Data obsession

Sometimes I get sucked into a coding obsession. I am not even a programmer. But when creating data processing routines I can get into a flow. Improve. Debug. Improve. Debug. The end result is

Lack of sleep
Spent more time coding than I will ever save using the code
Spending a lot of time daydreaming about code improvements

The remedies are to either completely abandon the project or to tolerate it for a while. The enthusiasm ebbs once a certain level of usability is achieved but other people fail to agree what a great thing I have produced … 🙂

So last week I spent a few hours getting Greg’s great python routines to work with TCX files. Did that, and tweaked the plots a bit to my taste. I could have stopped there. In the mean time, I have

Added parsers for the CSV files produced by RowPro and the desktop version of painsled
Added a routine to make “pretty” summary strings, one-line-per-interval pretty strings for painsled CSV files and CrewNerd summary CSV files
Packed everything into a python package and uploaded it to pypi.python.org when people can download and install it
Pedantry alert: Rewrote one of Greg’s for-loops using Python pandas selection tools

The final big thing I want to do is add a concept2 logbook uploader. Then I may even start uploading my OTW rows to the logbook.Painsled is great, but you have to use the Concept2 utility to upload your rows to the logbook. The C2 utility is fine, but only works if you have your PM3/4/5 with logcard connected to the computer. With my utility, you should at least get the basic data (total time, total distance, date, weight category into the logbook.

Anyway, for the adventurous: https://pypi.python.org/pypi/rowingdata

There will probably not be more than three people in the world who may find this useful. I wonder who number three is.

Anyway, here is today’s row in all it’s glory:

Workout Summary - D:tijdelijkcrewnerd-2016-03-30.csv --|Total|-Total-|--Avg--|Avg-|-Avg-|-Max-|-Avg --|Dist-|-Time--|-Pace--|SPM-|-HR--|-HR--|-DPS --|09908|53:13.0|02:41.1|19.5|142.8|174.0|09.5

No intervals summary, because I did this row as one big “Just Row” in CrewNerd.

I was a little time pressed, doing this row between work meetings, so it was shorter than I wanted. I did the 10 strokes on/10 strokes off again, experimenting a lot with stroke length and rate.

Coming Saturday I will row a test 6km trial against the 15/16 year olds in pairs. Not sure who should theoretically be faster. I hope I will win.

Here are two other highlights:

Surprise session and day off

Sunday

The plan was to row the double with Romana. The girls would do a hard 4k and we would paddle next to it in the double.

Reality was different.

There was such an amount of chop that it was irresponsible. We didn’t realize it at first, but when we brought out the girls’ singles and put them in the water, they were swamped immediately.

So we decided to take a quad. So suddenly I was to stroke a 4k.

The lake was unrowable. We reverted to the river/canyon. Romana in bow seat. The girls Iva and Lenka in 2 and 3 seat. I stroked. In the end we did it as a 2x2km with a 2 minute rest which is needed to turn the quad.

I stroked a comfortable 27spm on the tailwind part, and a fine 28spm on the headwind part. Not too taxing for me.

It was great to stroke a quad again.

After that, we wanted to see The Boat Race on TV, but we discovered that we don’t receive any channel that broadcasts it. Eurosport had other sports.ČT Sport didn’t have it either. And the bbc.co.uk website declined to stream the images outside the UK. 🙁

Monday

A rest day. Romana, the boys and I did a short hike to a nearby 14th century castle. Thoroughly enjoyed this rest day …

Back home: 2x3km and easter traditions

The trip home was uneventful, luckily. Here’s a picture of our trailer ready to hit the road.

Before we left, I took a final picture of the canal. Empty because of lunch time.

Racice 002.JPG — Rowing canal at Račice. Mirror flat water.

We had become used to the mirror flat water. We were spoiled.

Today’s training was a 2x3km “at head race pace”. After a full week of rowing, I am looking forward to Monday’s rest day, but this one had to be accomplished.

We headed to the rowing club, prepared the boats, and headed for the water. Romana and the girls took it to the castle, to avoid the chop. I hesitated, but then I decided I would row on the choppy lake.

The goal was to row a 2:13 or faster average and at least 27spm. I didn’t manage to row higher than 26spm in the first 3km (tailwind). In the heavy chop the stroke rate went down and I couldn’t even get my heart rate up.

A two minutes rest and then battling into the headwind. I had done the tailwind section in 2:08 pace, so I didn’t want to be slower than 2:18 in the headwind, and I had to work hard to achieve that. Still, I am glad I gave myself that pace target, because it gave me an incentive to keep going, even on tired legs. Even managed to get the stroke rate up to a decent 28/29 spm in the final 1000m (counting strokes).

Oh, how we’ve been spoiled on the mirror flat water in Račice. I will upload a video soon to show you.

Here’s the same picture, but instead of distance I have time on the horizontal axis.

In the cooling down I started to accelerate because I wanted to stay ahead of Romana and Lenka in a double.

After the session, I went to our lake shore with the boys to collect young willow branches.

On Monday, we will celebrate a special local Easter tradition.

In the morning, men spank women with a special handmade whip called a pomlázka (in Czech) or korbáč (in Slovak), in eastern regions of former Czechoslovakia Moravia and Slovakia they also throw cold water on them. The pomlázka/korbáč consists of eight, twelve or even twenty-four withies (willow rods), is usually from half a meter to two meters long and decorated with coloured ribbons at the end. The spanking may be painful, but it’s not intended to cause suffering. A legend says that women should be spanked with a whip in order to keep their health, beauty and fertility during the whole next year.^[4]

An additional purpose can be for men to exhibit their attraction to women; unvisited women can even feel offended. Traditionally, the spanked woman gives a coloured egg (kraslice) prepared by themselves, invites to eat and drink as a sign of her thanks to the man. If the visitor is a small boy, he is usually provided with sweets, and a small amount of money.

You can buy the whips in the supermarket, but the idea of course is to make them yourself. This is the idea:

Our end results were quite good. Actually better than this picture, because we did the handle part from willow branch and not with tape. The boys did most of the work themselves.

Tomorrow, I will do a nice outing in the double with Romana. Then we’ll switch on the TV in the club house and watch The Boat Race.

Račice day 5: Intervals and leaving

A quick blog between the shower and loading the trailer.

The workout was 45 seconds “on” / 1 minute rest. Again I focused on a “light” catch and a clear, clean tapdown which works wonders to get up the stroke rate. In the final 6 intervals I played a bit with the stroke rate to get down to head race stroke rate.

Took a video but I will not get to processing it before the weekend.

Quite happy with the paces achieved.

I was thinking of adding some processing to automatically detect intervals and create a summary table, but then I remembered that CrewNerd can export the summary as a CSV.

Račice Day 4: Insomnia and steady state

Our group is staying in two bungalows at the 1500m mark. The boys are sleeping in one bungalow, and the girls, one trainer and myself in the other bungalow. The boys bungalow is a bit unlucky. On Monday, the first boy got a mild stomach flu, so he stayed in bed on Tuesday. He was better on Wednesday, but then the next guy had the same symptoms.

I went to bed at 10pm on Wednesday evening. Some time between midnight and 1am I woke up because somebody was knocking on the door of our bungalow. It was Lubos, my single sparring partner of this week. He had a terrible, unbearable earache and wanted to see a doctor. So I get my clothes on, found the nearest hospital in the navigation app and we drove to nearby Roudnice nad Labem.

They couldn’t help us there, because they had no ear/nose/throat doctors on the night shift. They explained that by saying they’re a small hospital, and told us to go to Prague or Ústí nad Labem. Both were about a 30 minute drive so I settled on Prague. Bigger city, probably bigger hospital. Lubos was in great pain.

We arrived in Prague and quickly found the night sister on the ENT ward, who woke up the doctor. Otitis Media, was the verdict, probably as a result of a cold. The doctor punctured the ear, which gave immediate relief, and gave Lubos a recipe for antibiotics, which we picked up at the nearby night pharmacy.

We were in and out of the hospital within 30 minutes. Back at the rowing center at 3am. It took me another hour to get to sleep again, and then I slept until 7.

Lubos kept apologizing, but I don’t know what for. He was in great pain and he was helped. It was an interesting excursion and the problem was quickly solved.

Anyway, it means I will have to train alone, because Lubos obviously has to rest. But that’s no problem now. A few more rowing clubs have arrived, including an interesting Swedish group. I chatted with them after the training. They are a mix of national squad members and club rowers who are staying three weeks in Račice. Some of them will compete on the head race in three weeks.

The morning session was 16k of steady state. I made it more interesting by rowing it as 2k intervals with a 1 minute rest, and doing rate ladders 18/20/22/20/18 per 2 minutes.

The afternoon session was 10k of technique. Romana cycled next to me for 2k and I did what she told me to do. Then I repeated that. I stopped after 8k. Good enough.

Perhaps I should have gone to a pub or a night club in Prague. 🙂

Račice day 3 -ANP training

Tuesday afternoon. A technique session. I did the whole variety of technique exercises.

Wednesday morning. I looked on the wrong data in my training plan, so instead of a planned steady state session, I did my first ever “ANP” (Anaerobic Power) session. This is one of the four training types from the Olbrecht book. It is supposed to be at >100% of race intensity, short bursts with short rest. The overall training volume is short and it is usually followed by a long, low intensity steady state. That looked quite close to what we rowers do quite frequently, namely “10 strokes on / 10 strokes off”. So I decided to do 4km of 10 strokes on/10 strokes off, followed by steady state. Here is the data:

After that a long teleconference with Brussels. My partners are just one subway stop from the Maelbeek station, so you can imagine the emotions. Everybody is OK, luckily.

I didn’t have to go to Brno, because our Brussels based customer canceled his business trip, for obvious reasons. Being really tired from the intense training, I decided to go and explore the region. Visited the old (12th century) Rotunda church on the legendary mountain Říp (the climb was a 30 minute brisk and steep climb, so I count it as a short recovery session) and visited the town of Mělník.
