Jesus Green is surprisingly nice at this time of year; not energy-sappingly chilly, and it's pleasant to discover that I can in fact swim a hundred yards at a time without stopping. Twelve lengths, so a bit over a kilometre; four each breast-stroke, back-stroke and crawl. Fast crawl took me just over three minutes but left me heart-pounding and distinctly dizzy; the other strokes seemed to take about 4.5, though I think I always managed under five minutes — looking on wikipedia, this is almost exactly four times as slow as the world record holder, which is probably the best spin I can put on my unreasonable sluggishness. I was a bit surprised to find that I had trouble walking in a straight line as I got out of the pool at the end of the swim; chlorinated ears?

It's clear that I hang around at the ends of the pool for as long as I think I can get away with, so Jesus Green's having a quarter as many ends as Parkside is an advantage.

Sadly I managed to miss [ profile] numberland; I'll try again next week.

The exercise has left me too tired to spend the evening sitting creatively in front of a hot iPhoto to prepare the full shiny photo-post that I promised [ profile] taimatsu, but look what I saw at the weekend:

At least, I think kittens are proverbially slow and graceless swimmers.

Managed a kilometre this evening - 40 lengths of Parkside, changing stroke every six lengths to ward off some of the boredom. It took just under ninety minutes; I found that two consecutive lengths of brisk front crawl (where 'brisk' means 40 seconds for the 25 metres) raised my heart rate to 180, one minute's rest got it down to 120 and another minute got it to 100. For comparison it goes up to about 150 on the stair-climbing machine and stays there, and tended not to get even that high on the treadmill (when the treadmill was working).

What would be wonderful is to try swimming with someone who not only can swim but can tell me what I'm doing wrong; I find I can't get any speed at all from my legs, it takes over two minutes for me to do a length holding a float in both arms and getting my propulsion from swimming furiously.

Weird weather this evening; low-contrast clouds and haze enough to cloud one side of Parker's Piece as seen from the other, the sun setting as a visible disc rather than an actinic blare. Rather reminiscent of Bangkok.

After about a month's hiatus, I managed to get myself back to the gym today after work, and back into what had become my standard pattern - twenty minutes on the stepping machine, ten minutes on the rowing machine since it's so boring a movement that I can stand it no longer, a few dozen sit-ups, and a while spent waving fairly light weights around (traditional up-to-shoulder, ears-to-above-head, and, with straight arms, in the three possible permutations waist-to-in-front-of-eyes, in-front-of-eyes to parallel-with-shoulders, and parallel-with-shoulders to waist).

I've no idea if these are sensible exercises to do if my goal is to be able to hold onto hand-holds on the climbing wall, but I'm sure some of my readers know better.

Then to the pub, to counteract this mild virtue with a hot Thai curry; met up with [ profile] uisgebeatha, [ profile] cartesiandaemon and others, and followed them to Emmanuel for a ceilidh. Apparently there are ceilidhs weekly in Cambridge during term-time, which I would have loved to have known earlier, and which [ profile] atreic would happily have told me several years ago had only I thought to ask; this was the last one of them this term, next is 7th October.

In the afternoon I wandered out of work for an hour and cycled up to Comlab for the Intel Research open day; gives some idea of what was presented. The posters had the normal problem of targetting an audience already sure that all its problems would be solved by efficient attachment of InGaAlAs ring oscillators to an epitaxial GaAs base, or adaptive tuning of packet characterisation trees, or the ability to express network specifications in a formal logic denser with extra fonts and multi-directional arrows even than the usual; but I hadn't realised how much I missed talking to enthusiastic grad students, and the multi-disciplinary overload that that kind of cluster of presentations provides.
