After introducing the new audio heart rate feature of Platysens Marlin, let us now introduce the open water training program feature to you.
Before firmware 2.11.1, if you want to use Marlin to swim with training program (e.g. freestyle 500 meter rest 1 min), you can only do it in pool mode. In view of many swimming pools are closed now all over the world, we added the training program feature to the open water mode as well. You can now set or even download open water swim training program from Training Peaks to Marlin, then you can listen and follow the steps to swim in open water. Marlin will use the GPS to measure your swimming distance and know the steps you done.
