4-week Winter Gran Fondo Strade Bianche training plan (Zwift compatible)

If you’re an intermediate cyclist targeting the Gran Fondo Strade Bianche, this plan is designed to help you use the winter months wisely, keep fitness moving forward, and arrive in spring ready to build with confidence. It’s the ideal bridge between winter consistency and the specific demands of Tuscany’s iconic white roads.

Who’s it for?
This training plan is aimed at intermediate cyclists with a solid fitness base who want structure and direction through the winter. Whether you’ve come off a busy season, taken a short reset, or simply want a clear focus leading into next year, this plan helps you maintain momentum while laying the groundwork for Strade Bianche–specific training.

Is it for you?
This plan assumes you’re comfortable riding both indoors (e.g. Zwift) and outdoors, and happy mixing structured quality sessions with longer endurance rides. It’s ideal if you want to stay consistent without burning out, keep variety in your training, and gradually rebuild strength, aerobic fitness, and durability, all key for the rolling terrain and repeated efforts of Strade Bianche.

What’s involved?
The plan builds progressively over 4 weeks, balancing structure with flexibility. Each week you’ll work across the key training zones, combining indoor sessions for efficiency and control with outdoor rides to develop endurance, strength, and real-world riding skills. There’s an emphasis on aerobic conditioning, sustained sweetspot work, and resilience, all crucial for long stretches of gravel and constant changes in rhythm.

The goal isn’t to peak now; it’s to come out of winter fit, motivated, and well prepared to move into more Strade Bianche–specific training as spring approaches.
