distanceCrossCountrySkiing: HealthKit quantity type
HKQuantityTypeIdentifierDistanceCrossCountrySkiing · read from Apple’s documentation on 2026-10-02
HKQuantityTypeIdentifier.distanceCrossCountrySkiing (Objective-C HKQuantityTypeIdentifierDistanceCrossCountrySkiing) is a HealthKit quantity type in Apple's "Activity" group. Apple's abstract: “A quantity sample type that measures the distance the user has moved by cross country skiing.” Apple's discussion says its samples use length units and measure cumulative values, so in HKStatisticsQuery it takes .cumulativeSum. It is available from iOS 18.0 and watchOS 11.0.

Sum or average, and in which units
Apple states both of these in the prose of the type’s discussion, not as properties, so they are derived from Apple’s sentence and the sentence is shown with each.
Aggregation style
cumulative — in an HKStatisticsQuery, use .cumulativeSum. Apple’s sentence:
These samples use length units (described in ) and measure cumulative values (described in ).
Unit family
length — every type in this family is on the HKUnit reference.
Apple states it in the same sentence as the aggregation style, quoted above.
Empty parentheses and a dangling “described in” mark links in Apple’s sentence to other documentation pages: the generator keeps the sentence’s text, not its links, and the quote is left as stored rather than repaired.
Can apps write distanceCrossCountrySkiing?
Apple’s documentation for distanceCrossCountrySkiing does not state that its samples are read-only. Apple states read-only status only in prose, and its silence is not a statement either way, so this page makes no claim that apps can save it.
On Android Health Connect
No verified Health Connect counterpart. The cross-platform matrix pairs only metrics checked against both Apple’s and Google’s documentation, and distanceCrossCountrySkiing is not among them. A similarly named Health Connect record may exist, but a name match is not a verified mapping.
Questions
- Should I sum or average distanceCrossCountrySkiing in HealthKit?
- Sum it. Apple's documentation for distanceCrossCountrySkiing describes it as measuring cumulative values, so an HKStatisticsQuery over it takes .cumulativeSum. Apple's sentence, as read on 2026-10-02: "These samples use length units (described in ) and measure cumulative values (described in )."
- Which unit family does Apple give distanceCrossCountrySkiing?
