Fear of Descending: Why It Happens and How to Rewire It
Fri Feb 06 2026
Fear of descending is not a bike handling problem.
It is a nervous system problem.
In this episode of the Triathlon Mental Performance Podcast, I break down what is actually happening cognitively when speed triggers tension on descents, and why both age-groupers and pros lose time not because they lack skill, but because their threat response subtly takes control.
When you approach a descent at speed, your brain is not evaluating experience or ability. It is evaluating uncertainty. If speed plus curve equals prediction error, the threat system activates.
Grip tightens.Breathing becomes shallow.Vision narrows.Motor control becomes rigid.
This does not feel like fear.It feels like being careful.
But across a long course, that subtle protective behaviour compounds.
This episode explains why more exposure alone does not solve descending fear, how autonomic regulation changes everything, and how confidence on descents is built through nervous system control, not bravery.
What you’ll learn • Why fear of descending is a nervous system issue, not just a skill issue • What happens cognitively when speed triggers threat signalling • How attentional narrowing affects line choice and anticipation • Why motor rigidity increases under subtle stress • How over-braking compounds time loss over a full course • Why more hill reps alone can reinforce tension • How breathing and gaze influence vagal tone and threat response • Why pros and age-groupers experience the same stress cascade • How descending confidence can be trained systematically • What allows athletes to shift from surviving descents to flowing through them
Key takeaways • Descending fear is driven by prediction error, not lack of courage • Subtle tension costs more time than athletes realise • Skill does not override stress physiology • Regulating breathing and gaze reduces threat signalling • Confidence comes from nervous system stability • Exposure without regulation can reinforce fear • Flow on descents is trainable
Work with me
If descending is costing you confidence, control, or time, it is not because you are incapable.
It is because your nervous system has associated speed with uncertainty.
That is trainable.
My 4-Call Removing Fear of Descending programme is designed specifically to rewire the stress response under speed.
We work through: – threat prediction patterns – autonomic regulation under load – breathing and gaze integration – graduated exposure without reinforcing tension
The goal is simple.
You stop surviving descents.You start using them.

We will have a short, no-pressure conversation to determine whether this work is right for you.
