Pre-season MTB training plan (6-weeks)
If you’re an intermediate mountain biker coming out of winter or early spring and ready to step things up, this 6-week plan is designed to kick-start structured training and prepare you for the demands of longer, more challenging off-road riding later in the season.
The aim is to rebuild rhythm, improve fitness, and develop the aerobic strength, durability, and resilience needed for long days on varied terrain.
Who Is This Plan For?
This plan is ideal for intermediate MTB riders with an existing fitness base who want more structure and purpose in their training heading into the season.
Whether you’ve trained consistently through winter or are rebuilding momentum as conditions improve, the plan is designed to help you transition smoothly into more demanding riding without burning out.
You should be comfortable riding both indoors and outdoors, blending structured sessions with longer endurance rides.
What Does The Plan Focus On?
The training reflects the realities of endurance mountain biking:
🔹 Sustained climbing
🔹 Long steady efforts
🔹 Technical and variable terrain
🔹 Riding well under fatigue
🔹 Building durability for long days in the saddle
Across the 6 weeks, the plan develops:
🔹Aerobic conditioning and endurance
🔹Climbing strength
🔹Tempo and sweet-spot fitness
🔹Fatigue resistance and pacing control
🔹Confidence handling longer rides and uneven terrain
What’s Included?
The plan combines structured indoor workouts with outdoor endurance riding to build both fitness and real-world MTB durability.
Training progresses steadily across the block, balancing quality work with recovery to support sustainable improvement and consistent training.
The Goal
This is not a peaking plan.........The goal is to come out of the 6 weeks fitter, tougher, and more confident, ready to move into more event-specific MTB training and take on bigger rides and challenges later in the season.
