Cycling Training from Zero: A 12-Week Plan from Completely Inactive to Completing 100 Kilometers

A Plan for Complete Beginners

This plan is designed for those who have never seriously exercised or have just gotten a road bike and don’t know where to start. The goal is to safely and comfortably complete a 100 km ride after 12 weeks.

Gear You’ll Need

Before starting training, make sure you have these essentials:

• ✅ A suitable road bike or commuter bike
• ✅ A helmet (essential!)
• ✅ Water bottles x2
• ✅ Cycling jersey and bib shorts (with padding)
• ✅ Basic repair tools

Training Principles

1. Progress gradually: Increase training volume by no more than 20% each week
2. Listen to your body: Stop if you feel pain
3. Rest is part of training: Don’t ride every day
4. Stay in the aerobic zone: Most of the time you should be able to talk but be slightly breathless

Race-Day Strategy for the 100K

Pacing advice:

• Maintain a conversational pace throughout
• Plan a 15-minute refueling stop every 40-50K
• Riding for more than 4 hours is normal, don’t rush

Nutrition plan:

• Drink 500-700ml of water per hour
• Consume 30-40g of carbohydrates per hour
• Bring spare food (bananas, rice balls, energy bars)

Common Challenges and Solutions

Problem	Solution
Knee pain	Lower the resistance, increase cadence; see a doctor if it persists
Saddle soreness	Check your bib shorts padding, shorten each ride
Out of breath	Intensity is too high, slow down
Leg cramps	Replenish electrolytes, stretch your calves

After completing your first 100K, you’ll have a whole new understanding of your body and what you’re capable of. You’ve got this!
