*4. Duathlon Path*

> **4b1.** Biking

The bike section in duathlon uses the same core cycling habits as triathlon: be visible, stay predictable, and make sure your equipment is safe before every ride.

## Requirement 4b1a

> **4b1a.** Explain to your counselor how to ride predictably, be conspicuous, think ahead, and ride ready.

Good riding is about being easy to understand. Hold your line, signal your choices, and scan ahead for hazards before they become emergencies.

## Requirement 4b1b

> **4b1b.** Discuss what should be checked regularly to make sure the bicycle is safe to ride.

Before each ride, check tires, brakes, chain, pedals, and helmet. A bike that is “almost fine” can become unsafe quickly once speed and fatigue enter the picture.

**Quick bike check** — A simple routine before every session

- [ ] **Air:** tires inflated and free from obvious damage
- [ ] **Brakes:** both brakes engage firmly
- [ ] **Chain:** drivetrain moves cleanly
- [ ] **Controls:** handlebars and saddle secure
- [ ] **Helmet:** fits and buckles correctly

## Requirement 4b1c

> **4b1c.** Explain the importance of wearing a properly sized and fitted helmet while cycling and of wearing the right clothing for the weather.

Helmets reduce risk only when they fit right. Weather-appropriate clothing also matters because a rider who is overheating, shivering, or poorly visible is more likely to make mistakes.

> **Safety First!**
>
> In duathlon, you may start the bike leg already breathing hard from the first run. That is exactly when good judgment matters most. Stay smooth before you try to be fast.

Next, you will move to the run skills that bookend the bike section and make duathlon unique.
