I assume you know basic powertraining concepts. If not I can refer you to these links:
PMC terminology explained
Before I start with my own PMC I explain some basic concepts in the PMC
chart. The idea behind the PMC is that you track you training load (short term
and long term) based on your TSS (Training Stress Score). Training Stress score
is the amount of stress you put on your body during a particular workout.
Training Stress Score is calculated as follows:
TSS* = (seconds x NP x IF) / (FTP x 3600) x 100
So the components in the formula represent basically how long at what
intensity your workout was in relation to your FTP.
In the PMC you track short term stress (Acute Training Load) and your
long term stress (Chronic Training Load) and your performance (Hence the P in
PMC). By exponential weighting of CTL and ATL to take into account carryover
effects of your training you can calculate TSB (Training Stress Balance)*
The idea is that Form equals Fitness plus Freshness. Fitness is
represented by training load and freshness is the result of rest. Balancing the
two, i.e. balancing ATL and CTL equals Form aka TSB. TSS is the metric which is
used in the equations to calculate ATL and CTL (and indirectly in TSB).
Then comes the question how can you estimate the TSS? Well, some
trainingplans already provide these numbers given the training you do (e.g.
Trainerroad). Another source –which I use- is basically your own experience
powermeter numbers from rides in which you focused on specific training zones.
General rules of thumb can also be applied like these: L2 IF 0.8, 65 TSS/h, L3
IF 0.9, 80 TSS/h, L4 IF 0.95 90 TSS/h, L5/L6 IF 1 100 TSS/h. You can also use
this graph to by using time and % of FTP.
Knowing this is, the question rises what are your goals and what do you
(given you do not have a coach) estimate your CTL needs to be at time X (time
of the goals)? Of course it would be nice to have a CTL of around 120, but for
that you need a lot of training time, because these numbers are basically not
achievable for the time-crunched cyclist. As you saw TSS consists of time and
intensity and for someone like me there’s not a lot of time during the week to
build TSS, so it had to come from intensity. Ideally you would be doing a lot
of time at lower intensity which causes a lot of physical processes in your body
(metabolic adaptions, cardiovascular adaptions, pulmonary adaptions) that
eventually has a positive effect on your FTP (given of course also mixed with
training in other power zones, and given you are a responder to training pulses),
but that’s for the elite / pro guys who earn money with it.
As said a CTL of 120 is basically not possible for a time-crunched
cyclist. All the time spend need to be at enormous intensity and even then you
will not make it given the limited amount of time you spend riding. Also you
won’t be able the hold it in your training because you have your general every
day stress (work, etc.). Given max 5 hours per week during winter and max
average weekly 8 hours non-winter I should be happy with a CTL around 80. By building CTL you should be careful not to build (ramp) it too quickly given your short term training stress (ATL). General rules of thumb to make sure you don’t get overtrained or get more vulnerable for disease are CTL ramp rates of 3-8 points per week. A good example of this you will see below.
My PMC 2013
The story behind
this PMC is, is that there is no story. OK, let’s clarify that a bite more. I
basically did not really plan anything using PMC. I just wanted to see what
this graph would look like and if I would be able to get some patterns from it
and to be able to learn something from it. And you will read below, I did learn
some things ;)
I had a fairly
linear CTL build up from approx. April 10th onwards. 28th
of April was the first big CTL spike from la Philippe Gilbert (160km). This one
had a TSS of 360. After that ride my ATL went to another level and short after
that I did some more intense sessions and another long ride with TSS above 300.
Period where my CTL drops strongly seems like I did not train, but I did. I did
however not incorporate those home trainer sessions in the graph (weather was
bad in that period). The sessions I did certainly did not improve my ATL but
merely stabilized it. After that I build up again and about a month later I was
where I was left off end of May (approx. 45 TSS/day). Around 19-6 you also see
a strong CTL spike from a 360 TSS ride.
End of June CTL
really rises with a top on 4-7. Those two weeks I was on holiday at the Mont
Ventoux, but I did bring my bike. I did some work before the 4th as
you can see in the sharp build-up of ATL. 4-7 I did the Month Ventoux 3 times (also
known as Les Cingles (loosely “The Screwballs”). I
really underestimated that. I ate too little. First two climbs went good. I had
done both sides (via Bedoin and Via Malaucenne) with 250 watt average
(normalised 260). From Sault it went wrong. I got hungry and I did not drink
enough. After a few km’s I completely collapsed. That is, I could only produce 210
(NP) on that climb.
Because of that my
TSB was went straight downward and was very low. My immune system must have
been affected since I got a bacterial infection from a small wound on my elbow….the
result of that was hospitalisation and 3 weeks of antibiotics. No cycling as
you can see in the curve going down to a low of 40 TSS/day.
Then I picked it up
again since I wanted to do a race end of August since my season was already
wasted (remember I had a goal w.r.t winning the local championship but that was
at the time of my bacterial infection). In 3 weeks I tried to manage what was
left, but effect of the antibiotics was larger than expected. I had no power or
whatsoever in those 3 weeks, also not on the race day. I became third in the
race (50m before the finish I was still in first place….) and I had to live
with that (race 1 hour with NP of 309 watt). After that I went on holiday with
the family as you can see from the large drop in the graph (and very positive
TSB).
Learnings I take
from the above:
Biggest mistake I
made was to dig myself in a hole too fast during that Mont Ventoux part (ATL in
one week from 45 to 65. This must have had an effect on my immune system. This
is something I hope to prevent now with better planning of my training and
better monitoring of the PMC.
A positive thing to
see is that I did a 60 min test outside when I got back straight after Mont
Ventoux and with an ATL of 65 (highest of season) I managed to do 325 watt
(whereas before that it was around 300 till 310 NP).
Indirectly: Give
yourself time to recover. This is the hardest lesson, because face it: when you
haven’t been on the bike for a long time, you just wanna go in full gas and
when you see the powernumbers are not what you want them to be than that just
sucks (and makes every ride a disappointment). Riding is fun, and that’s what
is should be even if the numbers are bad.
PMC 2014
Given peak periods I have designed it as follows: I want to peak end of
May / beginning of June. That will be my first peak period. After that I will
decrease my load / intensity to be good at end of July / end of August. W.r.t my training plan I started to think backward from my peak periods. On a macro level I see three periods (until first week of June, but I will explain that later on). As you will see I follow a method of periodization which basically is a build up towards a (desired) peak period. It is base, build and (hopefully) peak.
October 2013 – Half January 2014: Base period
Goal: Very steady CTL of approx. 40 to 45. Content of work is mainly
focused on aerobic intensities (Base I) and later on some more sweet-spot
training (intervals) (Base II).
Quite a long period, but that’s the way it is. When I get back from work
in the evening it is dark and I don’t feel like cycling in the dark (and hours
on Kurt is not my thing). So during the week I will do Trainerroad workouts (2
x approx. 1-1.5 hours). They have great trainingplans so I will use them. The
base period is divided by two periods: Base I and Base II.
Intermediate Base I (Trainerroad): ‘’Following the initial fitness
assessment, this plan emphasizes pedal economy - via leg speed, speed endurance
& varied cadence - and base aerobic fitness. Minor attention is paid to
saddle transitioning, leg strength & brief, anaerobic power bursts, but
this plan is largely devoted to improving form and establishing some base
fitness’’.
Intermediate Base II (Trainerroad): ‘’It allows riders to focus more
intently on growing their sustainable power through consistent use of
near-threshold efforts. The intensity grows somewhat sharply as suprathreshold
efforts are sprinkled in on a weekly basis in the interest of growing aerobic
power in minimal time.”
During the weekends I want to do a longer (endurance) ride from 2-3
hours. Towards the end of February I will start to do more VO2max related
workouts since training races will then start.
Half January 2013 – Half April: Build period
Goal: Very steady build-up of ATL to approx. 50-55. Content of work is
mainly focused on sweet-spot training (intervals), but more VO2max comes into
place as well.
Intermediate Build I (Trainerroad):
‘’As the racing season grows nearer, our focus on improvement of max
sustainable power is split to include more aerobic capacity work (VO2max).
These are the shorter, fairly Intense efforts that can make or break a rider
when the pace kicks up a notch or two, or several.’’
Training of this nature also has a noticeable positive effect on
sustainable power due to the "trickle down" effect of the numerous
training adaptations associated with VO2max work.
Riders who aren't accustomed to this type of intensity can begin to
acclimate to working at this very high level of effort and thereby increase
their ability to ride more competitively. This training plan also incorporates
some less-structured race simulations for variety and pacing practice.
Intermediate Build II (Trainerroad):
‘’With event(s) just around the corner, this training plan notches up the
intensity even higher and prepares you for the forced rigors of riding at race
intensity.
As your ability to endure greater workloads and levels of discomfort -
both physical and psychological - increases, so too must your training stress
if the goal is to continue to improve.’’
Also from March – April there is a more rapid increase in ATL, CTL by
introducing more racing / some longer distances.
Half April – End of May: Advanced Build – peak period
Here the real suffering will start ;), but I should have a solid base by
then so make the step. In this period there will be quite some rides with the
combination of high volume and high intensity. This starts basically from end
of April with the first cyclo in the Belgian Ardennes (which means relatively
short climbs, with (often) steep parts in it). Races I see purely as good
trainings, but if I can feel there’s more in it that just being in the pack, I
will not hesitate. I have to make sure that I earn back the start fee at least.
From half May on I
have to be very careful since I will then be doing a long weekend to ride some
mountains from the Trois Ballons. This is a training weekend to test myself.
This will undoubtedly have a large effect on CTL so the weeks after that I have
to be very very careful. Last weekend is the time trial, and then immediately I
will have to start tapering for Trois Ballons. But to be good for the time
trial I also have to make sure that I taper at least some days before. But that
said, a positive TSB is not necessary to perform well as long it’s not too
negative.
If am be able to bring my CTL end of May to 80 or 90 I hope
be good. Why 80/90? I just want to be able to see the effect of what higher
training stress (and better dosed) will do to my body, and more specifically
for my FTP (2013 my max was 65 just after Mont Ventoux).. So, from April
onwards I have to make sure I have a CTL of around 75 to make sure I do not
make the same mistake to ramp it up too quick.
As said previously, after the first week of June basically my first two
goals of the year are behind me (and achieved I hope) and by then I am going on
a holiday with my family. We do not have that planned yet / no timing nor how
long we will go / nor whether I am allowed to take the bike (if possible).
With that uncertainty in mind and
given the two other goals are end of July and end of August I have decided to
cut my trainingplan in half. For the second two I will make a new plan
(hopefully also) based on my learnings from the first plan.
The above basically
comes down to the following graph:
I have built this
graph in Excel in which I have made my trainingschedule. You may like it as
trainingschedule set-up as well. It is still under construction, but for the
time being it is good enough for me.
I wanted to put it here, but I cannot find a good transfersite. Just give me an e-mail and I will send it to you. Just for the time being.
I wanted to put it here, but I cannot find a good transfersite. Just give me an e-mail and I will send it to you. Just for the time being.
The Excel tool: It starts with the startvalues of CTL, ATL and TSB. I got them from my WKO3+ software. My calendar starts at 29 september 2013. If you want to make sure the graphs keep on working on the ‘Graphical overview’ worksheet then do not delete any rows on the Training schedule worksheet. Rather if your calendar starts at a different date then just put new dates in column A. TSS, ATL, CTL and CTL ramp rates are calculated directly. The rest you put in manually. To make it easy to see where the current day is, you see a highlight in column A.
Idea behind the graphs is that you can zoom in to specific time periods dynamically which is something that lacks in WKO3+. You just see one graph and it’s not easy to go to a specific time period. If you have a lot of datapoints (years) than this graph can become handy.
I have filled my schedule until Trois Ballons. I will have more info later on how to train at that time but that will come (since at that time I also want to go on holiday). It’s not relevant for now.
I correct my
planned data if I have the real data from my rides. If you have any
remarks or things you would like to see just give me an e-mail and I can see
whether to build it in.
