CJ Albertson (Brooks) 2:10 treadmill marathon

That is a humongous asterisk.

This guy also did a 50k at a track 2 weeks ago. Lots of long distance at fast times in extremely repetitive & monotonous environments. He either has insane focus or a mental issue

I doubt the treadmill was both accurately calibrated and level.

To run 4:58 pace at 1.5% incline is equivalent to 4:40 pace level or 18 seconds/mile faster. I have NEVER seen any data that remotely concludes the benefit of zero wind resistance is worth 18 seconds per mile. If we are generous and give 6 seconds per mile (over 2.5 minutes for a marathon) that would give him a 4:46 pace or a 2:04:50 marathon!! (plus an extra mile for show)

Runworks has 4:57.0 pace on 1.5% incline as equivalent to 4:57.4 pace on flat ground, just FYI (and 4:45.1 at 0%, not 4:40). If this conversion is accurate, I believe that he can run this on a properly calibrated treadmill. I think his 2:11 at Trials shows that he's capable of 2:08ish on a ridiculously fast course (Chicago, London, Berlin, Dubai), and he's still improving.

What does this mean? What would the asterisk denote?

That he ran it on an uncertified treadmill??

Ran what?

A workout?

What is a certified treadmill?

You have to be joking to even remotely think that piece of junk calculator is going to give you usable data. Here is a snapshot of what they calculate running into or with the wind. Are you going to believe that you can run 27.6 seconds/mile faster with a 20 mile wind at your back? Then when you turn around and run back against a 20 mph wind, you will slow down 1:40 per mile? That's ridiculous. I am guessing their treadmill calculator is just as much junk.

Do yourself a favor and start using the calculator I listed. I have used that for years and found it to be EXTREMELY accurate in real races like the Ekiden, Pikes Peak, and the world xc championships a couple years ago where I predicted the winning time within a couple seconds.

Equivalent Paces by Wind Speed

Wind Speed (negative values denote tailwinds) VO2 Demand min/km min/mile

-20 mph (-8.9408 m/s) -9.6% 3:03.0 4:54.5

-15 mph (-6.7056 m/s) -8.7% 3:04.6 4:57.1

-10 mph (-4.4704 m/s) -6.8% 3:08.0 5:02.5

-5 mph (-2.2352 m/s) -3.9% 3:13.2 5:10.9

0 mph (0 m/s) 0.0% 3:20.1 5:22.1

5 mph (2.2352 m/s) +4.9% 3:28.8 5:36.1

10 mph (4.4704 m/s) +10.8% 3:39.3 5:52.9

15 mph (6.7056 m/s) +17.7% 3:51.4 6:12.4

20 mph (8.9408 m/s) +25.6% 4:05.2 6:34.7

Have there been other guys like Albertson, who were really good in high school, okay in college in a Power 5 program, given up competitive running, and then been elite as a marathoner (his 2:11:49 in Atlanta shows sub 2:10 ability on a flat course.

His PRs are only 13:56 and 29:37.

Reminds me of another elite marathoner in the game right now: Josh Izewski. Ran for Florida, went into tri after college, now all-in on the marathon scene and running well.

You're an unregistered user, I have no idea who you are, and your calculator is trash. Runworks operates from several sources, one of which is Daniels (they're no longer allowed to use his name, but they used to list that something like half of their conversions were directly from Daniels). I run treadmill workouts all the time, and going to 1.5% from 0% is certainly not nearly as hard as your calculator indicates. It gets even more laughable at higher percentages. I've literally watched someone run mile repeats on a calibrated, $10,000 with the last one at 5.5% grade at 12 mph. Your calculator puts that at exactly a 4:00 equivalent pace at 0% grade. The guy doing the workout was looking for low/mid-4:30s effort on flat ground. Runworks puts it at 4:33. Your calculator puts it at faster than his mile PR, even if we convert for treadmill vs flat ground. Your calculator is trash.

There is no way this guy ran 2:10:00 on a treadmill plus 1 mile!! He broke the treadmill world record by 7 mins. This person could not run 2:10:00 in any conditions. Absurd post.

^This. Calculator BS aside such an effort seems pretty unreasonable, but heck no one really knows. If he did it in training, then he should be going sub 2:10 outdoors no excuses, so we'll just have to wait and see I guess.

Albertson is notorious for these massive ridiculous workouts. This was a near all out effort I'd think and 2:11 at the trials of course he could run under 2:10 if everything broke right.

Or maybe...just maybe...

A guy who PR’ed by 3 minutes on an insanely tough course in Atlanta (From 2:14–>2:11), has in fact, gotten even better in the past year and is in 2:07/8 shape on a fast course, ready to win the Marathon Project. Maybe this treadmill effort is actually closer to truth than fiction.

We’ll find out soon enough.

I think it's safe to say he was already in 2:08 shape at trials, and maybe he's even better now! I'm hoping MP winds up being a fast race that shows what he can do vs a 2:10+ race where it cimes down a fast last few miles or a sprint finish. Cam Levins is looking to be in good shape as well. Then there're some other guys who could run pretty fast times like Fauble, Mesfun, and the 2 international guys with 2:08 PRs. Should be a good race.

Oh I hope so. Younger dude, just needs a few competitive races under his belt and he's going to be a monster.

I just hope he doesn't cause serious injury to himself or shorten his longevity with all of these massive training runs, but he knows what he's doing.

Curious if they will run the Marathon Project as more of a TT, or a championship style race for the win.

I don't think there is any way you can look at his last month of absurd mileage and massive hard/race effort runs and think "he knows what he is doing"

He is in incredible shape right now but no doubt he is well on his way to being the next Anton Kurpicka.

I just listened to a recent Running Rivals podcast (Martin Hehir was the guest) and they said Tyler Day was pacing the race at 2:10 pace.
