You can copy another athlete’s fueling plan. You can’t copy their training demands.

A cyclist preparing for a short track event needs a different nutrition strategy than a rider tackling consecutive days of racing. The same principle applies to runners, triathletes, and every endurance athlete: your fueling should reflect the work you’re doing, including the recovery between sessions.

That’s the takeaway from the UCI Sports Nutrition Project: useful performance advice starts with the individual.

Your bloodwork deserves that same context. Standard labs assess your results against general health ranges. ABT adds an athlete-specific lens, connecting your biomarkers with your training, recovery, and goals to guide actionable recommendations.

Save this before your next training block. Build your plan around your demands, and use your own data to train smarter.

The fitness is built. Now the goal is getting all of it to the start line.

In the final weeks before a marathon, adding more training is rarely the breakthrough. The priority shifts to protecting adaptation, resolving recovery gaps, and making sure your biology can support the pace you trained to hold.

Flat legs, harder easy runs, disrupted sleep, and slower recovery can signal more than pre-race nerves. Iron and ferritin status influence oxygen delivery. Electrolytes and key nutrients support muscle function. Cortisol, testosterone, and DHEA-S add context around training stress and recovery capacity.

Standard bloodwork looks for disease. The ABT Gold Panel evaluates these biomarkers through an athlete-specific lens, then turns the results into actionable recommendations for nutrition, supplementation, training, and recovery.

Your training plan shows the work you completed. Your blood shows whether your body is ready to cash it in.

Know what is powering your race.

You can eat more and still underfuel your training.

High-mileage weeks burn more calories than your workouts. Your body also needs energy for recovery, daily movement, temperature regulation, and basic physiology. Standard calculators and wearables estimate that total demand. Your training block deserves more than an average.

Calorify (.health) and Athlete Blood Test close the gap from both sides.

Calorify uses doubly labeled water to measure your real-world energy expenditure across an entire week. Athlete Blood Test shows how your body is responding through athlete-specific biomarkers related to energy, recovery, iron status, hormones, and performance.

One measures what your body is spending.
The other reveals how your biology is handling the workload.

Together, they give athletes better data to build a fueling plan around the work they are actually doing, not the number an algorithm assumes.

Measure the demand. Understand the response. Fuel the athlete.

Ready to stop estimating?

Cooler weather can make you feel fitter than your body is ready to prove.

Lower temperatures reduce heat strain, so the same effort may suddenly feel faster. That improvement is real, but it can also tempt athletes to increase mileage or intensity before their bodies have fully absorbed the accumulated stress of summer training.

Pay attention when faster splits arrive alongside flat legs, poor sleep, unusually high effort, or slower recovery. Your watch can show what happened during the workout. It cannot show whether cortisol, testosterone, DHEA-S, magnesium, and iron status are supporting your ability to keep adapting.

The ABT Gold Panel analyzes performance biomarkers using athlete-specific ranges, then translates the results into actionable recommendations for training, recovery, nutrition, and supplementation.

Use the cooler weather. Do not let it hide your recovery debt.

Three disciplines create one combined demand on your body.

Your watch can separate the swim, bike, and run. Your body cannot. It has to absorb the total training load, recover from it, and adapt before the next session begins.

Completing every workout does not automatically mean that adaptation is happening. Heavy legs, inconsistent energy, slower recovery, or declining power may point to performance factors training data cannot measure.

The ABT Gold Panel analyzes key nutrients, electrolytes, blood health, iron status, Vitamin D, stress hormones, and recovery markers through an athlete-specific lens. Unlike standard bloodwork focused on general clinical ranges, ABT turns your results into actionable recommendations for training, recovery, nutrition, and supplementation.

Your watch measures the work you completed. Your blood can reveal how well your body is handling it.

Test deeper with the ABT Gold Panel.

September is peak training season for athletes preparing for Berlin, Chicago, New York, and other fall marathons. As mileage climbs, iron demand and iron loss can climb with it through sweat, GI losses, red blood cell breakdown, foot-strike hemolysis, and menstruation.

That matters because iron deficiency affects an estimated 15–35% of female athletes and 5–11% of male athletes. Hemoglobin may still appear normal while ferritin, your stored iron, is already falling.

The ABT Iron Panel goes beyond a standard anemia check to assess ferritin, iron, hemoglobin, hematocrit, red blood cell indices, and reticulocytes. Together, these biomarkers create a clearer picture of the oxygen-delivery system powering your endurance, recovery, and race pace.

Do not wait until race day to discover the limiter.

Test before the taper. Know what is powering your pace. Visit athletebloodtest.com to order your Iron Panel.

Your watch tells you what happened. Your blood can help explain why.

Pace dropped. HRV changed. Recovery feels harder. Your wearable captures the output, but it cannot measure every system driving it.

Athlete-specific bloodwork adds the context:

• Ferritin for iron storage and oxygen delivery
• Cortisol for training stress
• Testosterone for repair and adaptation
• hs-CRP for inflammation
• Vitamin status for muscle function, recovery, and resilience

Standard labs compare you with the general population. Athlete Blood Test looks for performance opportunities based on the demands you place on your body.

Stop guessing at the reason behind the numbers.

Find out what is limiting your performance. Train smarter.

Ironman training pushes every system. Ferritin supports oxygen transport. Cortisol reflects training stress. hs-CRP offers insight into recovery. Vitamin D supports muscle and bone function. Testosterone plays a role in repair and adaptation.

Standard bloodwork asks whether you fall within a general health range.

Athlete Blood Test asks whether your physiology is prepared for the demands of endurance training.

Measure more than pace, power, and heart rate. Find the performance opportunities hiding beneath the surface.

Ready to see your performance in your blood?

Your hemoglobin can look normal while your iron stores are already working against your training.

For runners, cyclists, triathletes, and endurance athletes, ferritin can trend down before anemia develops. That may show up as flat workouts, heavy legs, slower recovery, or difficulty holding your usual pace.

A standard medical blood test asks whether you are sick. Athlete Blood Test asks whether your biomarkers are supporting performance.

The ABT Iron Panel measures:

• Ferritin
• Serum iron
• Iron saturation
• Total iron-binding capacity
• Complete blood count

Together, these markers provide a clearer picture of iron status, red blood cell health, and oxygen delivery than hemoglobin alone.

Built for athletes routinely monitoring iron, training at altitude, following a restricted diet, supplementing with iron, or managing a history of low iron.

Available to athletes across the U.S. through participating Quest Diagnostics and Labcorp locations.

Stop guessing. See what your training demands are doing beneath the surface.

Most athletes know how hard they're training, but very few know whether they're actually adapting. That's because recovery isn't something you can accurately feel.

Some athletes wake up tired after a great week of training. Others feel fresh while their physiology is quietly struggling to keep up. The body doesn't measure recovery with motivation. It measures recovery through oxygen availability, inflammation, hormonal balance, and nutrient status. That's why elite sport has become increasingly obsessed with biomarkers. They answer the question every athlete wants to know:

Is my body rebuilding... or just surviving?

Traditional bloodwork looks for disease. Athlete Blood Test looks for a performance opportunity.

Because the goal isn't simply to recover.

It's to recover well enough to become stronger than you were yesterday.
