Has anyone noticed LSD helps them more in mid D events than the distance events?

LSD helps as long as I’m not tripping too hard.

I prefer cocaine for running

I experienced what you're talking about when I experimented with higher mileage (for me it was 50-60, up from 30-40), and I think what is happening is a lack of anaerobic endurance. No clue though, not an exercise physiologist.

I really came here to hear the results of LSD on running performance. Didn’t realize we were talking about mileage

here's the way i look at it:

both a middle distance runner and a long distance runner need to be aerobically fit, and both require specificity. 

faster mileage can provide some specificity to a long distance runner, but 6:00/mi "easy runs" aren't really much more helpful than a 7:30/mi run to someone who is racing below 4:00/mi pace. so the middle distance runner can run as slow as they want on regular runs as long as they're getting volume and cranking the speedwork that provides the specificity.

"well snowdays, if you're such a genius why don't any pro middle distance runners run 150 slow miles per week?" 

yeah, they don't. the catch here is that for the mid distance runner, the aerobic strength doesnt even necessarily need to come from running at all. running a billion slow miles is time consuming and more of an injury/load risk than cross training...

hence why there are so many 20-35mpw 800m runners these days who are basically long sprinters that do a fair bit of crosstraining. 

LSD helps to grow your capillaries, which helps your muscles and lungs move and receive more oxygen. It also teaches your body to use its nutrients more efficiently, which is less important in MD but important nonetheless. Run a mile race in a heavy caloric deficit and understand what I mean.

Middle distance is all about anaerobic threshold and being able to maintain a fast pace in heavy oxygen debt once you cross deep into that threshold.

The more efficient your body becomes at utilizing oxygen, the lower than anaerobic threshold is going to be.

About a year back I stepped away from competitive training and just ran roughly 60 mpw of 6:30-7:30 miles with the occasional tempo effort or stride session for 4ish months and came back and destroyed my highschool PBs 800m-5k without any sharpening. There’s definitely merit to it.

First of all, it matters greatly whether you are a 400/800 type or a 800/1500 type. They need to be training differently.

The body always chooses slow twitch fibers first when moving. When enough force is applied more type 2 fibers will be recruited. If you go at a maximal effort for short repetitions with equal or greater rest than you will not be effectively training type 2 fibers aerobically which becomes progressively more important as the race goes on especially after 60-70 seconds in when the aerobic share becomes the predominant energy rebuilding method. If you are a 400/800 type, this is especially important.

Even though specificity is important it will not always trigger the physiological response you might be looking for.

For this reason, I don't agree with the slow / fast polarized training model. You might see a better result in an 800 than you would a 5000 using this kind of training but that might be because it has less of a negative impact due to the higher anaerobic percentage rather than it being the best way to train.

LSD has been hit or miss on my runs, albeit I only have a sample size of 2. One was one of the greatest runs of my life where I didn't feel tired at all even though I was running close to all out. I only realized I was going hard because I got to the top of a hill and noticed I was breathing harder than the trees around me. It felt super primal and was a wonderful experience.

The other time I just felt sluggish for most of it, thought I was probably a bit dehydrated and it was close to 100 degrees. Maybe only doing it on cooler days and during the sunrise would work best.

Twice as well. Both were nice but also a bit overstimulating. 40 min run felt like 10 hours.

I tend to feel very anxious during the come-up, and once I ran

Whoops, accidentally hit post. I tend to feel anxious on the come-up, and once I went on a run to try to combat that anxiety. I agree with other posters in that it was a bit over-stimulating (I could feel the dizziness it usually gives me, and my heartrate was already elevated). Interestingly though, I didn't notice any visuals until I stopped in a field and sat down, and it all hit at once. Would recommend, it got rid of the most unpleasant part of the trip for me. Side note, I've noticed that when I stop on my runs, I still experience visuals (even when sober). Does this happen to anyone else?

the short answer is running economy. when most people think of lsd they think of the aerobic benefits. the biomechanical and neurological benefits are less intuitive but so much more important. mileage is the best way to improve running economy. running economy was shown to be the best predictor for mile times.

as a coach, my suggestion to you is to run as much mileage as you can while staying healthy. build up gradually, listen to your body, sleep and eat well, add in some plyos, recover appropriately from workouts. last one is the toughest to define but generally dont do really hard workouts while setting mileage records. some workouts take multiple days to recover from.

"In races, I can go out so fast and feel like I'm jogging, but all of a
sudden 2/3 into a race I hit a WALL which is a sign of low aerobic
fitness (usually), but I'm not sure why this would happen on such high
mileage."

Don’t take the brown acid.

a few years ago, there was a pretty entertaining thread about running while on hard drugs. I can't seem to find it though.

I heard Nate Jenkins on a podcast and he said something similar about Lydiard training -- that base building with sharpening worked better for guys like Peter Snell and Murray Halberg than it did for guys like Barry Magee in the Marathon.

I too am disappointed. Feels like I've been click baited.

So, you run out of gas a couple of miles in a relatively fast run. That isn't 'hitting the wall' because that is too soon to be running low in glycogen for your high endurance leg muscles. I wonder if it might have something to do with your diaphragm muscle being insufficiently trained? It is used to easy cruising, with no adaptation for more rigorous efforts. In other words, your diaphragm has hit the wall, not your legs.

I think that's a pretty good explanation. The big miles make you very fit aerobically no matter the pace and as long as you're getting in something at or near race pace you'll be in good shape and able to access the speed you have. A long time ago there was thread here about running 140 miles a week, I think that was the one, and someone got on talking about how he'd gone from something like 4:10 in the mile to 3:55 and the big thing for him was doing 130 slow miles each week. On the other hand, if you want to run marathons you may need to do more faster distance runs.
