Some weeks ago the "Run" part of my watch showed stranges values. I run almost the same distance several days a week and for the last 3 years I have hade almost the same result as for distance -9 km - speed 8 - cal. ca. 700, but suddenly the same values where ,8 km and cal. 9. I checked for upgrade, found none, run a reset, but with the same result.
Yesterday I tried out the cycle and this works perfect.
