What Units of Measure Does Runna Offer?
Runna offers a variety of units, so select the one that suits you best:
Pace and distance units: kilometres or miles
Training intensity: pace targets or effort-based (RPE)
Temperature units: Celsius or Fahrenheit
How to Change Your Pace and Distance Units (km vs miles)
Plans are optimised for kilometres by default, but you can change this at any time:
Go to Profile (top-left)
Scroll to Units
Select Optimise for Kilometres or Optimise for Miles
Tap Update (top-right)
This will regenerate your plan to reflect your preferred unit of measure. Target paces and audio cues will convert automatically. For example, if you chose to optimise for miles, "2km @ 5:00/km" becomes "1.3mi @ 8:00/mi".
⚠️ Make sure your selected unit matches what's displayed on your smartwatch (e.g. Garmin or COROS) to ensure paces and audio cues are delivered correctly.
On a treadmill
Depending on the unit of measure your selected, distances on the treadmill will be shown in kilometres or miles, and speeds will be displayed in kph or mph. If you have a compatible treadmill, we can also automatically set speeds and inclines for you.
How to Switch to Effort-Based Training (RPE)
If you prefer to train by feel rather than hitting specific pace targets, switch to RPE (Rate of Perceived Effort):
Go to Profile
Scroll to Unit
Select RPE under Workout Targets
Your workouts will then guide you based on effort level (e.g. RPE 4) instead of exact paces.
Running in hot or humid weather?
Hot or humid conditions make running feel harder than usual — your pace will naturally slow down, and that's completely normal. In these conditions, effort matters more than hitting exact pace targets.
A few things that help:
Schedule runs for early morning or evening when it's cooler
Switch to RPE (see above) so your workout is guided by how hard you're working rather than pace — this is exactly the scenario RPE is designed for
How to switch to pace-based training?
If you prefer to train by hitting pace targets:
Go to Profile
Scroll to Unit
Select Running Pace under Workout Targets
Your workouts will then guide you based on your pace instead of effort level.
How to Change Temperature Units
You can change your temperature display with the following steps:
Go to Profile
Scroll to Unit
