The invention relates to a system and method for analysing an activity session. A method of analyzing an activity session comprises receiving activity data for an activity, the activity data corresponding to multiple parameters; retrieving a set of threshold criteria for a particular user in view of the activity, the set of threshold criteria corresponding to the multiple parameters and at least one of the threshold criteria being based on a cardiovascular threshold of the particular user; and comparing the activity data with the set of threshold criteria to identify an effort of the user. The effort is defined by a difference between the activity data and the threshold criteria based on the cardiovascular threshold of the particular user. Classifying multiple durations of the activity into one or more predefined training type segments is based on a resistance experienced by the particular user and the identified effort of the particular user. The resistance is based on terrain. The method is executed by one or more processors.
