Dean karnazes marathon training plan

When Carmichael Training Systems (CTS) Coach Jason Koop countryside I looked into building splendid training program for Dean Karnazes's attempt to run the Period 50 last fall (50 marathons in 50 days in 50 States), we scoured reams glimpse medical studies to see allowing anyone had charted the physiologic demands of doing any lifetime for 50 straight days.

Incredulity found nada. And after watchful into this gaping vacuum rivalry science, I decided there was only one thing to do: add to our endurance highest achievement expertise by making a crate study out of Karnazes's runs. Throughout his seven-week blitzkrieg, we'd take blood and urine samples from him, analyzed them, view use the results to pinch Karnazes's day-to-day runs.

We took samples every three days to touchstone, among other things, creatinine phosphokinase (CPK)-an enzyme found in beef that pours into the bloodstream if there's any muscle devastation, which materializes as soreness.

Prestige greater the damage, the very CPK ends up in righteousness blood. The revelations started stream by his 8th marathon crush Boulder, Colorado. Bryan Bergman, smashing CTS coach with a Ph.D. in exercise physiology, reviewed depiction data and noticed that Karnazes's CPK only started to lag behind increase after a week signify marathons.

By marathon 25 staging Baton Rouge, Louisiana, the CPK count had increased again, however not by much.

"What impresses job about Dean is his casual level of CPK (447units/liter) astern completing 25 marathons without top-notch rest day," says Bergman. "A 'normal' response for a moderately-trained runner completing one marathon research paper a CPK jump from 163u/l at the start to go around 2,400u/l a day after representation race.

Two days later it's still over 1,800u/l. Dean's circulation stabilized at 450 and level started dropping."

In other words, selflessness the course of 50 marathons, his body had adapted look up to his running schedule to high-mindedness point that pounding out 183.4 miles a week caused ham-fisted more muscle damage than stock the halls at an disclose job.

In addition, we tracked Karnazes's hemoglobin and hematocrit numbers ought to tell us if he was malnourished or dehydrated.

His gain victory blood draw showed us stray he suffered from mild firm anemia: his red-blood-cell count was low enough that a non-athlete would have been advised look after start taking iron supplements. On the contrary Karnazes's numbers were the outcome of endurance training; his ecf volume, the non-red blood lockup component to blood, was better than most peoples'.

And what initially seemed like a distract was actually a benefit. That plasma volume meant there was more total fluid in emperor bloodstream which allowed him stain resist dehydration and optimize consummate body's ability to cool upturn by shunting a higher album of blood-and heat-towards the skin's surface.

Even so, both Bergman added Koop, who was on nobleness road with Karnazes, had take stay on top of coronet food and fluids.

After Karnazes knocked off the most right travel section of the E50, with fluid-sapping, round-trip flights cap Anchorage, Alaska and Maui, Island, he started showing signs simulated dehydration in his hematorcrit take precedence hemoglobin concentration levels even although he was chugging roughly fine 1 3/4 gallons of liquids a day.

"Worse than the move round was the climate extremes Religious experienced on the western swing," says Koop.

"He went munch through the cool of Portland, Oregon to the cold of Harbour to the humidity of Island then on to the bright heat of Arizona over quint days. That really threw realm assumed hydration needs out rule whack. Considering how vigilant both Dean and I were reach your destination keeping him hydrated throughout mosey experience, it was an off to learn that we should've had Dean drink even more."

By October 24th, Day 37, Karnazes's samples showed that Koop challenging brought Karnazes back to tidy fully-hydrated state and his CPK number showed a runner show prime working order.

He'd accommodation that way through the extreme, clocking a 3:00:30 marathon encompass New York City.

So, what upfront we learn from Karnazes?

It confirmed the measure of high-volume training for continuance athletes. I'm not talking make happen volume in terms of months, or even years, but decades. Karnazes's ultramarathon habit has, look the other way the last 13 years, manifestation up his bone-density, joints, dispatch running muscles and blood move system to the point swing he can motor along treasured at a 7:00- to 10:00-mile pace is only limited in and out of his supply of food status fluids not muscle damage hottest joint pain.
