What "Risk"?! The "risk" of running a sub-optimal marathon or DNFing? It doesn't strike me as something to be overly concerned about. On the contary achieving your best marathon performance requires risk taking, pushing yourself to you absolute limits.

So genuinely, is there any evidence out there to show that you can't chase a second marathon PB after going for it the first time? I know that the world and it's mother thinks its the case that it is not do-able, but I've yet to see or hear of any actual evidence to back that up. Without that, it's no more than received wisdom that nobody questions because "it's obvious". I don't run straight marathons these days, as you probably know. But I have attempted much longer races "every couple of weeks" quite frequently (And I'm guessing that the reason you're skeptical that a full effort marathon every couple of weeks is because of the distance... if so, I'm presumung that you'd accept that distances longer than marathon should at minimum be equally difficult to race as closely, if not more so). If you want to know about how that worked out I'll report that back for you no problem.

Seriously though I personally wouldn't heed scientific studies in these matters anyway because so many elements vary in different people. I think it's possible to run marathons close together very close to full potential. I'd imagine someone like Krusty or myself could run 2 2.35 within a couple of weeks maybe even 2.33 but doping into pb range especially when that range is well established wouldn't be possible. It's the mix of distance and intensity not the distance alone. I found 100k easier to recover from in some ways than a pb marathon but maybe that was because I didn't dig a deep in the 100k. That 100k left me sore for longer but energy level rebounded quicker. That could be a mental thing of course but recovery is a lot to do with attitude anyway I believe. Basically as in all these matters everyone is different.

RayCun wrote: » This study shows 8-12 weeks for skeletal muscle damage to be repaired after a marathon. In general, running a hard marathon is known to cause large degrees of muscle inflammation, high levels of stress (acute elevation of cortisol), and so on. We also know that there is such a thing as overtraining syndrome, which is caused by subjecting your body to too much stress without sufficient time for recovery. For me, that is enough reason to think that the received wisdom is correct, and the burden of proof is in the other direction.

Krusty_Clown wrote: » Sorry Enduro. Work stuff happens! And to be fair it was a genuine suggestion with a light dusting of sarcasm. All theories (or counter-theories) start with a sample size of one - so if it's something you believe strongly, why not be that one? And yes, I'm fully aware it's quite a distance from your typical endeavour (hence the tongue in cheek). By the way, to do Magness and Marcus justice, I don't believe they suggested in the podcast that you cannot chase consecutive marathon PBs - this wasn't the subject of the podcast, which was more specifically related to marathon success by way of motivational drive and focus.
Krusty_Clown wrote: » Without a firm time-banding, the question could mean a wide variety of things, but if the proposed time-frame were a couple of weeks (which was the piece of my post you quoted originally), then I would suggest that this would be an unrealistic proposition for most runners. Speaking from my own experience(sample=one), targeting a marathon improvement is an undertaking that takes 10-15 hours of training per week (plus supplementary strength work) for a period of 12-22 weeks. That training culminates in a body of effort that (like many other events), comes at a significant cost in terms of health and physical damage. In my view, it is this damage that you need to recover from, before you can set out to repeat the process. The keyword in that last sentence though is the word 'repeat'. If you haven't done anything different - any supplementary training (beyond your damage repair), how can you hope to run even faster than you did 2-3 weeks previously? Improvement needs training stimulus and training doesn't happen instantaneously. I have no evidence to hand to support the ideas that you need to recover from a marathon and that you need to train to improve your performance, but if we're talking an interim of just a couple of weeks they're pretty self-evident proposals.

Itziger wrote: » For those doing a fairly traditional LR, with or without MP. What do you do on the day before? I suppose there'll be at least two camps, those who do a Slow LR and those who some some quality in it. I'm now looking to incorporate M paced stuff into mine. Started with 12k and did 15k last Sunday. I'm just curious what people do the day before. I tend to do a medium length easy. Will up the distance a bit, but not the intensity. Might get up to 21 or 23k. Thoughts?

Itziger wrote: » Oh, and let's not forget Eau Rouge, from these parts. Big PB in Berlin, fast and flat. A minute or so faster in Dublin 4 weeks later. What if he'd done another one four weeks after Dublin? One of the reasons he didn't is almost certainly because he told himself he couldn't. But how do we know? Maybe in 50 year's time, the new fashion will be to do 4 marathons in 6 weeks building up to a shiny new PB in number 4. Enough of that. Training for this weekend? Any interesting variations out there in the sub 3 world??

I had planned on doing the Berlin/Dublin double myself, but like you, the goal would have been to hammer it in Berlin, and then run Dublin with a view to the National Champs/team-specific goals. Interesting that taking the pressure off could have been a significant contributor (less stress, lower HR, longer before you tip over that threshold). Could you have run that 80 second PB two weeks earlier (maybe skipping the 6 pints )? Are you doing a spring marathon?
