What is Pace Lane?

Pace Lane turns the workout on the whiteboard into a tap-to-time deck companion. Compose a set from reps, distance, stroke and interval — 8×100 free @ 1:30 — with warmup, main and cooldown groups, drill, kick and pull tags, and notes. Reorder, duplicate, or edit a rep mid-workout in two taps.

The pace clock is the other half: a big, glanceable clock that counts each send-off, auto-advances through reps, and shows the time remaining in your rest. It runs entirely on the phone at the wall — no network and no watch required.

Pool length is a first-class setting. Lock in 25 yards, 25 meters, 20 yards, 33⅓ or 50 meters once, and the builder computes total distance and per-rep math honestly. Your sets live in a local library and share as PDF or plain text, with no account to create.

Features

Set builder

Reps × distance × stroke × interval, grouped into warmup, main and cooldown, with drill, kick and pull tags and per-rep notes. Total yardage updates live as you build.

Pace and interval clock

A large clock face counts every send-off, auto-advances reps, and counts down the rest remaining — readable from the wall at a glance.

Coach paste

Type the set your coach wrote — 4×50 kick, 8×100 pull — and the parser lays it out as structured reps, ready to time.

Honest pool-length math

Lock 25y, 25m, 20y, 33⅓ or 50m and every distance and total is computed for the pool you actually swim in.

Edit mid-set

Change a rep, an interval, or the rest of the workout while the clock is running — two taps, no starting over.

Apple Watch hand-off

Optionally export a built set as a custom workout to the Apple Watch Workout app, so swim metrics come from Apple's own pool-swim tracking.

How it works

Build or paste the set

Compose reps in the builder or paste the coach's set as text; group it into warmup, main and cooldown, and check the live total.

Lock your pool length

Pick 25 yards, 25 meters, 20 yards, 33⅓ or 50 meters once — every rep and total is computed for that pool.

Swim to the clock

Start the set and swim each send-off; the clock auto-advances reps and shows the rest remaining every time you hit the wall.

Save and share

Sets stay in your local library and export as PDF or plain text for lane mates and the team chat.

Frequently Asked Questions

What is a pace clock in swimming?

A pace clock is the big sweep-hand clock on the pool deck that swimmers use to time send-offs and rest between reps — leaving 'on the top' or 'on the sixty' means starting when the hand hits 60. Pace Lane puts that clock on your iPhone: it counts each send-off for the set you built, advances to the next rep automatically, and shows exactly how much rest is left. It runs fully on the device, so it works at any pool.

What does a swim set like 8x100 @ 1:30 mean?

It means eight repeats of 100 yards or meters, leaving every 1 minute 30 seconds — the interval includes both the swim and the rest. If you finish a 100 in 1:20, you get 10 seconds at the wall before the next send-off. Pace Lane uses exactly this notation in its builder and parser, and the clock manages the send-offs so you only have to swim.

Is there an app to build swim workouts?

Yes — Pace Lane is a swim set builder for iPhone. You compose a workout from reps, distance, stroke and interval, organize it into warmup, main and cooldown groups, and tag reps as drill, kick or pull. The total yardage updates live, and the finished set is ready to run against the built-in pace clock.

Can I use my iPhone as a pace clock at the pool?

Pace Lane is designed for exactly that: a big, glanceable clock face made to be read from the wall, counting send-offs and rest for the set you loaded. Timing is pure on-device — no network connection and no watch required. Set the phone on the deck at the end of your lane and swim to it.

How do I time rest intervals between swim reps?

The standard way is a send-off interval: each rep starts on a fixed clock time, and your rest is whatever remains after you finish the swim. Pace Lane counts down the time remaining in rest and rolls into the next rep automatically, so you never have to do wall math mid-set. It works the same whether the set is 4×50 kick or a long broken swim.

How do you calculate the total yardage of a swim workout?

Multiply each line's reps by its distance and add the lines: 8×100 plus 4×50 is 1,000. It gets error-prone once warmup, drills and cooldown pile up, and it silently breaks if your pool isn't the length the workout assumed. Pace Lane keeps a live total as you build and computes it for your actual pool length.

What if my pool is 20 yards instead of 25?

Distances in a written set assume a pool length, and swimming them in a 20-yard pool changes the real yardage per rep. Pace Lane treats pool length as a locked setting — 25y, 25m, 20y, 33⅓ or 50m — and computes per-rep distance and totals for the pool you actually swim in. That keeps your logged yardage honest, not approximated.

Can I type in the set my swim coach wrote?

Yes. Pace Lane's coach-paste parser takes plain text like '4×50 kick, 8×100 pull @ 1:40' and lays it out as structured reps with strokes, tags and intervals. That means the workout your coach planned on the whiteboard becomes a timed set in seconds, without tapping through menus rep by rep.

Can I edit a swim set in the middle of a workout?

In Pace Lane, yes — reorder, duplicate, or change any rep in two taps while the clock is running. Real sets drift: the lane is crowded, your shoulders are tired, the coach adds a round. The builder and the clock share one live set, so a mid-workout change doesn't mean abandoning the timer.

Can I send a swim workout to my Apple Watch?

Pace Lane can export a built set as a custom workout to the Apple Watch Workout app. Your stroke, distance and heart-rate metrics then come from Apple's own first-party pool-swim tracking, which is reliable in the water. The hand-off is optional — the pace clock itself runs entirely on the phone.

What do drill, kick, and pull mean in a swim set?

They are rep types: drill means technique-focused swimming, kick means legs only (usually with a board), and pull means arms only (usually with a buoy). Coaches mix them into sets to target specific parts of the stroke. Pace Lane has these tags built into the set model, so a line like 4×50 kick reads on the clock exactly the way it was written.

Does a swim workout app work without an internet connection?

Pace Lane does. Sets are stored locally on the device, the parser and builder work offline, and the pace clock's timing engine never touches the network. Pools are exactly where connectivity dies, so the app is built to assume there is none.

How do I share a swim set with my lane mates?

Pace Lane exports any set as a PDF or plain text, ready for the team group chat or a printout on the deck. The shared copy keeps the standard notation — groups, reps, strokes, intervals — so anyone can read it, whether or not they use the app.
