Thursday – 3x20min Steady State

Again compromising with my training week because of the workshops. Also, I found out yesterday that my own single doesn’t fit on the big trailer to Brandys. As I don’t want to drive my own trailer, I will have to race in a club boat coming weekend. So I will do my Friday’s workout on Friday morning, in my own single, and it will be the 2x3km that I had planned for Saturday.

I will take a day off on Saturday, visiting Prague with my son. Then race on Sunday.

Today was simple. 3x20min on the erg (no time to go to the rowing club) and I let the power vary a bit – but tried to stay around 180W.

Lactate was 1.9 mmol/L after 40 minutes and 1.5 mmol/L (!) after 60.20160908-191755-sled_2016-09-08t19-51-30zgmt2-strokes20160908-191828

A hard workout 3km/2.5km/2km OTW – glad I have that one behind me

I got to see the sunrise today. That was a really nice reward for having to get up really early. I had the alarm clock at 5am, because my work schedule wouldn’t allow me to train in the evening (business dinner) and to do a session before work, I needed to push off the dock a lot earlier than my usual, relaxed morning sessions at 7am.

Pushed off at 5:53. Things take a bit longer at the rowing club when you’re the first one there, have to unlock doors, etc.

I knew this would be a hard session. In this mesocycle I am doing one or two of these “hard endurance” or “L2” sessions a week. After a summer of sprinting and then letting my fitness degrade, my body hates these sessions. I know it will get used to it, but right now I would prefer any short and sprinty stuff over this. Both types of hard sessions are painful, but I am not mentally prepared for the “long hard distance” pain that sets in slowly but drains you long before you have the end of the session in sight.

So I am allowing myself pretty long rest periods between the intervals, gradually shortening these rests as the weeks go by, to be ready to do a 6km race in October. Today’s session was a classical Pete Plan (Wolverine Plan) session: 3km / 2.5km / 2km at 5 minutes rest. But on the water, each 500m takes 20 seconds longer, so this is actually harder than OTE.

I wanted to do the intervals with increasing stroke rate. The race pace will be 28/29spm, but I cannot do that right now, so my plan was to do the 3km at 25spm, and then increase by 1spm with each interval.

After a 2.2km warming up I turned the boat at the northwest end of the lake and took off.

Summary for your location at 2016-09-07T04:27:43Z: Clear. Temperature 54.46F/12.4C. Wind: 1.18 m/s. Wind Bearing: 39 degrees

I don’t fully agree with the weather report, though. I think the wind speed is pretty accurate. The kind of headwind that you feel, but you (wrongly) get the impression that it doesn’t help you much in the tailwind parts. I took the liberty to change the wind bearing from 39 degrees (NE) to 340 degrees (NNW). I felt that this was a straight head/tail wind with no crosswind. Wind direction is a very local thing, especially in hilly country.

My HR meter seems to misbehave in the second and third interval. Perhaps it’s time to replace the Wahoo Tickr’s battery. You can also see from the graph and from the data that I was a bit more conservative with the stroke rate than the plan. I really was afraid I would give up the session. The distances seemed long. In the end I managed, even without too much stroke counting. Counting strokes for 3000m seems demotivating to me, so I rather pick landmarks and divide the interval in sections. Pass the Lodni Sporty Rowing club. Pass the playground. Pass the slight turn. The restaurant. Rokle. That’s three km divided in 5 sections that are not equally long, but each of them is short enough to be manageable.

When counting, I started to practice something I saw an American Olympic sculler do in a video. She counts ten strokes. Then she doesn’t count for two strokes. Then ten strokes again. Of course you count two strokes, but it nicely disconnects the series of ten. Ten strokes always seems doable, and by separating the strings of ten, I tend to focus more on the ten itself then if it is the third set of ten out of 11 sets of ten. I am not sure if I am expressing myself clearly, but you should try it.

I used to count like this: 1-2-3-4-5-6-7-8-9-10-2-2-3-4-5-6-7-8-9-10-3-2-3-… etc. I would know exactly where I was, and I would in general be frustrated by seeing that after 50 strokes the meters countdown was less than 500m.

Now I count: 1-2-3-4-5-6-7-8-9-10 nothing nothing 1-2-3-4-5-6-7-8-9-10 nothing nothing etc … and by some magic the meters seem to go by faster. Try it. It might work for you as well.

Synek’s race & Lactate riddles

Synek’s race

On Sunday I proceeded to make my plan for this week. As usual.

The only thing is that I forgot that my kids will be racing in Brandys nad Labem, a regatta organized by the Brandys rowing club (president Ondrej Synek), and it doesn’t make sense to be the only family member remaining in Brno, let alone that my single would travel to the race venue anyway because Lenka will be racing it.

So my plan to do a 2x3km row on Saturday and a recovery run on Sunday would be difficult to execute.

To make things worse, I am in a full week of a training program. At our local site, luckily, but it means that I am doing the training from 8am to 5pm and have to do my day to day job before 8am and after 5pm, which leaves little time for training.

Plan goes to the dustbin. I signed up for the Masters 1x race on Sunday, and designed an alternative plan.

Sunday

On Sunday I did a recovery bike ride with the family. Nothing straining. Just a nice ride. Didn’t bother to wear a heart rate belt.

Monday

The plan (and the revised plan) called for sprintervals, but there was too much wind to go OTW. Also, I had a bad night of sleep from Sunday to Monday, so I decided for an additional rest day.

Tuesday

Today’s workout was 6x10min at 190W, with lactate measurements after each 10 minutes. After last week’s step test, this would confirm that my lactate level at 190W would stay steady and below 2.0 mmol/L.

The reality was different.

Here is the table with the record:

time Power Lactate HR Max
10 193 2.3 160
20 194 1.9 162
30 194 1.8 168
40 195 3.7? 173
50 190 2.7 171
60 191 2.8 174

The first measurement was a bit high, but I concluded that could be a “start” effect, and as soon as lactate “burning” would set in, my lactate level would stabilize. I seem to remember something to that effect described in the Olbrecht book.

The measurements at 20 and 30 minutes seemed to confirm the theory, so the 3.7 mmol/L after 40 minutes was a shock. Perhaps a failed measurement? I didn’t have time to redo the measurement because I had to go do another 10 minute interval.

After 50 and 60 minutes I measured clearly above 2.0 and my perceived exertion was in line with that. I seem to be able to detect increasing lactate quite well. It suddenly seems harder to hold the required power. Until 40 minutes, I had to force myself to go below 200W and I ended up rowing a few watts above the required 190W and things felt easy. Also, it was easy to reproduce stroke after stroke very similar Watt numbers. When I get tired, there are more power oscillations, and I feel it.

The 40 minute measurement is probably a faulty one. I didn’t feel tired yet.

My theory is that I was too close to the threshold. My hypothesis is that my reduced fitness has shifted my threshold to the left and also makes me produce much more lactate when above the threshold. So I was rowing on the edge and moved over it after 40 minutes. As soon as I moved over the edge, lactate shot up.

lactate3

As a scientist, I would feel uncomfortable with this level of speculation and hypothesis, but I accept that Lactate measuring, as everything in sports science, is as much an art form as a science. If you have to do a full battery of tests and measurements before you make a decision, you lose too much valuable training time.

I am retreating to 180W for my steady state rows and will measure lactate after 60 minutes.

Saturday: 2x3km – head race preparation

Another beautiful summer day at the lake. The temperatures are not so hot any more. A pleasant 25C and almost no wind. Flat water, except for the wakes that I had to row through.

First a 2km warming up:

I did 2x3km at 3 minutes rest. Yesterday’s bike ride was more exhausting than I thought so I was wondering how to do this workout. In the end I decided I would be happy if:

  • I would row both segments at faster than 2:13 pace
  • I would focus on technique and boat run, achieving the pace through a light stroke at 25spm, not using power

I succeeded.

Looks like 1:55 equivalent erg pace on average, which I think is about right. Some wake in the first interval. I pushed a bit harder in the final 250m of the second interval

Workout Summary
--|06000| 25:50 | 2:09.1| 25.9| 174 | 186 | 9.0

After that I was very tired. I did a very slow row back to the club:

At one point I had to speed up a bit to stay ahead of the tourist ferry. Almost bumped into a swimmer there. I stopped and gave her a lecture on the rules. No swimming more than 150m from the bank. Sometimes I am like that. I am generally friendly and greet other lake users, but this lady irritated me. I was trying to stay away from the ferry trajectory and she just came swimming into mine.

At our rowing club, you have to carry your boat uphill after the training. This was one of those sessions where I really wasn’t looking forward to that. I did everything in slow motion. Carry boat. Wash boat. Back to the dock for the sculls. Bring boat inside.

In the mean time, our club house and park was being turned into a wedding chapel. We make a little money to pay for new boats and repairs by renting our beautiful location for team buildings, parties and weddings. I have mixed thoughts about that. Usually all goes well and everybody is happy. Sometimes the neighbors call because of too loud music, or you arrive at the club for your morning session and have to climb over drunk people sleeping in the grass.

But these folks seemed to be very well behaved, happy and nice. They are very lucky with the weather, and will do the ceremony on the grass. I had a little chat with them while I was locking our boat hangars. I also casually mentioned that the lake consumes a drunk swimmer now and then. I hope they have a very good time and no accidents happen.

Friday: A little longer commute

I was looking forward to this. The plan was to leave work early and take a long cycling route around the city. I tried to plan it as flat as possible, but in Brno this is difficult. The climb up to Líšeň was much longer than I expected. The climb to Vranov was as expected.

To make this a recovery workout, I slowed down really a lot on the climbs. I also rode in a light gear and tried to have my cadence high during the entire ride.

Sprintervals with long rest – OTW

Finally an OTW day again. Couldn’t do the row in the morning, as it is the First Day of School after the vacation, and I didn’t want to miss the breakfast with the kids this morning.

Arrived at the lake around 5pm. It was warm, around 28 degrees, and the lake was calm. There were fewer swimmers and paddlers and other recreational vessels than during the vacation, but there was still enough for me to be nervous and wear the mirrors.

The problem is always the same. Nobody estimates the rowing boat’s speed correctly. There is a very simple way to determine if you will pass in front of or behind a vessel, or are on collision course. If the other boat is moving forward relative to a fixed point on the shore (horizon), you will pass behind it. If it is moving backwards relative to the shore, you will pass in front of it. If the horizon doesn’t move with respect to the other boat, you are on a collision course. Assuming none of the vessels changes course or speeds up/slows down.

I was still struggling with the SpeedCoach workout menu. I wanted to do 20×30″/60″ rest. Being lazy, I thought I could program that as 10x(30″/60″/30″/60″), so the rest periods would also be captured. However, I forgot to change the rest between the series. I discovered that after the first two 30 second speed bursts, when the SpeedCoach went to a “break” of 10 minutes. I stopped and reprogrammed, reducing the rest between “sets” to the minimum of 30″. I guess the right way to program this workout is to do 30/60/30/60/30/60/… etc, at least if you want the rest period to be recorded. Here are the plots for the 18 intervals I did after reprogramming:

The setup of the SpeedCoach confused me in such a way that I forgot to sprint during one of the 30″ intervals.

I didn’t go all out on the sprints but tried to reach a good boat speed by technique, especially trying to accelerate slightly in the last part of the recovery. I think I am seeing a boat speed improvement doing this, but it is too early to proclaim victory.

erg 004

4x2km with difficulty

I am in the first week of a 6 week block with a focus on “Aerobic Power” (or AT/VO2 training zone). Today the AEP training was the good old Pete Plan 4x2km, at 5 minutes rest. Here are the training zones I am referring to:

Definition of Training Zones
Definition of Training Zones

The Pete Plan way of doing this is to take a target power (or pace) and try to hold it, then go all out in the final interval. The session average is the new target pace.

A year ago I read books on rowing training (for Masters rowers) and a book on swimming training (Olbrecht). This year I am reading “Watt-Messung im Radsport und Triathlon” (English original “Training and Racing with a Power Meter”) by Allen and Coggan, the guys behind TrainingPeaks.com. The book is focusing on cycling training. They have a different philosophy on intervals and recommend to continue doing the intervals until you are not able to do it at a minimum percentage (of Power) of the third interval. Yes, the third interval. Not the first or the second, but the third. The idea is that in the first two intervals you are searching for the “right” power and in the third one you have found it. Then you continue until you cannot hold

  • 95%-97% of that power for 20 minute intervals
  • 94%-96% for 10 minute intervals
  • 93%-95% for 5 minute intervals
  • 91%-92% for 3 minute intervals
  • 88%-90% for 1 and 2 minute intervals
  • 85%-88% for 30 second intervals

For rowing on the Concept2 erg, where you can keep your Watts in a very narrow band from stroke to stroke, it is easier to find the “right” power already in the first interval, but I decided to stick to the book’s “third interval” rule. In cycling, the power meter swings much more than in OTE rowing, so I guessed that I needed to row with less constant feedback. To simulate that I covered part of the PM5 so I would only see heart rate and meters left,  then checking the average power during the break.

So a 5% drop signals the last interval. When executing the workout I didn’t reread the relevant section of the book and I wrongly remembered a 10% drop. Here is the result:

erg 004

So in Watts, this is

  1. 244W – 104%
  2. 242W – 103%
  3. 234W – 100%
  4. 219W – 93%

It was a very hard workout. I wanted to stop after 2 intervals.

A few pictures have emerged from last weekend’s regatta:
