tunnabora test on the trainerroad

Garmin Cadence Sensor
The rain was blowing horizontal by the time I'd decided to go for a bike ride this morning. It gave me an excuse to further shake down the winter season bike.

I was out yesterday in comparative sunshine on my blue bike, although I did notice a slight cooling of the air. Today it was time to take out the semi-winterised orange one, which I'd set up a few days ago, but only just added a cadence sensor so that I can measure things properly. At the time my early prep seemed needlessly pessimistic, but what a difference a few days make.

I use that ANT+ protocol for my bike metrics. It's a bit like a very short distance wireless personal area network and I decided to standardise on it about a couple of years ago.

Interestingly, just adding the cadence sensor to the bike means I can also use it as a sort of power meter when it is connected to a PC or Mac. Power meters for bikes are generally quite expensive, but there's a software version that simulates the effect and can be used for a workout.

I'm using something called Trainerroad for this purpose - which is surprisingly good and simple to set up. It uses ANT+ to link the cadence sensor, speedo and a heart rate monitor to the PC and then takes readings. It doesn't even need a readout on the bike, although I do use my Garmin for that.

I can then play various trainerroad turbo trainer tests whilst it sets goals and monitors performance like a regular trainer would do. Its doesn't control the turbo (or rollers) but uses their calculated resistance (virtual power) to set the targets for the workout.

I'm only working through the so-called Intermediate scripts at the moment, which (no doubt for ego reasons) is basically the simplest set of workouts, designed to last over six elapsed weeks. The first time you use it, there's a test to analyse for the maximum personal output sustainable over an hour (Functional Threshold Power), using two 8 minute tests. This then calibrates the other scripts so that they are do-able. If I'm honest, I found the original FTP200 setting too high and had to wind it down a bit.

I've now worked out how to set up the individual session to run at the bottom of the PC screen, with a TV show playing above it (I'm watching Mad Men Series 2 at the moment). At some point I might take some pictures of the set-up, but for now, here's an example of one the outputs from a one hour ride.
tunnabora test
To begin with I'm finding it difficult to track to the targeted output levels, although I suppose I'll get better with a bit more practice (& fitness).

golden spiralling - but not out of control

Untitled
Before the picture of the sunflower scrolls out of the main pages on the blog, I thought I'd mention that it's a 34.

I don't do it with most plants, but sunflowers require that special extra moment to (a) estimate and sometimes (b) count the number of petals. Not if they are a complete field full of flowers, you understand, but if they are singular.

Some people are surprised that flowers have set numbers of petals when they grow, but I think I'm 'amazed'. I know it is all about Fibonacci series and phi and golden means, but for some reason the sunflower is the perfect type of flower to check that nature is still working properly.

The right number of petals for flowers are (1), 2, 3, 5, 8, 13, 21, 34, 55, 89 and not really any other numbers (I know there's a few mutations, and so-called 'doubles' like on lilies, but let's stick with the main ones). The arithmetic is simply that the two previous numbers add up to the next available combination.

So my sunflower planted by the birds is a 34, and Pat's Michaelmas daisies are also 34s.
rose
My picture of the complicated rose above is probably an 89, but it is a bit difficult to count the petals. I suppose that's the attraction of sunflowers for the purpose. They are easy to count.
pineapple
The same thing happens with the spirally bit in the middle of a sunflower. The clockwise and the anticlockwise number of spirals are also in a similar ratio. It'll be something like 34 one way and 55 the other way.

Even pineapple bumps do it. Count the clockwise spirals and then the anti-clockwise ones. It'll be something like 13 one way and 21 the other.

There. I've managed to rationalise my flower petal counting. Now, back to the spreadsheets.

drive my car to penny lane

penny_lane A bit of a helter skelter day tripper visit to Liverpool today, including a stop in a road with a famous name.

Altogether now, it was a magical mystery tour, during which I had to drive my car, following someone along a long and winding road.

I should have known better, but my ticket to ride didn't give me time to let it be. I suppose I was here, there and everywhere, before I had to follow the sun to get back.

a bat, an indifferent hedgehog and a sunflower

Our sunflower planted by the birds
The bat that flitters around our garden at sunset is quite unphased if I'm outdoors and will usually swoop for a quick look before going on with its hunting for insects.

The midnight rambling hedgehog is similarly happy to continue about its fairly slow speed rummaging for earthworms. I have this theory about townie hedgehogs having a good turn of speed so that they can avoid cars, whilst country hedgehogs are more likely to roll up in balls which might not always be in their best interest.

The one in our garden treats me with indifference. And yes, I do know that song by Stackridge. And the one by the Incredible String Band.

Today's feature, though, is one of the sunflowers which have been donated by the birds. I spotted it a while ago, when it could have been mistaken for a fast growing weed. Fortunately I decided it was a plant in the right place, so it survived and today receives the iPhone photographic treatment.

pickin' me a bouquet of dogwood flowers

Candy 1
I took yesterday's bike picture with the camera set to 'automatic' and the flash-gun popped up. I couldn't help notice how it made the bike look quite shiny.

No such luck with these pictures of the bike's pedals. Most people seem to use either the original flat pedals that come with bikes, or get those road clipless pedals. For some reason I've always used the mountain bike type clips even with road bikes.

I'm sure there must be some down-side to using them on a road-bike, but I'm not sure that it makes all that much difference.

It also means that I can have the same pedal types everywhere and also that they have little flat pedal surfaces for cycling in other shoes.
Candy 3
The ones I use are called Candy and I notice I still have what would now be a collector's edition of an old type on one bike. The black ones are the long surviving originals, with special plastic inserts for different colour combinations - see my imaginative choice of grey.

The blue and the gold pedals supposedly signify different qualities, although I'd say the blue ones are by far the highest mileage.

And speaking of mileage, I see that I have now passed my 3,000 mile cycling target this year, which I think I decided would constitute a Silver Wagon Wheel award. My original target set back in January was 1,600 miles, so I think I'm doing quite well.

And I'll now see if I can achieve 4,000 miles by the end of the year to achieve a Gold Wagon Wheel. Construction and consumption of the wagon wheel (Silver at this stage) will follow in another post.

steel frame and disk brakes being prepped for the upcoming season

winter prep already
This is going to sound sort of daft, what with it being sunny outside at the moment, but I thought I'd better check a different bike in preparation for the upcoming seasonal changes.

After my recent musing about the fixie, I've decided I'll go back to a retro steel frame and some wider tyres for the winter. I took it out for a preview spin to check that the various components were working. I know it's early, but I'd rather be adjusting things in the warm than later on when everything gets a bit more painful.

Truth be told, everything was in good nick, except that I discovered after the trip that the brakes were very slightly 'on' the whole time.

I'd initially put this down to just being on a heavier bike but after I'd finished I thought I'd just spin the wheels to see how they compared with my road bike.

Hmm. Quite a difference. The road bike's wheels will spin for quite a long time (many revolutions), whereas the steel bike was only 2-3 revolutions at most.

I initially wondered about oil and bearings and things like that, but then loosened the brakes just in case they were the culprits. Sure enough, there was a marked improvement. This winter steel bike has disk brakes, so I did that thing with the thin piece of card to get the clearances right and then retightened everything.

I think the next trip will be easier.

Next is to remember where I've put all the little lights and clip on mudguards.

a surfeit of scrumpy

arch duke
We'd agreed to meet in one of those railway arch type wine bars near one of the main-line train stations.

It's a well-known London venue, but was surprisingly quiet when we arrived.

We'd both taken the precaution to travel by public transport, so that some modest imbibing would be possible.

I should have heard the buzzer making that 'Brrp' noise and seen the big red cross in the air.

But I didn't.

"They do a good cider here," said my friend.

"I'll give it a go," I replied.

It looked innocent enough and fairly clear. Not an obvious rough scrumpy candidate although the apples had that tart taste.

"It's only six-and-a-half-percent," said my friend.

I should have remembered that I am not very cider-proof.

We had a great afternoon.

Although I did decide to make it an early night.

And this morning's 6 a.m. start was surprisingly difficult.

Tonight it will be comfort food.

Beans on toast.

And no cider.

all of your adapter are belong to us

all-of-your-adapter-are-belong-to-us
I see the new iPhone has been announced and that it can show even more icons for Apps purchased from the App Store on the new bigger screen.

The faster chip required to refresh the larger screen and the increased pixels require more battery, so they've shaved the circuit boards to pack the phone with ever more lithium ion polymer.

I also noticed that there's a revised connector - named Lightning, which is to go with the already available Thunderbolt high speed connector.

It's a clever commercial move to design a new connector.

None of the existing stuff will fit it, except with an expensive and fairly ugly adapter which costs about £25.

I guess next iPad will also move to the new connector, so we'll all eventually have another collection of defunct power blocks and adapters.

* excuse the poor artwork above. I've been using PS CS6 and not quite figured out a few of the changes.

iPhone 5 unboxification


Katzenstok technology threatens to upset the launch of the newest Apple iPhone via Puppetshed.
Thunderbolt and Lightning, very very frightening me.

sun appears again


Kudos to our fellow blogger Daniel (@danielh_g) for getting the lead in this advert for the Sun newspaper. I saw it on telly last night in the middle of a drama show and felt the need to rewind it and watch again. Very entertaining.

As is the way with T.V. ads, there appear to be several versions and the one I've featured above is the full 1:30.

The sun seems to get featured in these 'morph between scenes' type adverts, as witnessed by the one below about the sun coming out - and featuring the fastest beachside quickdraw of a mayo that I've ever seen.

And of course, there's always the ones where there 'Ain't no sunshine' too - as witnessed in the famous walkthrough scene in the movie Notting Hill.
