6-week Spring Gralloch gravel training plan (Zwift compatible)

If you’re an intermediate cyclist targeting the Gralloch gravel race and coming out of winter ready to step things up, this 6-week plan is designed to kick-start your spring training and guide you toward the specific demands of Scotland’s premier gravel event. It’s the ideal transition phase to rebuild rhythm, lift fitness, and develop the strength, resilience, and race readiness required for the fast, punchy, and relentlessly varied terrain around Gatehouse of Fleet.

Who’s it for?
This training plan is aimed at intermediate gravel cyclists with a solid base of fitness who are ready to begin a more purposeful build toward The Gralloch. Whether you’ve trained consistently through winter or are just finding your groove again as the days lengthen, this plan provides structure and direction at exactly the right time of year. Importantly, it’s written by a Gralloch finisher, shaped by real race experience and a clear understanding of what the event demands physically, mentally, and logistically.

Is it for you?
This plan assumes you’re comfortable riding both indoors (such as Zwift) and outdoors, and happy blending structured quality sessions with longer endurance rides as conditions improve. It’s ideal if you want to transition smoothly from winter training into more event-specific preparation without burning out, while rebuilding aerobic fitness, strength, and durability. The focus reflects the realities of The Gralloch: fast gravel and forestry roads, rolling terrain, frequent changes in pace, and repeated punchy efforts that reward efficiency, good pacing, and resilience.

What’s involved?
The plan builds progressively over 6 weeks, carefully balancing structure with flexibility to support consistent progression. Each week targets the key training zones, using indoor sessions for precision and efficiency alongside outdoor rides to develop endurance, strength, fatigue resistance, and real-world gravel skills. There’s a strong emphasis on aerobic conditioning, sustained tempo and sweet-spot work, cadence control, and maintaining power through repeated efforts; all crucial for handling the varied surfaces, constant rhythm changes, and cumulative fatigue that define The Gralloch.

The goal isn’t to peak during these six weeks. Instead, it’s to come out of this block fitter, stronger, and more confident, perfectly positioned to move into the final, more Gralloch-specific preparation phase ready to take on one of the UK’s toughest and most iconic gravel races with confidence.
