Vertical Kilometer (VK) Training Plan
An 8-week plan built specifically for vertical kilometer and steep uphill races — climbing-focused indoor cycling strength paired with trail running.
A vertical kilometer race is unlike anything else in trail running — pure sustained climbing with no descent to recover on. This 8-week plan builds the exact muscular endurance and torque you need through low-cadence, high-resistance indoor cycling intervals, paired with your own uphill running or hiking sessions.
This plan is dynamic
Every cycling session in this plan automatically scales its power targets to your FTP, so it adapts as you get fitter — no need to guess your numbers or redo the math yourself. Life happens too: drag any session to a different day on your calendar whenever your routine changes.
Week-by-week breakdown
Aerobic Base
Weeks 1–2Easy Zone 2 cycling to build a general aerobic foundation before the strength work begins.
Climbing Strength
Weeks 3–5Low-cadence, high-torque cycling intervals that build the muscular power sustained climbing demands.
Power Endurance
Weeks 6–7Longer torque intervals that extend your climbing strength toward race duration.
Peak & Taper
Week 8A final sharpening session followed by an easy recovery spin before race day.
Frequently asked questions
What makes VK training different from regular trail running training?
A VK is almost entirely sustained climbing with no flat or downhill recovery — training needs to build raw muscular endurance for climbing specifically, not general trail fitness.
Can cycling really help with a running-specific race?
Yes — low-cadence, high-resistance cycling intervals recruit the same muscle fibers and energy systems as sustained uphill running, with far less impact stress on your joints.
