Your Blood Work Looks Fine. So Why Are You Getting Slower?

Your Blood Work Looks Fine. So Why Are You Getting Slower?

Most Masters cyclists have been told the same thing at some point.

You go in feeling off. Energy’s down. Recovery is lagging. Power numbers that used to come easily are now a grind. Your doctor runs a panel, scans the results, and tells you everything looks normal.

And you believe them. Because you want to.

But here’s what we’ve learned running Longevity Audits with our athletes: “normal range” is built for sick people. The reference ranges on standard blood work are calibrated for the general population — which means the average sedentary adult who hasn’t ridden 5,000 miles in the last year.

That range is not calibrated for you.

Normal Is Not Optimal

When Christine Tanner reviews blood work, she’s not asking whether a number falls inside the reference range. She’s asking whether it’s compatible with what that athlete is asking their body to do — training, recovering, adapting, competing into their 60s and 70s.

Those are different questions. And the gap between them is where most Masters athletes are losing performance they don’t know they’re losing.

We’ve been running Longevity Audits for the past year, and the pattern we see consistently is this: athletes who are doing everything right — training smart, eating well, sleeping reasonably — still have hidden markers pulling the brakes on their performance. And none of it showed up on a standard doctor’s panel.

Here are four examples from our own program.

“My doctor said everything looked fine.”

One of our athletes — competitive racer, early 60s, 30 years of riding — came to us after two seasons of unexplained decline. Power was dropping. Recovery was slow. He was training as hard as ever. His doctor had run a basic panel. Normal range across the board.

We ran a full Longevity Audit.

His fasting insulin was 4.0 — genuinely elite metabolic health. But his testosterone had quietly collapsed. Not from age, not from a medical condition — from the plant-based protein sources he’d switched to two years earlier. Pea protein, beans, hummus. A health-conscious choice that was suppressing the hormonal signal his body needed to respond to training.

The fix was DHEA and B12 — both available over the counter — and a return to animal protein sources. No prescription. No specialist. He raced again six months later.

“I spent four months worried I was making a mistake.”

Another athlete — early 70s, analytically sharp, pharma industry background — had been put on statins by his doctor for elevated cholesterol. The medication gave him burning leg pain. He stopped taking it. Then spent four months anxious about his cardiovascular health.

When Christine reviewed his full panel, his HDL was 80. Triglycerides were 52. Those numbers represent essentially zero cardiovascular risk. His LDL particle sizes were the large, protective pattern. The statin was addressing a number his doctor was watching — not a risk his body actually had.

What we did find: Vitamin D at 33 (target 60+), free testosterone suppressed, and fasting insulin elevated from consistent grain consumption. Modern wheat carries glyphosate residue that disrupts gut function and hormonal signaling. He’d been eating whole grain toast every day for years.

The protocol: eliminate grains, add DHEA and Vitamin D — both OTC. Four months later he rode 3.5 hours, 40 miles, 4,000 feet of elevation — on one energy bar.

“I needed a six-hour nap after every hard ride.”

A third athlete — competitive climber, under 150 pounds, works a demanding job — came to us because he couldn’t function after training. Every hard session wiped him out for the rest of the day.

His food log: Cheerios. Pop-Tarts. Cookies. A diet built around sugar, not by choice but by habit.

His B12 came back at 445 — technically in range, but well below the 800–1000 level where neurological function and energy output are optimal for an athlete under load. Glucose trending pre-diabetic. Testosterone low. Epstein-Barr antibodies elevated, suggesting his immune system was still managing a viral load.

The protocol: 60g animal protein at breakfast, carbs cut from the first half of the day, B12 injections, DHEA, Vitamin D, EPA/DHA.

Week one was brutal — classic carb withdrawal. By day four, the energy came back. Recovery improved within two weeks. His words: “The addiction to sugar — I have to stop letting that rule so much.”

I Run This Program. I Still Needed It.

I’ll be direct about my own results, because I think it’s important.

I’m Matt Tanner, co-founder of Rollfast. I’ve been doing TRT for years, eating 350–400 grams of protein daily, training with precision zones. I know this stuff. And in February of this year, my numbers were a mess.

My estradiol came back at 16.4 pg/mL. Optimal is 30–50. The reason: I’d been taking anastrozole every day to prevent estrogen spikes, and it had silently depleted a hormone my body depends on for recovery and emotional regulation. I was irritable, recovering slowly, and had no idea why.

Christine also found my thyroid undertreated and my PSA at 7.2, pointing to inflammation I wasn’t aware of.

One month after adjusting the protocol: estradiol 38.5, thyroid T4 doubled, PSA down 58%, fasting insulin back to 4.1, body weight dropped 6 pounds — not from eating less, from clearing systemic inflammation.

On the day I went in for my follow-up blood draw, I had one of the best rides of the year.

What the Longevity Audit Covers

Christine reviews a comprehensive panel built specifically for Masters athletes — not a basic metabolic screen. It covers:

Hormones: Testosterone (free + total), DHEA, estradiol, thyroid
Metabolic: Fasting insulin, glucose, HbA1c (optimal insulin target: under 5)
Inflammation: CRP, PSA
Micronutrients: Vitamin D, B12, magnesium, ferritin
Recovery markers: Liver function, kidney function, red blood cell health
Every marker is reviewed against performance-optimal ranges — not just the clinical reference range that tells you whether you’re sick.

The Investment

The Longevity Audit is $499. That covers the lab work, the full blood draw, and Christine’s 45-minute consultation. There’s no separate lab bill.

For context: a comparable panel ordered through a conventional lab typically runs $350–$500 before anyone interprets it. Christine’s interpretation — built specifically for how athletes function — is what makes the numbers actionable.

She runs a limited number of audits each month.
