    Background: The current classification of the hiking trails us-ing an agreement between lab and field test is inexistent. The aim of this study was to characterize a single route in a physiological basis. Methods:Twenty-nine subjects underwent a 11km hike. The velocity and heart rate (HR) were monitored continuously. In a separate day, all subjects under-went a laboratory test to measure both HR and Oxygen uptake (VO2). Lin-ear regressions between net HR (HRnet) vs %VO2 reserve were computed. Results: The mean coefficients of determination were very high (R2=0.98). The calculated %VO2reserve mean values for this route were 42%. Conclu-sions: This route elicited light-to-moderate intensities. When hiking in this or in similar round routes, the formula %VO2reserve=0.64+0.77*HRnet can be used to assess the hiking intensity. The complementarity of the field and lab tests proved to be useful and reliable in defining the energetic de-mands of the hike.
