10-Week All-Mountain Base Plan: Build Aerobic Foundation for Trail Riding
For all-mountain riders who want a fitness foundation that holds up on real terrain — long climbs, variable surfaces, days that don't end when you expected. Ten weeks, three sessions per week, all aerobic. The extra two weeks over a standard base plan exist because all-mountain riding asks more of your body than the mileage suggests: terrain variability means your aerobic system is constantly working even on easy days. Cadence work is woven throughout because smooth pedaling matters more on trail than on road. One threshold session in week nine so the finish line doesn't feel exactly like the start. No power meter needed — RPE and heart rate are all you need.
