Polarized Training for Ultrarunners

Most studies that advocate some radical method of training are based on a few untrained athletes over a short period of time. They don't mean much, but they get a lot of attention. Not long ago, there was a study of more than a hundred trained endurance athletes from a variety of sports that compared different training protocols. It last nine weeks, which was as long as they could get athletes to abandon what they were already doing and why several sports were involved. Each group had two weeks of hard training, followed by a recovery week, repeated three times. One group did a version of high intensity interval training, one did a lot of lactate threshold training, one did solely long slow endurance and one did "polarized" training which involved both very long endurance and maximum VO2 uptake interval sessions. The polarized group ended up with the greatest change in VO2max and endurance, which one would expect, as that's what they trained for, but they also improved their lactate threshold more than those who trained specifically for that. It's unknown whether adding specific lactate threshold runs to polarized training would be even better or not.

The training regimen immediately made me think of ultrarunning schedules. Here's what I'd come up with:

WEEKS 1&2

M off
T 90 minutes total averaging 75% max. heart rate, with half at lactate threshold
W 20 min warm-up, 4x3min hill at 90-95% max heart rate, 35 minutes cool-down, 4x3min hill, 15 minute cool-down (120 minutes total)
Th repeat Tuesday workout
F off
Sa 240 min trail run at 75% max heart rate, with 6-8x 5 sec. uphill sprint roughly every 20 minutes.
S 150-240 min, done as on Saturday.

WEEK 3

M off
T 4x3 min hill
W off
Th 90 min, half at threshold
F off
Sa 120-180 min
S off

To this, I'd add strength training, which I think I described once before on this blog, done as 100 1-meter box jumps. This is the protocol used in studies to generate delayed-onset muscle soreness. I believe that, if one can get to doing those box jumps without DOMS, from training effects, one could probably handle the worst terrain in trail races.

Not Universal, Not Unique

I was thinking of a quote from Brad Hudson's book "Run Faster" during today's run. He said: "Ever notice that when running intervals the first one or two are never the fastest?" And I remember thinking, "No. That's not my experience, because I go into interval workouts rested, I do a proper warm-up and I'm running a challenging pace." I get what he was saying - it's a common experience - it just isn't mine.

Among other aches and pains, I recently developed pes anserine bursitis. It's a pain below and medial to the knee, where you think there isn't anything. If you ask experts, they'll tell you that it takes 4-6 weeks to recover, with no running. I'd had it before, knew what caused it, knew how to treat it (stretching hip adductors and hamstrings, and correcting some running form errors that came from running tired and babying other injuries) and I was recovered in three days. That's unusual, but not unique. I wouldn't tell others to expect a 3 day recovery, however.

Today was a day of hard hill repeats. I was worried, because I'd had two weeks of poor training and a bunch of minor aches and pains, including the bursitis just mentioned, which running fast and on hills could cause to become worse. I'd run the Snake Hill in 3:58-4:14 (four repeats) earlier this year, but my pace had slowed down to about 5 minutes of late and I was hoping to run 4:05-4:12.

I did the first one in 3:37. Oops! All the nervous energy from fearing that I wasn't ready to run fast had me go out too fast. I intentionally slowed the second one. I ran it in 3:40. This was going to be a major problem; I knew I wasn't in good enough shape to maintain that (there's always the thought "hey, maybe I am that good," which usually leads to disaster. So I slowed down, way way down and just "jogged" the next one... in 3:53. The fourth one had me falling apart and I ran about 4:25, barely able to keep from quitting. I couldn't do a fifth one.

So, no... I didn't notice that the first one or two were not the fastest. If I'd the first one in 4:10-4:15, maybe I would have. That's just not the way things work for me.

A Bit of a Whine

It's a miracle that I can run at all, so it doesn't make sense to complain when things get a bit tough. It's also Lent, and you're not supposed to brag about how difficult what you're doing is, nor complain about how hard it is.

But you couldn't do it. And right now, it sucks.

I got into heavy training a couple of weeks ago and now the weather's gone bad just at the worst possible time. Saturday, I did hill repeats for two hours in sub-zero wind chill [and whoever of you it was who honked at me from your white truck: you have tinted windows. No one can tell who you are. But thanks, anyway; I was at a particularly low point]. Sunday was a long run - with speed work - and it was still below zero and I quit early because my arms went numb (and daylight saving didn't help matters). Last night it snowed, so I had to shovel before I ran and I ended up running in snow, still below zero wind chill. Tomorrow's the last tough day, for a few days at least, and it will STILL be below zero and I have to run hills, probably in the dark and probably on glare ice. We'll see.

I don't know how I'm going to get through tomorrow.

I'm doing the Great Lent, 48 consecutive days of minor fasting, and coinciding with heavy training, I've lost a lot of weight. My clothes don't fit. I'm always tired and a little grumpy.

My heels hurt even while I sleep.

I also gave up social media, so I don't have a lot of places to bitch and moan. Okay, so I've done that. [By the way, I had to do a 80 minute software update on my Suunto watch and it erased all my data. I hate that watch so much.]

On to tomorrow.

The $15000 baton relay

Update: The Return of Cool Hand

I did Tuesday's workout as if I were born to it.

"Greyhounds" Workout

The next time I post what I've been doing, this workout will be in there, so I thought an explanation was in order.

The first time I encountered this workout was in examining the training of some world-class 800m runners. I thought it was a typo. Years later, whenever I see it online, there's inevitably a comment from someone saying that "This must be a mistake. It doesn't sound reasonable." Here's a typical Greyhound workout:

10x100m with 5 meter recoveries

See? You immediately wonder if I meant 50 meters or maybe 5 minutes. 5 meters looks wrong.

Think of a dog (a greyhound) running along the fence of an enclosed yard. It runs as fast as it can, suddenly encounters a fence and has to slam on the brakes. Then it turns around and runs the other direction as fast as it can. It does this until it's exhausted or gets distracted. That's what the workout is like.

It's usually done on a track where the 100m race is marked. One runs a sprint in lane 1, turns into lane 2 and sprints back, turns into lane 3 and so on. The beauty of the workout is in the stopping and turning. Having to rapidly decelerate stresses the same muscles you use in sprinting, but in a completely different way, switching from concentric loading to eccentric loading. Runners tend to slow gradually in training; about the only time one runs like this is in a cross-country race where there's a hairpin turn at the bottom of a hill [I have a great story that involves doing that; if we ever meet, ask me about it]. The pivots at the end of each sprint require some agility and work the smaller "balance" muscles, which are also under-used by most runners. It is a completely different workout than running 100m hard/ 100m easy.

Energetically, short sprints use the creatine phosphate/ ATP shuttle. You can regenerate creatine phosphate in less than 5 minutes (usually) and your normal muscle stores are enough for about 45 seconds. Thus the first 2-4 sprints in this workout are mostly depleting the creatine phosphate stores; after this, one goes into lactic acid training - the sprints become more difficult to do and are generally slower as one fatigues. Eventually, after 10-12 "greyhounds," one is slowing enough that the ability to run anaerobically is ending and one should stop before turning it into something else.

It's a tough workout. Invariably, after 5 sprints I find myself thinking that there's no way I can do more than 6. I still end up doing 8-10. It's a workout you don't want to do often enough to get good at it (!) - doing it frequently tends to teach one the "bang" start used by some sprinters (which is good if you're a football player, not for most runners) and then one slows over a much longer distance more gradually; it's the short stop that's important.

Training Log: January, February

At the start of the year, I had some lung issues, so I was unable to run much. Other things worth noting: "strides" are 45 strides (90 steps) in 30 seconds, about 100-120 meters, done once or twice per mile;" "sprints" are done up a very steep hill on a trail (when possible) and are roughly 8-10 seconds; "Mounds Hill" is 0.25 miles up, with 89 feet of climb (6.5% gradient), "Ramsey Hill" is 0.215 miles up with 117 feet of climb (9.5% gradient) and "Snake Hill" is 0.43 miles up with 174 feet of climb (8% gradient).

There's a LOT of niggling injury stuff here, which is expected when going from no running to heavy training at my age and with my injury history.

Is Training a Markov Process?

This is one of the most esoteric of questions, but one I've been mulling over for a while: Is training and racing a Markov process? A Markov process is one in which the conditions at any moment determine what happens in the next moment, but the overall history of how you got to that moment is unimportant. It's actually a bit of a free will vs. determinism question; if every moment decides the next moment, then you have no choice in what happens.

The immediate response of most people would be that, if you run a certain time at a race, it doesn't matter how you got there. The time you run is the time you run and that's that. Of course, if you used performance-enhancing drugs, then all of a sudden everyone thinks it's very important how you got to where you are. So - it's not important unless it is?

I think what's important is where you are in your training. Training responses tend to form a logistic curve:

If you're early in your training, at point "A," then if you race, you probably are going to run about as expected (not all that well, but better than in training). Similarly, if you're late in the training, at point "C," then you can be fairly confident that you're going to race well and within a narrow range of possible times. It's when you're in the middle, at point "B," that things get tricky; you're rapidly improving, so it's possible that you might have a surprisingly good race. I think most runners don't have any idea where they are, because they don't train consistently, but if they did, they'd know whether they're improving rapidly or starting to reach a peak.

This is why, if you see me running, you shouldn't ask me what I'm thinking about.

Planned Recovery

This is the last in the series of a somewhat new approach to ultramarathoning.

I've always run too hard on my easy days. Fitness being a function of the average training load, it's easier to make the easy days harder than to make the hard days harder. The only way I could keep myself from doing that was to make easy days complete days off from running. If I took Friday off, I'd often find myself thinking on Thursday "I can get through this. Tomorrow I don't have to do anything" and on Saturday "I should be able to crush this workout; I've had a day off." Along with the psychological boost, there's a real benefit in terms I've been using earlier: if you run, say, 10 miles six days per week, then a day off increases the variation as much as running a 20 miler - and variance per mile run increases, as the average mileage decreases.

What I've been especially bad at is having easy weeks, except when tapering for a major race or when injured. My best year of running - 35 years ago! - I'd have a moderate mileage week, two high mileage weeks (and I still recall how hard they were), a moderate week, then an easy week with speed work and then an easy week tapering to a race. That six week cycle worked well for me, but I abandoned it and I don't remember why.

Looking at the ultramarathon schedules that are commonly used, for example the Ultraladies, the Relentless Forward Progress,  and to a lesser extent Hal Koerner's Field Guide, they include weeks of decreased mileage. I think the idea is that the very long runs, usually back-to-back, are so stressful that one needs entire weeks of recovery. Many marathon plans also include an easy week every third or fourth week.

What I'm thinking is that, after two high mileage weeks, a low mileage week will become much faster paced (given my propensity to run too hard on easy days) and perhaps the increased speed may lead to the next high mileage week being run at a faster pace as well.

It's too early to tell so far. I've only been through a bit more than three weeks of training, but the "easy" week has been fast. I'm running about a minute per mile faster than I was three weeks ago, but part of that is weather related. From what I can see, I'm about 30% of the way to where I want to be in training in just a few weeks. Of course, the biggest gains come early and it's very early in the season.

It's a promising start, as long as I don't fall apart and get injured.
