You do the running. Forerunner 245 does the thinking. This GPS smartwatch doesn\\\"t just tell you where you\\\'ve gone. It tracks your stats, crunches the numbers and gets to know all about your performance, your form, your training history and even your goals. All you need to focus on is putting one foot in front of the other. What amount of training is right for you? Forerunner 245 offers personalised training and recovery insight for smarter training decisions, helping you prepare for your next race. It keeps tabs on your VO2 max and understands how heat and altitude impact your performance. The higher your VO2 max, the higher you can expect to perform, which is exactly what is shown by the performance condition metric. Training status evaluates your recent exercise history and performance indicators to let you know if you\\\"re training productively, peaking or overreaching. See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback. Recovery time helps you maximise the benefit of your efforts by predicting when you will be ready for your next tough challenge. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
