Before you start
The pre-run screen
The Run tab shows your pre-run screen. If you have an active training plan, today's scheduled workout appears as a banner at the top — tap it to start with the correct structure already loaded.
Today's workout
If a training plan is active, the scheduled workout for today appears as a card above the mode selector. Tap "Start This Workout" to begin the structured session with intervals and targets already configured.
Shoe selector
Your default shoe appears at the bottom of the pre-run screen. Tap it to choose a different pair before starting. After the run, the selected shoe is credited automatically.
Mode 1
Outdoor GPS
The default mode. Uses iPhone GPS and CoreLocation for accurate distance and route recording. Best for roads, trails, and tracks.
-
1
Select Outdoor (default)
The toggle at the top of the pre-run screen should already show Outdoor. If it shows Treadmill, tap to switch back.
-
2
Tap Start Run
A 3-second countdown appears while GPS acquires a fix. Step outside before tapping — buildings block GPS signal on the first fix.
-
3
Keep your phone accessible (or use your Watch)
Your iPhone needs to stay on your person for GPS to work — arm band, vest pocket, or hand. If you have an Apple Watch, you can put the phone away after the countdown; the Watch handles GPS from that point.
GPS accuracy settings
- •Accuracy target: best navigation quality
- •Points with accuracy worse than 20 m are filtered out
- •Speeds above 43 km/h are discarded as GPS glitches
- •Location updates stop automatically when you end a run
Mode 2
Treadmill mode
No GPS needed. Cursa measures distance using your iPhone's motion sensors — just select Treadmill, hit Start, and run. No speed entry required.
-
1
Select Treadmill on the Run Type toggle
On the Run tab, tap the toggle to switch from Outdoor to Treadmill. The toggle highlights teal to confirm treadmill mode is active.
-
2
Pick a workout template (optional)
Scroll the My Workouts row to choose a structured session — intervals, tempo, easy run, or any custom template you've built. Skip this step for an unstructured run.
-
3
Tap Start and begin running
Hit the big Start button, step onto the treadmill, and go. No belt speed to enter — Cursa starts tracking immediately.
-
4
Watch your live metrics
Heart rate, time, distance, cadence, and average pace all update in real time. Distance shows an "est." label to reflect that it's sensor-based rather than GPS-derived.

In-run alerts
Splits and personal records
Split alerts
A banner slides in from the top of the screen at every kilometre or mile (matching your unit preference in Settings). Your split pace and total elapsed time appear. The banner clears automatically after a few seconds.
Personal record detection
Cursa watches your cumulative distance in real time. The moment you pass through a standard distance (1 mile, 5K, 10K, half marathon, full marathon) faster than any previous run, a PR celebration overlay appears. It acknowledges the moment without pausing your run.
In-run coaching
Pace Coach
Cursa watches your pace throughout a run and tells you when you're drifting off target — without firing on every traffic light or hill.
How it works
When you're running a structured workout with a target pace, Cursa monitors your rolling pace continuously. If you stay off-target for a 15–30 second window — not just a momentary GPS flicker — it lets you know. The first alert is always a haptic tap only. Voice cues add context if you've enabled them for that workout type: for example "20 seconds over target for 18 seconds, flat ground."
Quiet mode
During a structured workout (interval session or plan workout), the active-run screen shows a small Coach on button beside the LAP control. Tap it once to silence pace alerts — both voice cues and haptic taps — for the rest of that run. The label flips to Coach off; tap again to re-enable. Your saved Pace Coach settings aren't changed, and the silence resets for the next run. The button doesn't appear on free runs (Pace Coach behaviour there is driven entirely by your settings).
Configurable per workout type
Pace Coach has separate on/off toggles and sensitivity settings for each workout type — easy runs, long runs, tempo, and intervals. Configure everything at Me → Pace Coach.
Share your run
Live Tracking
Let friends and family watch your run in real time. Enable sharing before you start — they get an email link and can follow your dot on a map in any browser. No app required on their end.
-
1
Enable "Share Live" before starting
On the pre-run screen, toggle Share Live on. When you tap Start, Cursa begins broadcasting your GPS automatically. The toggle is off by default each session — you opt in per run.
-
2
Beacon contacts get emailed automatically
Anyone you've added as a Beacon contact receives an email the moment your broadcast starts — with a link to the spectator page. You configure contacts once at Me → Privacy → Notify on start and they're notified on every future live run. No texting required from the start line.
-
3
Finish your run
When you stop, the live feed closes. Spectators see a run-complete state. The link is time-limited and stops working once your run ends — it doesn't stay active indefinitely.
Beacon contacts
Add email addresses as Beacon contacts in Me → Privacy → Notify on start. When you start sharing, they get an email automatically — no need to text them the link each time. You can send yourself a test email from the same screen to confirm delivery before a real run.
Privacy controls
Live Tracking can be disabled globally at Me → Privacy → Live tracking. Ghost mode hides your name from the spectator page — spectators see your position but not who you are. Ghost mode and live tracking cannot be on at the same time; the app warns you if you try.
