I just thought I would post up whilst I have a chance today, as there has been a bit of renewed talk here this week and a few questions that have come up.
Firstly, would I be quicker if I did X instead of Y? That's difficult to answer, but again I feel that this comes back to to specificity is a very small factor in the bigger picture. If anyone is in the Strava group, Hard2Find has made an absolutely amazing spreadsheet where you can run models and prepare different training weeks and calculate what load it will bring. He is way smarter than me, myself him, jiggy and shirtboy started discussing something like this only a few days ago and its already made and into version 3 or 4. This won't necessarily answer what makes someone quicker, but is probably the best and most powerful planning tool I've seen made specifically for runners, maybe ever.
Which brings be onto a second point, about how I don't specifically feel sub threshold is anything magical, just how my experience from cycling shows it gives the best bang for your buck when it comes to CTL. Now, I have been speaking to a number of old friends who I used to communicate training ideas and sharing of data with when cycling recently, talking to them about training makeup and how it matches or indexes to overall CTL and performance. The difference seemed to range from virtually no difference for me (in terms of getting to a certain CTL was all that mattered, no matter how), to most other people over years of data, seeing some difference in training makeup to get to a certain CTL and what power output that resulted in. So the spread in all of our data, was from about 0% difference right up to 11%. One of the guys had a lot of data on swimmers he coached and found the same sort of thing. His suggested was that a reasonable training plan (he mentioned a Maglischo as a baseline) would probably sway around 5% up and down based on the worst conceivable way to train you could think of (totally unstructured) to the best bang for your buck on around 5-10 hours, which appeared in most cases to be sub threshold.
In case anyone is unclear on what I am saying here, the example might here my FTP might be 300w on a pretty normal looking textbook training schedule, for a CTL of lets say 80. A totally unstructured and just riding/running randomly makeup, might mean I need a bit more CTL, lets say 85, to reach 300w. But it might only take a CTL of maybe a bit less than 80, to reach 300w when doing sub threshold work. Now, one thing it also does appear, as the hours increase and you are less time crunched, the gap looks to probably close a bit and the options you also have of makeup of training, shrinks as well as you will be doing 80%+ or more very easy work, whereas I am sticking by to 75-25%. Why is this the case? who knows, probably all TSS isn't created equal, maybe a traditional training program for any of the aerobic sports has more vo2 work than you need and it tires you out for everything else. Maybe there is another reason.
So the big question is, how does looking at top amateur riders and a bunch of swimmers (which I must stress, is not pulled from scientific studies) transfer to running? Well as I have said before, I have seen the same play out in my own running training. Will it be the same for everyone? probably not, but if we had another data long term, I am sure we would see the patterns there. One of the main problems is runners don't seem to collect data about their own training accurately, which is the main issue. Even if they have years worth of data, they aren't updating thresholds, zones (sorry Coggan, I mean levels) so their actual daily TSS and overall CTL lacks accuracy.
Could you probably ice the cake better if you want to train for a specific event? Probably. If you absolutely only were going to do 5ks, should you try and find a balance of some sort of 5k pace or vo2 max work? Probably. Is it going to be the limiting factor for a hobby jogger? Probably not. The other good thing about training like this is you can pretty much be in peak shape for a range of events , 5k to HM I am within a few seconds of where I want to be.
Right, that's long enough on that, but it's something quite a few people have asked me about lately so thought I would spend some time going through some of where I am at on it.
A couple of other of small notes. I've come to the conclusion this is about 5-8.5 hours max here as the sweetspot, to running this sweetspot stuff, excuse the pun, on this singles approach. You could maybe do a touch less, but having thought about it more I don't think you will be getting the benefit . The third session is the key to creating that extra bit of load, week in, week out that all adds up in the end. Anything much less than 5 hours, realistically you are losing the benefit as it just doesn't give you enough hours for 3 sessions and to keep things fresh and sustainable.
Two other updates. No I don't run 400s anymore. They didn't create anymore or less lactate and they trash my legs for the next day more (I've dumped them for a while and still improving at the same linear rate in the 5k) and I've upped the rest to 2 mins on the 3200 because in the week in the route I run after work, there's a road I need to cross and it takes more than the 1 minute rest to get over it ha ha so literally no special reason. Same with doing 1600s not 2ks. No actual reason other than that I don't have to cross a road mid run. A bit random, but I saw these questions somewhere in the thread a while back and forgot to answer them!
P.S I'm not sure who made me guardian of the thread. There's other guys way smarter than me here. My only skill I think is learning quite quickly what works and what doesn't when it comes to training. If this has all helped anyone over the last 7-8 months, that's awesome. I'm under no illusions myself that I am as good as running as I was cycling, but I am still enjoying it and still improving. I turn 40 next month, fingers crossed I can make it to Sub 16 before then.
