100km Cycling Plan

Metric Century

← Back to Cycling

The metric century — 100 kilometres — is a rewarding milestone for any cyclist. It's long enough to demand proper preparation, but achievable for anyone willing to put in consistent training. Whether you're building up to your first 100km ride or sharpening your fitness for a faster finish, we've put together three free training plans to help you get there. Pick the one that matches your current fitness and timeline.

Plan A: 8-Week Beginner

  • Goal: Complete a 100km ride
  • Fitness level: Beginner — can ride 30-40km comfortably
  • Timeline: 8 weeks, 3 sessions per week + rest days

This plan progressively builds your distance from weekend rides of 35km up to a full 100km metric century. Every week follows the same rhythm: ride Tuesday, Thursday, and Saturday, with rest on the remaining days. Keep easy rides truly easy — you should be able to hold a conversation throughout. Fuelling and hydration practice on longer rides is just as important as the pedalling itself.
