All athletes should log as much information as possible in every exercise session they complete. But what should be recorded and how do you do it?
First, both objective and subjective data should be registered. In another article I have listed many tips to make sure you always get consistent objective data. However training is not only about power, heart rate, etc. Other aspects should also be monitored and logged after every workout. Let’s discuss some options.
Nutrition and hydration
Track all the gels, sandwiches, bars, etc you eat. Also how often you eat during your workouts.
Note how much liquids you ingest during the ride (eg. 500 ml in 2 hours). This will be used to track hydration status in your future workouts.
Check your body weight (naked) before and after your exercise session. Ideally, it should not drop more than 2% of your initial body weight.
Your coach or dietitian may use all this information to optimize your feeding/drinking strategy.
Psychology and Physical
Explain how easy or hard was to complete intervals and your exercise session. Compare it to the 10-point Borg’s scale (eg. hard training or easy intervals, 5 points in Borg's scale).
Try to correlate your subjetive analysis with objective data (eg. power was lower compared to my perceived exertion).
There might be signs of FTP / FTPa over- or sub-estimation there or bad sensor data.
Log how hot or cold and humid or dry was your workout. Correlate that with your hydration status (body weight before and after your exercise session).
Most training systems allow users to track their equipment. This tool can be very useful to schedule maintenances, change parts and avoid equipment surprises.
Was it an indoor (trainer, treadmill) or outdoor session?
Finally, there’s no one size fits all recipe and at the end the goal is to be consistent with your model and always try to evolve it.
