Using data from multiple data sources and Machine Learning you might be able to predict the result of your next exercise!When you exercise, you know you can always do better. But the main question is: how?There's a lot of data available related to your exercise, like heart rate, distance, speed etc. But there's also data that's indirectly related to your performance, like the temperature, the humidity etc. But what has the most influence?By analysing all available data from multiple sources and using Machine Learning we can see why we performed the way we did. And we might even be able to predict our performance at our next exercise!
