- Look where you want to go, not at the obstacle you're trying to avoid — target fixation kills
- Brake before the corner, not in it; trail-braking is advanced technique, not the starting point
- Drop your outside foot and weight it through the turn; inside pedal up to avoid pedal strike
- Tuck on straights, bike upright through corners — alternate between aero and cornering posture

The System: Read, Set, Execute
Fast descending isn't about bravery. It's about a repeatable system: read the road ahead, set your speed and body position before the corner, execute the turn, repeat. Riders who go fast downhill go fast because they spend less time braking and more time carrying momentum.
Three things separate confident descenders from frightened ones: where they look, when they brake, and how they weight the bike. Everything else is detail.

Body Position and Bike Setup
On straights, get aero. Hands in the drops, elbows bent, chin near the stem. A flat back can add 3–5 km/h on a long straight for free. Through corners, the opposite: drop the outside foot to the bottom of the stroke and weight it heavily, lift the inside foot, keep your upper body relaxed and the bike leaned beneath you.
Body position by terrain
| Terrain | Hands | Hips | Pedals |
|---|---|---|---|
| Long straight | Drops, elbows bent | Forward, back flat | Level |
| Braking zone | Drops, fingers ready | Slightly back | Level |
| Corner entry | Drops | Neutral, centered | Outside foot down |
| Corner exit | Drops | Forward again | Transitioning |

Braking: Where, When, How Hard
Brake before the corner, not in it. The front brake does 70% of the work — use both, but favor the front. Squeeze progressively; never grab. Get to your corner-entry speed by the time you're done braking, then release and let the bike carve.
Trail braking — carrying light front-brake pressure into the turn — is a race technique that loads the front tire and tightens your line. It's useful in hairpins and decreasing-radius corners, but it's not the starting point. Learn to brake, fully release, then turn.
In the wet, double your braking distance and treat the front brake like a dimmer switch, not an on/off button.

Cornering: Line Choice and Apex
Standard line: wide on entry, apex late, exit wide. This opens the radius of the turn and lets you carry maximum speed. Late-apex lines also set you up for a clean exit if the corner tightens — early apexes commit you to running wide.
Look through the corner, not at the apex itself. Your eyes should be on the exit by the time you reach the apex — looking at the apex too long is how riders understeer off the inside.
Inside pedal up to avoid pedal strike in left-right combinations. If you feel a pedal touch down, you leaned too far for your crank length — back off the lean angle next time, not the speed.

Reading the Road
Read the terrain three moves ahead. Trees and poles often mark the inside of a corner and reveal the road's true radius before the asphalt does. Shadows, wet patches, and color changes signal grip changes — slow down for anything you can't read.
Tar snakes (crack-filling tar) are slick when warm. Painted lines are slick when wet. Cattle grids demand a straight bike and steady speed, never braking on the grid itself.

Common Descending Mistakes
The biggest killer is target fixation — staring at the ditch, the guardrail, the oncoming truck. The bike goes where the eyes go. Train yourself to actively look at the line you want, and your hands will follow.
Second: stiff-arming the bars. A death grip reduces front-end feedback and makes the bike twitchy. Bend the elbows, let the front wheel talk to you through the bars.
Third: braking too late and too long. Late braking feels fast but is actually slow — you scrub speed you could have carried through the corner. Smooth is fast.
