As a self-proclaimed data nerd I had to answer this one. I love numbers. I think they're super motivating. They're really helpful in terms of tracking and planning your training and also when things don't go well being able to isolate what needs to change, when things go well isolating what you did that worked and being able to replicate it. So big data fan. That being said, I think no one piece of data is that valuable. So on the bike I use a power meter, I use a heart rate monitor. We put all of that data into training peaks. It tracks fitness and recovery and form and load. So a lot of different sources of information. And I think what's useful is to be able to track trends in that information. So if you collect data in the same way week over week, month over month, year over year, then you can compare and start to build the bigger picture around that data. I also use data in the gym. We use force plates and measures of velocity especially in the off season to kind of track how I'm doing in my strength training. Simpler ways to do that are just do something like a five squat max test or we use a pull up test. So there's a lot of different ways to measure progress and a lot of different types of data. The final one I would add to that is recovery scores. I use WHOOP. I know there's a lot of other options in terms of tracking recovery. But I think having a baseline for heart rate, heart rate variability, how you sleep that's another source of data that can be useful. But again, is only useful when it's part of the story and when you know OK, when I'm in shape, this is what my data should look like. When I'm in the off season, this is what to expect. When am I just tired? When am I getting sick? So again, love data but I think it's super important to have a structure around it and integrate it all so that you get a complete picture of what your training is actually doing.
