Forums >General Running>Yasso's
Wait a minute. I thought the deal with Yasso is that if you want to run a marathon in xx h:mm, you run repeat 800s in xx m:ss (in other words, a 3h:40m marathoner runs Yasso 800s in 3m:40s), not 800s at your marathon goal pace. Am I wrong about this? (probably )
110% agree, but it's kind have gotten sold that way to the public.

Is it? Or do a lot of runners take it that way? Or do a lot of writers-who-aren't-really-runners read the original articles and then make it seem that way?
On your deathbed, you won't wish that you'd spent more time at the office. But you will wish that you'd spent more time running. Because if you had, you wouldn't be on your deathbed.
Bottom line no matter how fast you run your Yassos, keep your cadence at 180+/-1 and give 101%.
But even that's flawed. I once did 6x800 in 2:20~2:25. But plug any of my PRs into any racing calculator, and you'll quickly see that I could never ever ever run a 2:20~2:25 marathon. Plug a 2:20~2:25 marathon into McMillans, and all of the times for the shorter distances crush my PR's. So I personally am calling BS on the whole thing. Other than the fact that repeat 800's are a killer workout.

101% agree...
For me, Yasso 800s predicted a marathon time that is way way faster than my physical/genetic capability.
I do know you are suppose to do 10 intervals not 6. But when so many people use it as a successful predictor its kind of hard to call it bs. I would not be for or against using it and realize not everyone follows the norm.

I still like 800s and 1000s for marathon training, but it's polishing stuff. It's great for VO2max. I keep recovery short, 90sec for 800s and 120sec for 1000s. This keeps it more aerobic. The best marathon predictor I've found is mile repeats (with a 200m HR - equalizing lead-off) at 163-165 BPM...this works because I know that this is about the HR I can sustain for a marathon. With long 400m jog recoveries, I do 4Xmile the week before a marathon, during taper, and darned if the pace I run for these miles isn't usually spot-on to my marathon.
A lot of pressure in the middle of those shoulders / And we ain't gettin nothing but older / Ain't nothing change but the day we run from / But nobody knows that better than you,huh
Also, the thing about all these calculators and predictors is that they are assuming that you are properly trained for the distance in question, with adequate volume over time. So, the Yasso 800's are going to be more accurate for a more seasoned runner than a runner who has built up to 15 MPW in his/her 2 months experience.

Hey Yasshole--nice disclaimer, damn you must be a Michigan grad! Did you hear the latest from A2 Spring graduation will take place at Rynearson Stadium (EMU) due to the construction at the Big Mess--I mean House. Causing some very unhappy campers.

A specific HR range like that isn't really for everyone. Just so that some older runner doesn't go try to achieve that range and experience exploding heart syndrome.

Jeff, I have TWO degrees from Michigan and never graduated in the Big House. I'd been to enough graduations by that point and celebrated in Good Time Charlie's instead.
