Vitamin D is your missing performanc lever.
You track your power. You probably track HRV. You might even know your last cholesterol number. But ask a room full of Masters cyclists what their vitamin D level is, and most of them will go quiet.

The 4% Nobody Trains For: Free Watts Hiding in How You Pedal
There's a number buried in the 2026 Masters training research that should make every 50-something cyclist sit up. Riders who cleaned up the timing of how their leg muscles fire through the pedal stroke picked up roughly 4% in functional threshold power, at the same heart rate. Read that again. Same effort.

Masters athletes respond to high-intensity intervals as well as

The Tailwind Trap: Why Getting “Blown Home” is the Hardest Part of the Ride
There is a common myth in group cycling: Headwinds are for suffering, and tailwinds are a free ride home. When you turn your bike and feel the wind at your back, the expectation is that the group will casually float along at 30 mph while you barely touch the pedals. But if you’ve spent enough time in a fast group ride, you know the brutal
Why Your Gym Strength Never Reaches the Pedals (and How to Fix It)
You’re strong in the gym, hitting personal bests on your heavy lifts. So why do your legs lock up and your power fade when the road pitches up? The problem isn't your fitness—it's a fundamental failure in force transfer. Most cyclists are stuck training in one dimension, leaving their raw strength trapped in the weight room. This post introduces the critical 4 Power Quadrant Framework,
