Great topic and we’ll spend some time on it next week for sure. I would say CTL is the metric in TrainingPeaks I look at the most but it is still just one metric. We do indeed talk about a CTL of 80-120 for various big mountain objectives. Of course those are very individual and only taking into account the last 42 days of training. Honestly I mostly use the CTL to hold athletes back more than push them. If they’re making big jumps in CTL every week then overtraining is a strong possibility. I like to try and paint a big picture using CTL, TSB (form), total training time, and vertical gain/loss to keep track of where we are and how were progressing. The overarching question in my mind regardless of the metrics is the athlete recovering from the workload in an acceptable way. I would way rather send someone off on a big objective with a CTL of 90 healthy and rested than with a CTL of 101 overtrained. Its a fine line sometimes.
I know this will be covered on our next call but I thought I’d get it out there –
I’ve read on the Uphill Athlete website and elsewhere that TP’s CTL is not the ultimate metric to focus on. I’m also aware that CTL is more backwards than forwards looking so it’s not a great tool to plan training on other than to compare historical results with the training that led to those results to know what to do/not to do.
But I’ve also seen generalizations that Denali requires a 90 day CTL of 75, Everest 120, etc.
So CTL is still a big part of tracking fitness for Uphill Athlete, but I’m wondering what other TP metrics we should be looking at. Weekly duration in Zone 2 in conjunction with weekly TSS? In other words, trying to reach a target TSS number all in Zone 2 (which will lead to CTL increases)?
