Introduction: power is an important variable in performance assessment. With the increasing availability of power measurement devices, it is simple to associate watts to the running Functional Threshold Power measured in watts (rFTPw) as indicated by Vance (2016). The main goal of this study is to find the most appropriate methodology for rFTPw determination. Material and methods: five different methodologies were carried out in 9 recreational triathletes (22.9 ± 4.8 years) to calculate rFTPw: 3-minute test, 3-minute – 9-minute test, 3-minute – 9-minute Stryd test, 3-laps – 6-lap test and 30-minute test. All tests were performed on an athletics track with a Stryd footpod. Results: the 3-minute – 9-minute test presented a lower average error in comparison to the mean rFTPw value (rFTPw M) of all power and pace measurement tests. Conclusions: the 3-minute – 9-minute test could be the best choice regardless of the distance or duration of the competition because rFTPw changes depending on the duration of each test. The watts associated with Critical Speed (CS) and obtained in the 3-minute test are not a valid measure, given their greater average error in both power and pace. The 30-minute test could be an alternative to determine rFTPw through the data obtained in a training session or competition of similar length. The tests with the lowest average error in power are the ones with the lowest error in pace. Therefore, pace remains the main variable to monitor external load in running.
