Heads up, runners: wearable sports technology maker Polar today launched a new GPS running watch with heart rate tracking.

Priced at $149, the Polar M200 will monitor your heart rate from your wrist as you train, and offer key metrics such as your pace and distance thanks to its built-in GPS. It also tracks your daily steps, calories burned, sleep time, and sleep quality. And it's waterproof so it won't break if you get caught in the rain.

Fully charged, it offers six hours of training time with GPS and optical heart rate monitoring.

It's not just a fitness tracker: The watch can connect to your smartphone and vibrate to inform you of incoming calls, messages, calendar alerts, and social media notifications. Plus, if it notices you've been a couch potato for what it deems too long, it will encourage you to get up and move.

Meanwhile, the watch is also compatible with Flow, Polar's free online web and app service where you can monitor your training sessions, connect with other runners, and get encouragement to meet your fitness goals. Flow includes a Running Program feature, which will help you train for big events like a 5K, 10K, half-marathon or marathon. Just choose an event and Running Program will create a customized training plan tailored for your current fitness level.

"When paired with Running Program, the M200 becomes a personal trainer, coaching you during runs, adapting to your performance and bringing you closer to your goals," Polar Chief Strategy Officer Marco Suvilaakso said in a statement.

The Polar M200 will be available at some point later this year in "charcoal black" and "bright red." Also available are changeable wristbands in white, "fresh blue," and "mellow yellow" for $19.90 each.
