Data, Feedback and Coaching the Person with Stephen Pelkofer
Aaron is joined by Elite 15 athlete and Threshold Lab founder Stephen Pelkofer for a conversation about what good coaching actually looks like beyond simply writing sessions. Drawing on his background in data science, basketball and elite HYROX racing, Stephen explains why he prefers to be data-informed rather than data-driven. They discuss how pace, heart rate and race splits can be useful, but only when they’re combined with context, athlete feedback and an understanding of the person behind the numbers. The conversation also covers why aerobic fitness remains the main limiter for many HYROX athletes, the danger of copying the training of people with completely different backgrounds, and why missing or shortening one session rarely matters. Aaron and Stephen explore the difference between building fitness and chasing it, how to judge progress without becoming obsessed with race times, and why the best coaching decisions sometimes involve doing less. They also discuss: Using RPE alongside pace and heart-rate data Why athletes should leave feedback after training Identifying whether an athlete needs more volume, intensity or strength Why poor pacing can make a station look like the limiter The value of repeatable benchmark sessions Why missed sessions shouldn’t automatically be added elsewhere Adjusting training around work, family, recovery and life stress Coaching the person rather than just delivering a programme Adapting feedback and communication to the individual Why consistency beats trying to force one exceptional session Find Stephen: Instagram: @stephen.pelkofer Threshold Lab: https://www.thresholdlab.co/ Join the WDM Complete HYROX & Fitness Racing System: https://wdm-coaching.fitr.training/pa/WDM_Complete Subscribe to HYROX Coaching Notes: https://www.wdmcoaching.com/newsletter
