Details about the Garmin Forerunner 245

Train more effectively than ever before

How effective is your training really? Does it improve your performance? Or is it even counterproductive? Forerunner 245 provides personalized insights into your training and recovery so you can make better decisions about your training and optimize preparation for your next race. It keeps track of your VO2max and knows how heat and altitude affect your performance. The higher your VO2max, the better your expected performance. This is exactly what the power state shows you.

Training Status evaluates your recent workouts and performance indicators to determine if you're building form, at peak form, or overloaded with your training. See how your workouts are building endurance, speed and power. Feedback on aerobic and anaerobic Training Effect makes it possible. Recovery time information helps you get the most out of your efforts. To that end, a forecast is provided to indicate when you'll be ready for the next hard session. You can even view your overall training load. It compares your training volume over the last 7 days to the optimal range for your fitness level and recent workouts.

Training plans for your level

A plan makes it easier to reach your goals. Garmin helps you with personalised training plans. From after-work runs to marathons, there's something for everyone. Simply create a training plan via Garmin Connect download it, and then start it right from your wrist.

If you're looking to hit a specific goal on your next 5k run, check out Garmin Coach. With guidance from experienced coaches and free training plans that adapt to you and your goals, you're sure to reach the finish line. You can even get a race forecast as part of your training plan. And what about when you need a change of pace? Forerunner 245 gives you additional activity profiles for sports like cycling, swimming and your sessions on the cross trainer or stepper.

Refine your technique

Want more endurance? More speed? Your running performance depends not only on your fitness, but also on how economically you run. Find out with the run analysis feature on your Forerunner 245. The watch measures key running efficiency data such as stride rate, stride length, ground contact time and ground contact time balance, vertical movement and vertical ratio. These metrics are essential if you want to know your form and improve your technique. Forerunner 245 can store all of these metrics when you wear a compatible heart rate chest strap or the compact Running Dynamics Pod, which attaches to the waistband of your shorts.

As personal as you are

Check out the Garmin Connect IQ Store and give your Forerunner 245 a personal touch with downloadable apps, widgets, screen themes and more. It's easy and free! New apps are added every day. For example, keep track of your Uber driver's arrival time, challenge yourself with the Strava Relative Effort app, and even find out if and when it's going to rain with the AccuWeather MinuteCast app.

Stay up to date

With Forerunner 245, you can stay connected while you run with smart notifications. Pair it with your compatible smartphone to receive text messages and see social media updates, emails and more right on your device. New security and tracking features allow you to easily share your location with select contacts when you need help. This can be done manually if needed or automatically with built-in accident notification. So put on your shoes and run with more confidence.

Share your activity

When you sync your activities with Garmin Connect, you're not just saving your data. Garmin Connect is a popular online community. Members can connect with others and compete in challenges, pushing and motivating each other. You can even share your successes on social media. Garmin Connect is free and available on the web or on your smartphone.

Keep an eye on your energy level

Do you have enough energy for your next run? Your Garmin helps you better assess your body's energy level. It evaluates your stress levels, heart rate variability, sleep3 and activity to determine your personal Body Battery™ value. If it's high, you can be active with a clear conscience. If it's low, you should give your body a rest. In addition, Forerunner 245 is Garmin's first running watch to feature a Pulse Ox sensor. The sensor on the wrist calculates the oxygen saturation of the blood. This value can be used to determine how well your body absorbs oxygen - especially during sleep.
