target pace like 5:00 /km or 2:10 /500m, or enter a finish time like 52:00.

4) Beeps + fullscreen

Turn Sound on for interval cues, then use Fullscreen for a big, glanceable display.

Examples with real numbers

These scenarios are written to match what you will actually type and what the timer will show. Copy them directly to confirm your setup.

Scenario A: 5K steady run at 5:00 per km

You want a clean 5K at a steady pace with a split reminder every kilometer.

Inputs
Mode: Running (km). Distance: 5. Target pace: 5:00 /km.
What you will see
Finish shows 25:00. If you start and run for 12 minutes 30 seconds, the “should be at” line will read about 2.50km.
Beeps
Turn Sound on. Set Beep every 1 km to get a cue at 1K, 2K, 3K, and 4K.
If you want structured work and rest intervals instead of a steady pace countdown, HIIT Timer is the better match.
Scenario B: 2000m rowing piece at 2:10 per 500m

You want a 2K with a consistent split and a reminder every 500m.

Inputs
Mode: Rowing. Distance: 2000m. Target pace: 2:10 /500m.
What you will see
Finish shows 8:40. At 4:20 elapsed, “should be at” will be about 1000m.
Beeps
Set Beep every 1 to cue each 500m. Set it to 2 to cue every 1000m instead.
For repeating on/off intervals (not steady split), try Tabata Timer or Round Timer.
Scenario C: 10K goal time of 52:00 (pace calculated for you)

You care about the finish time more than the pace. You want the tool to compute the required pace and then guide the effort.

Inputs
Mode: Running (km). Distance: 10. Switch Input to Finish time. Enter 52:00.
What you will see
Target pace becomes about 5:12 /km (52 minutes divided by 10 km). With Sound on and Beep every 1 km, you get a cue each kilometer to check whether you are still on target.
If you want a simple countdown with no pace math, use Countdown Timer.
Scenario D: 3.1 miles in 27:00 (mile pace computed)

You are working in miles and want a simple target for a short time trial style effort.

Inputs
Mode: Running (mi). Distance: 3.1. Input: Finish time set to 27:00.
What you will see
Target pace becomes about 8:42 /mi (27 minutes divided by 3.1 miles). If you set Beep every 0.5, you will get reminders every half mile.
Want the biggest digits possible? Use Fullscreen Timer when you only need a big clock.

Details that prevent common mistakes

Pick the right unit first

Running pace is tied to km or miles. If you switch km to mi, the meaning of “5:00” changes. Set your unit first, then enter the pace you intend to train. For rowing, pace is always per 500m.

If the Finish number looks wrong, double-check distance and unit before changing the pace.

Beep every is distance-based

Beep every is not time-based. It cues by distance progress. For running, it is in km or miles. For rowing, it is in 500m multiples. If you want more frequent checks, use 0.5 (half a km or half a mile), or 0.25 for quarter units.

If you prefer zero audio, turn Sound off and rely on the display.

Technical notes (timing behavior, audio, fullscreen)
Optional troubleshooting and behavior details
▼
Countdown timing behavior

The timer runs from a target end time while active. Normal tab switches and brief pauses in rendering may make the animation look less smooth, but remaining time is still computed from the end time when the page is active again.

Audio may require interaction

Some browsers block audio until you interact with the page. If Test beep does nothing, click Start once with Sound enabled, confirm the tab is not muted, and verify device volume.

Fullscreen behavior

Fullscreen uses the browser fullscreen API. Some devices require a direct click to enter fullscreen, and Esc exits fullscreen on desktop. Fullscreen is designed for readability and minimal UI. If you want a pure big-clock page without pace features, use the dedicated fullscreen timer.

“Should be at” is guidance

The “should be at” value is calculated from elapsed time and your target pace. It is intended as an on-screen pacing reference, not a replacement for GPS, erg metrics, or event split data. If you pause, the estimate pauses with you because elapsed time pauses.

Need a different tool? For structured intervals use HIIT Timer or Tabata Timer. For a pure big clock use Fullscreen Timer. For multiple stations at once use Multiple Timers.

Keyboard shortcuts

Click the pace timer card once, then use the shortcuts below. Shortcuts won’t trigger while you’re typing in an input field.

SpaceStart / pause
RReset to the current target
FToggle fullscreen
Tip: if shortcuts do nothing, the card probably isn’t focused. Click inside the tool area once (not inside an input), then try again.

Common scenarios

A pace-based countdown for running and rowing with pace or finish-time input, interval beeps, fullscreen mode, and keyboard shortcuts.

Steady runs with a target pace you want to hold
Enter your distance and target pace (min/km or min/mi), then follow a clear countdown. Use interval beeps to stay honest on your splits, and fullscreen for a clean glanceable clock.
For
Runners doing steady efforts, tempo runs, or pacing practice.
Not for
You want structured rounds or work/rest intervals. Use HIIT Timer, Tabata Timer, or Round Timer instead.
HIIT Timer →Tabata Timer →Round Timer →Workout Timer →
Rowing pieces with a /500m split target
Set distance in meters and a target split per 500m. Interval beeps can fire every 500m (or every 1000m, 1500m, etc.) so you can check in without staring at the screen.
For
Rowers training 2k/5k pieces or steady-state rows.
Not for
You want a repeating on/off interval timer (work/rest). Use EMOM, AMRAP, or Tabata depending on the structure you need.
EMOM Timer →AMRAP Timer →Tabata Timer →Round Timer →
You know the finish time, and want the required pace
Switch to Finish time, enter a goal time for your selected distance, and the tool computes the pace/split. Then run the countdown and use “should be at” to keep the effort even.
For
Anyone pacing a time trial or trying to hit a specific finish.
Not for
You only need a basic countdown (no pace math). Use Online Timer or Countdown Timer.
Countdown Timer →Online Timer →Fullscreen Timer →
Split reminders without constant screen-checking
Keep Sound on and set Beep every 1 unit (1 km/mi or 500m). You’ll get periodic cues while the timer continues counting down to your finish.
For
People who want pacing nudges while focusing on form and effort.
Not for
You need a silent, visual-only experience as the default. Use Silent Timer.
Silent Timer →Workout Timer →Rest Timer →
Big-screen pacing for treadmills, gyms, or group sessions
Go fullscreen for large digits, then use the countdown as a shared pacing reference. This works well when the display needs to be readable at a distance.
For
Gym use, treadmills, rowing machines, and group workouts.
Not for
You want multiple timers running side-by-side for stations. Use Multiple Timers instead.
Fullscreen Timer →Multiple Timers →Workout Timer →
Simple pacing practice plus a separate stopwatch
Use Pace Timer to hold the target effort, and pair it with a stopwatch if you want manual lap/split tracking at the same time.
For
Athletes who want a steady countdown plus manual split notes.
Not for
You only want count-up timing. Use Stopwatch or Count Up Timer instead.
Stopwatch →Count Up Timer →Meeting Count Up Timer →
Tip: For steady check-ins, set Beep every to 1 unit (1 km/mi or 500m). Use F for fullscreen, Space to start/pause, and R to reset.

Frequently Asked Questions

What is the Pace Timer?
Pace Timer is a running and rowing countdown timer that helps you hold a steady target pace. Set a target pace or a finish time, choose a distance, then follow a big, easy-to-read countdown with optional interval beeps and fullscreen mode.
How do I use it for running vs rowing?
Choose Running to work in min/km or min/mi. Choose Rowing to work in split per 500m. Then set a distance and either a target pace or finish time.
Should I enter a target pace or a finish time?
Use Target pace when you already know the pace/split you want to hold (example 5:00 /km, 8:00 /mi, or 2:10 /500m).
Use Finish time when you have a goal time and want the tool to calculate the needed pace for the chosen distance.
What formats can I type for pace and finish time?
Target pace: type m:ss (example 5:00) or seconds (example 300).
Finish time: type mm:ss (example 25:00) or hh:mm:ss (example 1:02:30).
What distance should I enter?
For Running, enter distance in km or mi (depending on the unit toggle). For Rowing, enter distance in meters.
What does “Finish” mean on the display?
Finish is the total target time for the whole distance. It’s calculated from your pace and distance (or shown directly when you’re using Finish time input).
What does “At this pace, you should be at …” mean?
It’s a live pacing check. Based on the elapsed time and your target pace, it estimates the distance you should have covered so far (in km/mi for running, or meters for rowing).
How do interval beeps work?
Turn on Sound, then set Beep every.
Running: beeps every X km or mi.
Rowing: beeps every X × 500m (example 2 = every 1000m).
Why don’t I hear beeps?
Make sure Sound is enabled, your device volume is up, and the tab isn’t muted. Some browsers require a user interaction before audio can play, so press Start once and try Test beep again.
How do I start, pause, or reset?
Use Start/Pause to control the countdown. Reset returns the timer to the current target (based on your selected mode, distance, and pace/finish inputs).
How do I use fullscreen mode?
Click Fullscreen (or press F after clicking the card once). Press Esc to exit fullscreen.
Why aren’t keyboard shortcuts working?
Click the card once to focus it, then try again. Shortcuts are ignored while you’re typing in an input field.
What are the keyboard shortcuts?
Space: start/pause · R: reset · F: fullscreen
Tip: click the timer card once so it captures keyboard input.
Does the timer keep running if I switch tabs?
The timer tracks a target end time while the page is open. Power-saving modes can affect animation smoothness or background updates, but remaining time is recalculated from the end time when the page is active again.
Which related timer should I use instead?
Need structured intervals (work/rest/rounds)? HIIT Timer, Tabata Timer, or Round Timer. Want a simple workout countdown? Workout Timer. Need a pure big-screen view? Fullscreen Timer. Want multiple timers at once? Multiple Timers. Need general duration math? Time Calculator. Need steady beat cues instead of pace math? Metronome.
Does this tool send my pace or workout data anywhere?
No. The timer runs locally in your browser. This page does not send your pace, distance, or timer state anywhere.
