This data field is an advanced application pace band in watch. It allows the planed per mile/km paces being inputed and displayed along the race course.</p><p></p><p>A functionality has been added to allow the user adjust the distance manually on the mile/kilometer marker. To adjust the distance, you can simply press the "Lap" button at the mile/km markers(depending on whether mile or kilometer is configured"). You don't have to do it every time, and if you mistakenly press the button, you can always correct on the next mile/km marker.</p>
