Injury risk increase detection insights
We have added a new insight to KULG that detects early-warning signs for potential injury risk. This feature is based on the latest scientific research that found that the likelihood of running-related overuse injuries increases significantly when the distance of a single run exceeds 10% of the longest run completed within the last 30 days.
Now, KULG provides a risk-level insight when a run is at least 10% longer than any other run in the past 28β35 days and exceeds 15 km in distance:
Low risk: 10β30% longer
Average risk: 31β100% longer
High risk: more than 100% longer
Other improvements
Optimised the mobile web in preparation for the upcoming iOS app launch.
Corrected the heart rate vs. speed graph scale, which displayed incorrectly for some predefined time frames and intervals.
