Training with Running Power
Running power is a great complement to heart rate training – while heart rate indicates your internal load or work rate, running power measures your external work rate. Polar’s wrist-based Running Power feature makes it an easily available metric for your running sessions.
Rethink your sprints
Power responds to intensity changes almost instantly, which makes it an excellent metric for sprints and short intervals. Instead of a certain pace or heart rate zone, you can aim for a specific power zone.
Power also has a wide dynamic range, which means it can measure your effort even on very high intensities (anaerobic work).
Keep a steady effort no matter where you run
When you run on hilly terrain you ideally want to keep your effort level steady. Pace alone isn’t an ideal metric. Running Power takes into account the changes in your pace and altitude, so you can use it to maintain a steady effort level when running uphill.
