Yes, they are multisport. But the name of the watch line “forerunner” speaks for itself that these watches are primarily for runners. Here is the word from the official Garmin website in the description for this watch - “We developed this watch for you – morning joggers and keen triathletes. Let the best tool be with you in the weather for your next victory.” But the question is, why is there power for skiing, but not for running? this is a paradox.
There is power for running, but not by default in this old model. You need to use the linked data field. For newer watch models running power is native on the watch.
The name Forerunner is probably very old and in the beginning it was for runners. Then they added the XT models which is for triathlon. After that the Forerunners evolved into being light multisport watches.
Ski power was added in software version 5.20. If you got a HRM Pro or Pro Plus you can get power data.
