Masters Gravel Racer VO2 Builder Block
Have a short window to train with real focus and want to make it count?
The Masters Gravel Racer VO₂ Builder Block is a structured 9-day training plan designed to raise aerobic ceiling, improve repeatability at high intensity, and sharpen fitness ahead of key gravel events. This is not a recovery week or a generic fitness block; it’s a deliberate, high-quality overload designed for experienced riders who want meaningful gains in a short space of time.
Importantly, this block is based on the same core principles used by an UNBOUND Gravel winner in the build-up to their A races, adapted here for masters cyclists balancing training around real life, work, and recovery demands.
Who this plan is for
This plan is designed for experienced gravel and endurance cyclists, particularly masters athletes, already training consistently and comfortable handling structured interval work and accumulated fatigue.
It’s ideal for riders training approximately 8–12+ hours per week who want to:
🔹 Improve VO₂ max and aerobic power
🔹 Handle repeated climbs and surges more effectively
🔹 Build race-ready fitness before a key event
🔹 Use a focused training window intelligently
This is not a beginner plan, and it’s not designed for athletes returning from a break.
What to expect
Across nine days, the block combines carefully structured VO₂ max sessions with aerobic support work and controlled recovery to create a powerful training stimulus without unnecessary junk fatigue.
Key areas targeted:
🔹 Increased aerobic ceiling and oxygen uptake
🔹 Improved repeatability of hard efforts
🔹 Better climbing and surge tolerance
🔹 Greater durability under accumulated fatigue
🔹 Sharper race-specific fitness for gravel racing
The sessions are demanding, but controlled. The goal is not to empty yourself every day, but to execute quality work consistently and absorb it properly afterwards.
How to use it
This block works best when placed inside a bigger training picture and followed by a deliberate recovery phase. You are not supposed to feel amazing at the end of Day 9, the real adaptation happens once the recovery starts.
Best used:
🔹 Before a key gravel race build
🔹 As a mid-season aerobic stimulus
🔹 During a focused training period or mini camp
The payoff
Executed properly, the Masters Gravel Racer VO₂ Builder Block delivers a significant aerobic boost in a short period of time using proven training principles adapted for real-world masters athletes.
Train with intent.
Recover with purpose.
