Overview

A century is an endurance test more than an intensity test. The one thing that matters most is a progressively longer weekend ride that teaches your body, and your fuelling, to keep going for five to eight hours.

Around that long ride you add moderate tempo and sweet spot work to raise your steady pace. A 12-week build that grows the long ride from three hours toward five or six, with recovery weeks, is a common way to prepare.

Key workouts

Progressive long ride

Tempo blocks
2x20 min at 76-90% FTP, to work on the pace you hold for long periods.
Open the workout: Tempo 2×20 →
Back-to-back weekend
A long Saturday plus a solid Sunday endurance ride, to build fatigue resistance.

Tips to get it right

  • Practise fuelling on your long rides. Riders commonly aim for 60 to 90 g of carbs per hour and drink steadily to avoid running out of energy late in the ride.
  • Train at the pace and in the position you plan to ride the century.
  • Grow the long ride gradually. Extending the weekend ride too quickly makes it harder to recover between sessions.

Frequently asked questions

How long does it take to train for a century ride?

If you can already ride 2 to 3 hours, about 12 weeks is comfortable. Complete beginners may want 16 weeks to build the long ride safely.

What is the most important workout?

The weekly long ride. Extending it steadily, with recovery weeks, is what prepares your body and fuelling for 100 miles.

Do I need a power meter?

No, but training to power or heart-rate zones makes pacing easier to judge. TrainCraft workouts set targets as a percentage of FTP, so they convert to watts from the FTP in your profile.
