Hi,
In achievements: where users get medals and personal bests etc. There are still miles (1/2 miles, 1 mile, 2 miles) even if users have "Metric" selected as the default in the settings.
Now, users who selected metrics should not be forced to see miles anywhere in the app and vice versa.
World standards for running are as follows:
400 meters. 800 meters. 1500 meters. 3000 meters etc. (100m and 200m for sprint)
