It was a dark and snowy night...

Tuesday was just very cold. Wednesday there was ice, and the mixed VIII had to be cancelled. Today day was warmer, the ice meleted, but as we pushed off a gentle snow started. By the time we got back...

DSC_9225-snowy-rowy

Unfortunately I don't have a photo of either Simon or Fio: both looked like snowpeople after a bit; at least we rowers were moving. And warm(ish) snow beats -4 oC any time. Apparently the night-time coxing was easier, too, because the banks were more obvious.

As to the rowing: 3 reaches, with a very pleasing enthusiasm from the crew for the third reach. Short pieces up to the railway bridge up each reach; from my fallible memory, the best was the last (at 26), the worst was the first (at 28) and the 30 was tolerable. We have a problem with rushing; at 30, the natural rush-rate mostly corresponds to the stroke rate, but we're not properly in control. At 28, nasty things happen (so we should try to do this more and get it right). At 26 there was a pleasing amount of control coming forwards, and more power.

Winter chronicles, continued: Saturday



Reports varied as to the actual temperature, but all agreed that it was f*ck*ng freezing - literally so; at 8 am there was about a centimetre of ice on the river. My car said -10 oC; James H reported the Cambridge weather station at -12. Anyway you looked at it, ergs were inevitable, and that is what we did. The good bit, though, was that we did them as a matter of course.

It was an absolutely gorgeous morning if you ignored the cold: heavy rime on all the trees and absolutely still.

Head of the Cam: Saturday 28th April 2012

hoc-shield Please make a date in your diary for the Head of the Cam Race which is to be held on SATURDAY 28th APRIL this year.

For entrants


Enquiries, prebooking, whatever: please contact the Race Secretary, William Connolley, at wmconnolley@gmail.com / 07985 935400.


Usual format, more details will be available soon. To while away the time, why not look at the Head of the Cam, 2011 featuring links to photos of all crews and videos too.

For us


Chesterton has run this event for some years; make sure that you keep the date free if at all possible, as we will need everyone to get involved and help out with marshalling and race organisation. It is also a fun, social day, it's usually good weather (fingers crossed!) and there will be a gathering in a local pub afterwards. Further emails will be sent round asking for specific roles to be filled, but for now just make sure that you are free all day if you can.

Erging theory

With ergs increasingly in the news as you'll know from your emails, it is perhaps a good idea to put down a few wise words of advice.

Let's start off with a motto: "It never gets easier, you just go faster". In fact that isn't what I want to say at all, but its a great quote!

How not to hate ergs



This is the important bit. Many people seem to approach ergs as a once-a-year test for which-crew-will-I-get-into. Or, they do them so infrequently that every one becomes a quest for a new Personal Best or Seasons Best. This is a recipe for making every erg deeply unpleasant.

JH found Winter Workouts: Why do Rowers Fear the Erg? which expresses much the same thoughts. If you're doing running training, you don't do every practice run flat out, or near flat out. Ergs should be the same: do them regularly, but do most of them well backed off from your PB. They are supposed to be regular fitness training, not episodic tests.

How to like ergs



This is the converse of the above: positive advice as to what to do.

* Pick a piece to do regularly. Record your times / distances. Compete against yourself. Compete against your crew members, in a caring-sharing-group-huggy good way, not in a fanatical race to the top of the table way.
* Join heiaheia, and join the Chesterton group to share your training and see other people's.
* 30 mins is a good piece: long enough to gain fitness. 2k is good as a test piece but it isn't long enough.
* If you're new to all this (a) ask for advice and (b) consider starting off with 10 or 20 minutes before venturing on 30 mins.
* Establish a regular schedule, say once a week (assuming you're doing other training during the week; more if not).
* What works well for me is a "sawtooth" schedule, which is roughly: 30 minute pieces, done at PB-900m, then PB-700m, ..., PB-200m. That forms one set; repeat until fit. Possibly fling in a test piece at the end of each set or two. PB-800m is fairly easy, but you still sweat. PB-200m is hard work. Adjust the exact numbers to suit yourself.

How to do erg tests



However, if you really do want to try your hardest for a test, then you might like to read:

* How to: Pull a 2k test
* Something about rowing..? The 2K
* Dr Southgate's advice column from the old website.

Other good things about ergs



You can also use ergs to practice your rowing technique. Not all of it, obviously. But if you're told, in the boat, that you're rushing the slide; or you're told that you're not separating properly, or your hands-away is too slow: then all of that can be practised on the erg. And usually, if you'd like, someone will be available to coach you.

What we do with ergs



We're doing the ergs to get fit, at this time of year. But they will also form part of the crew selection process come the summer. So I'd better talk about how we compare people.

The current "table" is here, and it is aimed at Head of the Trent type distances, which is not too dissimilar to 30 minutes.

Weight adjustment



In order to compare scores there is a "raw" and a "weight adjusted" value. "raw" is, as you'd expect, exactly what the erg says. But in the real world a heavier person presses the boat down in the water and slows it down a little. So it is fair to correct the scores to a nominal weight. But a truely fair correction is elusive. What I've done is use a 2/9 power law for the weights, and correct against "your weight plus deadweight", where deadweight is your share of the boat+cox weight (which works out at about 20 kg). If all that is gobbledegook to you, all you need to know is that both the raw and adjusted values are judged, but the adjusted ought to have preference, and that in practice, it hasn't generally mattered which we use. If all that made sense but you'd like to know more, just ask, I can mail you the exciting spreadsheet for you to play with yourself.

Let's try to make it clearer by an example. The nominal weight I use is 85kg. So:

* Steven Andrews, who weighs 95kg and has a raw time of 21:12 for 6k, gets corrected to a longer time: 21:44.
* William Connolley, who weighs 73kg and has a raw time of 22:53, gets corrected to a shorter time of 22:07.

In the spirit of "how not to hate ergs" please don't treat the above as targets.

Targets



As a very rough guide, which we will feel free to tear up if we want to, the aim for M1 is an 8k 30 min piece, a 22 min 6k piece [*], and a sub-7-min 2k. All weight adjusted.

Since M1 tend to do more ergs, we have a better idea of their targets than anyone else. Very roughly, I'd say 7500m for 30 mins would be a decent target for M2; that then scales (via more magic; 1.06 power law) to a 23:40 6k and a 7:23 2k.

[*] More exactly, 22:07, but 22 is a nice round number.

Your HOTTmeister speaks

Time to dig out the old ergs again, I'm afraid. The Head of The Trent provides a suitable excuse, but above that: the winter is the time to lay your base for summer fitness. And as I painfully found last night, running just isn't enough. Which isn't strange: rowing and ergs didn't make me fit to run, either.

For the moment we're adopting the innovation of 6k ergs, as it is (a) about the Trent distance (actually 6k is too long, the Trent is probably about a 5k equivalent or less) and (b) it makes a change from half-hours. We're also going to try doing the weight adjustment based on (bodyweight + share of (boatweight + coxweight)) instead of raw bodyweight; this is fairer for the heavy folk and closer to reality. Though up to now, the list of people in raw-erg-order and weight-adjusted-erg-order hasn't mattered much.

In case it isn't obvious, ergs have multiple benefits, apart from the primary one of causing pain. Done regularly, they help fitness, obviously. But they are also excellent mental training for the long haul of headraces, and allow you to see, objectively, how well you can sustain effort; how well you respond in your own mind when your body is begging you to stop.

I expect to update this post as we do more, and/or as people send in scores done on their own. Don't worry, I trust you.

Yet more misc

This was our second night of the new year. I need to work out the weight adjustments, and then sort the table.

Bod Raw Time Avg raw split Weight Weight adjusted
Will W 23:28.5 1:57.4 80 23:10
Paul H 23:46 1:58.8 74 23:03

Misc collected scores


Not yet in table, and/or not entrants, just fitness:

William C 30 mins 7501
Chris W 30 mins 7629
James H 30 mins 8144
James H 6k 21:38.4
Andy S 2k 7:59
James H 2k 6:49.9
Chris W 3k 11:18


2012/01/27


This was our first night of the new year.

Bod Raw Time Avg split Weight adjusted
Steven A 21:12 1:46 21:44
James H 22:11 1:51 [+] 22:00
William C 22:53 1:54.5 [*] 22:07
William D 23:49 1:59 24:14

Avg splits are to the nearest 0.5. These should all be treated as a good hard try, but not necessarily the best that could be done ([+]: marginally worse than the 1:50.5 split for his 30 min 8144 earlier in the week, but he'd been running at lunchtime; [*] worse than my 1:53 split for 30 min last April).

All of these are decent scores, and if SA can get down to a 1:45 split I'll be prepared to call that "heroic". If you're not used to doing erg-arithmetic in your head (alas, a sign of someone who has done too many) then a 2:00 split corresponds to a 24:00 time for 6k, or a 7.5k in 30 minutes.

Did I mention how much we all enjoyed Steven's choice of music? Fortunately his speakers did not match his muscles, so it was inaudible. We need what I believe the youth today refer to as a "boom box" or "ghetto blaster".

The 30 mins table


We're concentrating on the 6k scores now, but Due To Popular Demand [%] here is a 30 min table, too.

Bod Raw Distance Date Avg split Weight adjusted
James H 8144 2012/01/? - 8209
William C 7838 2011/11/11 - 8107
Chris W 7629 [+] 2012/02/02 - 7732 (assuming 80 kg)

[%] Well, James Howard is a very popular chap.
[+] Probably not all-out.

Winter head to head

City have some pix of the H2H up on facebook and here is M1

chesterton-m1-winter-h2h-div1

ripped off and cropped. We're at the bottom of the reach on the first leg. Don't look at the previous pic if you were rowing at 6 or 2 :-).

Results and analysis


Full results are available from City.

202 2 Champs Masters cra m Intermediate 3 8+ 7:31 7:55 15:26

(note heroic performance by Cantabs J18 double).

We beat Champs (M1?) on the first leg, but lost by 8 seconds overall. But we beat their M2. Since we're sandwiched by them for bumps, that is a good start.

It was very windy for the first leg: we went down in 7:04 and came back nearly a minute slower in 7:59. Compare that to the differences for boats in divisions 3 and 4, and their times are much closer, which I think gives an advantage to later divisions. Not just easier rowing conditions with a calmer Reach, but also the boost you get from a tailwind is worth less than the corresponding headwind. Note that Christs M2, in div 3, beat their M1, in div 1. Which is a long-winded way of me leading up to wondering if we'd have beaten Xpress Legends if they'd not been in div 4.

We've entered the Head of the Trent which is, and SA said, like the H2H but with the gap for a rest closed up until it doesn't exist, and then with another 2k thrown in. So time to start taking the land training seriously.

Also, anyone remember the Tidy 2k challenge?

Winter league

Sunday was calm and still but cold and mostly cloudy. Those unfortunate enough to be in the first division got up at unearthly hours and arrived at the river far too early. And the results were...

301 Cantabs Men IM1 8 M1 09:10 1
401 Cantabs Men IM1 8 M2 09:19 2
402 Cantabs Men IM2 8 Hills Road 09:23 3

123 Chesterton Women Nov 4+ 12:52 166
244 Chesterton Men Nov 1X Connolley 13:52 195

Full results are available via local copy, and likely one day officially.

The mens VIII had a very good row, going over in fine form at 31 all the way, slightly slowed down by having to go wide around Ditton in order to overtake Tabs Greybeards. Steven had decided to drop us down to a Novice crew - leaving out the Mighty IV - so I got a chance to stroke it, which was fun. That left me a bit shagged, which is my excuse for a relatively uninteresting performance in the scull in div 2.

To be continued in legs 2 and 3...

Christmas Head

DSC_9003-post-race-crew-pix_crop

Not to be confused with last year's Christmas Head, where we were cops and robbers. This year the emphasis was on fun; in the spirit of which we entered three crews as Elite mixed, secure in the knowledge that there was unlikely to be another Elite mixed crew out and so one of us must win. And indeed there wasn't. And with three crews there was enough for a category, though since we were all from the same club it sort-of didn't count, though I gather the fastest crew got pots anyway, doubtless some dubious behind-the-scenes skullduggery going on.

The ladies also entered an VIII, and I heroically entered my first proper sculling race (the previous one was time-only); results for all are at cityrc.co.uk/xmas2011-results.pdf.

[This post written well after the event and back-dated, so I may as well say: Happy New Year to all!]
