4-week Winter Mallorca 312 sportive training plan (Zwift compatible)

If you’re an intermediate cyclist looking to make the most of the winter months and keep your fitness moving in the right direction, this plan is designed for you. It’s the perfect way to maintain momentum through winter, build confidence, and set yourself up to progress smoothly into spring; with the Mallorca 312 firmly in mind.

Who’s it for?
This training plan is aimed at intermediate cyclists who already have a reasonable fitness base and want some structure and purpose through the winter. Whether you’ve come off a busy autumn, taken a short reset, or simply want a clear focus leading into next season, this plan helps bridge the gap between winter riding and spring-specific training.

Importantly, this plan is written by a multiple Mallorca 312 finisher, so it's shaped by real event experience and an understanding of what the course demands; physically, mentally, and logistically.

Is it for you?
This plan assumes you’re comfortable riding both indoors (e.g. Zwift) and outdoors, and are happy mixing structured sessions with longer endurance rides. It’s ideal if you want to stay consistent without burning out, keep some variety in your training, and gradually rebuild strength, aerobic fitness, and confidence ready to step things up as spring approaches.

What’s involved?
The plan builds progressively over 4 weeks, balancing structure with flexibility. You’ll work across the key training zones each week, combining indoor sessions for quality and efficiency with outdoor rides to develop endurance, strength, and real-world riding skills. The focus is on maintaining fitness through winter, building a solid aerobic base, and putting you in a great position to transition into more specific Mallorca 312 preparation in the months that follow.

The goal isn’t to peak now, it’s to arrive in spring fit, motivated, and ready to train with purpose.
