Those colored zones are also indicated by similarly colored straight lines across the chart. I’ve put circles around five, numerical “TSB zones.” Each of these represents a zone indicating a stage in the training process. Now notice the circles also on the right side legend. The more negative (dropping below 0), the more tired Dave is. The more positive (the higher above 0), the fresher Dave is. Above that is positive TSB/form ('fresh') and below it is negative TSB/form ('not fresh'). Notice that there’s a “0” (zero) in that legend about in the middle. On the right side of the chart is the yellow TSB legend. But I’d like to show you another way to think about TSB-and help you manage your training. As the line rises, Dave is becoming more fresh-“coming into form.” When TSB is above the dashed yellow line in the middle of the chart Dave is “on form.” But if that line gets too high, as it was at the end of his race season around 9/1 to 10/1 on the right end of the chart, then he is very fresh, but has lost so much fitness (CTL dropped precipitously) that he is certainly not ready to race.Īll of this is how TSB is typically used to monitor training. As the yellow TSB line falls on the chart Dave is becoming less fresh-he’s losing form.

That’s a proxy for “form,” or in another word, “freshness.” Basically, it has to do with race readiness. What I want to focus on with his chart is TSB. The jagged lines are CTL (blue), ATL (fuchsia), and TSB (yellow). The accompanying chart (click to enlarge) for Dave Schell, a TrainingPeaks employee, shows his training for an entire year. A topic I’ve never written about before is how you can use TSB on the PMC to manage your training throughout the season to achieve what you are aiming for at any given time. If you are unfamiliar with these three TrainingPeaks terms you can find brief definitions here. I’ve posted a few times here on how you can use the Performance Management Chart to manage your training with topics on CTL (“fitness”), ATL (“fatigue”), and TSB (“form”).
