Integrated Heart Rate Based Training

The new RunX includes workouts for all race distances written by Coach and U.S. Olympian Kate O'Neill Tenforde. Workouts are pre-programmed - just select and run. Choose from a variety of fun daily workouts to challenge yourself or train for a race.

For both experienced and new runners, the RunX GPS running app offers patented training tools to improve your fitness and race times. See your fitness improve and yourself get faster with our patented run heart rate benchmarking and lactate threshold tracking. Because the pursuit of excellence is for everyone.

We tell you how fast to run. We give you a target pace and guide you each time you run. As your training progresses, you perform different runs at different paces. Each pace has a different purpose: endurance, speed, or power.

See how much your fitness improves with our integrated heart rate fitness tracking tools. Test your fitness at any time by performing tailored workouts with automatically personalized goals and parameters. Note: You must wear a Bluetooth heart rate monitor (sold separately) to take advantage of our HR based features.

Get better faster. Tracking your heart rate fitness allows us to update your target paces so you always run at optimal speed – not too slow and not too fast. Get the most fitness benefit out of each run.

Race smarter with our Race Predictor. Armed with your predicted race pace, know how fast to start the race to achieve your best possible time.
