More fun at Pi yards per rev. :0)

Tuesday night is training night, but the need for discipline is becoming apparent. I’d had a lousy day at work, we’d had heavy rain and hail, and more threatened, and it was gusting about a force 5 or 6. Staying in was an attractive option, but we Cokeurs are made of sterner stuff.

Over the last few weeks, I’ve tried to develop a standard training route, so that I can measure my progress. I ride fast for a timed hour and then check how far I’ve gone. Then I tend to do a few ‘warm down’ miles and include some more interesting/technical sections.

I start at a place called Trent Fields, next to the River Trent, and almost within sight of Trent Bridge Cricket Ground. I ride a couple of miles by the river, then a short section of road, and then I get to the National Water Sports Centre. Then it’s about 4 laps of the main rowing lake. A typical fast hour is somewhere around 12 miles.

Tonight, everything was against me - mental attitude, weather, and mental attitude - and I decided NOT to make a serious attempt on my personal best (12.44 miles in an hour). I set off across the fields at a steady pace. To my left was the skate board/BMX half pipe. For the first time in my life, I saw a skateboarder land a trick!

As I rode past, one of the kids shouted in an off-hand way (if this is possible) “Oh look… it’s the unicycle.”

Read that again: the unicycle. I’m part of the scenery now, worthy of remark - like a beautiful sunset - but not surprising or weird. And no abuse! A few weeks ago, kids on the same half pipe were pouring scorn and abuse on me as I rode past. This is progress of a sort.

(I lied, of course: I am both surprising and weird, but the unicycle now acts as a decoy and the kids don’t notice.)

It was well windy. At the National Water Sports Centre, the wind always blows straight down the lake, except when it blows straight up the lake. I know this - I’ve lived near it for many years. Imagine, then, my surprise to find the wind gusting ACROSS the lake. Here’s me hammering down the side of the lake on a Coker, leaning sideways into the wind at a crazy angle - most uncomfortable.

The strange thing about the Coker, if you ride it hard enough and fast enough on a flat surface, every road leads you to the little Scottish hamlet of Crochnumbness.

One nice thing about training around the lake is that you tend to meet the same people who are running or cycling in the opposite direction. Most of them are friendly; some are encouraging; a few are patronising (“Oh, well done, you’re doing well.” - this from a jogger wobblebottoming around the lake at [walking pace + 10%] while I’m doing 14mph on my third lap on a 36 inch unicycle).

Today, there were three old blokes jogging around the lake. They were clearly serious runners, and were making good time. The second time I met them, they were strung across the road, so I moved to within about 2 inches of the grass at the left of the road, then put out my left arm to indicate that was the way I was going. two of the joggers nodded in acknowledgement and drifted to their left (my right), but the third moved straight into my path, made eye contact and kept running towards me. What was going through his head? In a minute, it would be a Viscount seat!

Having tried the polite method, I tried this: I ducked my head down to break eye contact, and accelerated towards him. I looked up, and there were arms and legs everywhere, and the jogger was sporting the largest pair of eyes I’d ever seen.

I thought I’d pushed it too far, because I wasn’t sure which way he would dive. I guessed correctly, swerved, and as he span in my wake, I shouted, “Well, I did signal!”

To his credit, on the next two laps, he was very friendly.

Another confrontation: the lake is home to numerous Canada geese. I notice that all the goslings tend to be gathered into one place, and a couple of the geese sort of act as nannies, while the rest of the geese relax and think goosey thoughts.

It had been a sunny but cold day, so the warmest place for the goslings was the tarmac road surface. On my first lap, the geese left it to the very last moment to move, despite me clapping my hands and shouting a friendly warning. One cute but foolish gosling ran the wrong way. The Coker went left, the gosling went left; the Coker went right the gosling went right. Had I not been a bunny hugging vegetarian, this would have been an ideal supper opportunity.

As I swerved one last time to miss the desperate gosling, one of the ganders decided it was time to wade in, and suddenly I was confronted with the full wings out and hissing beak routine. I can picture the scene tonight in the Duck and Grouse public bar as he tells the tale of how he faced down a 40 mile an hour penny farthing all on his own.

I had not set out for a ‘personal best time’, but as I got nearer to the end of the hour, I got my head down a bit and upped the pace. At the hour, I’d done 11.44 miles - a mile (or 8%) less than my personal best, but given the strong wind, not too bad. Most satisfying of all was that I’d put in a reasonable time (3rd best ever) and ended with lots left in reserve.

In my warm down lap, I usually ride over the tops of the grassy banks at the side of the lake, as well as following some of the rough tracks by the river, and around the other lakes. The grassy banks are great, because they offer a reasonably predictable surface (mown grass) and a range of options. Some of the hills are quite steep, and there are summits, saddles, and all manner of challenging topographical features. I like the challenge of what I’d call ‘tactical hill climbing’ - picking the best route to get to the top, rather than just slogging my way up.

One part of my favourite route takes me to a top, then along a ridge, down into a bit of a saddle, then up onto a sort of grassy dome. The top of the dome is only a few yards across, and the sides are pretty steep. My plan was to ride to the top of the dome, make a sharp 90 degree turn to the left and drop down the short but steep slope onto an easy grassy run off. The alternative was to go straight on down a slope to steep for me to ride on the Coker, with no run off; or to turn right and do a long steep descent, wasting all my gravity karma.

So, I rode to the top of the dome and did a sharp left as the pedal went down… then a huge gust of wind caught the wheel and blew it straight again, as if I were perched on a massive weather vane. So I turned left with the next pedal stroke, and it happened again! Eek! One more pedal stroke and I was 3.14 yards closer to the near vertical drop than I had intended. My next attempt was desperate and I turned just more than 90 degrees, and you’ve guessed it - I weathervaned the other way! This was a new and challenging aspect of Cokering.

By the end of the ride, I’d done 19.56 miles in 1:54.02 (riding time, not elapsed time) and, bizarrely, my maximum speed was showing as 23mph.

This was clearly wrong, as at the end of the fast section, as always, it was showing 14mph. This freak reading has happened once before (I think it was 20 mph last time) but I can’t work out why. I know it’s nothing to do with idling, because (a) I always place the magnet carefully when I set up a computer, so it isn’t in position when I idle on my strong side; and (b) I didn’t idle.

Wow! another great write up Mike. I was going to put down a list of the best quotes from it, but as I read on i could see there would be too much. If only I could write like that in my english GCSEs. After much deliberation, I have narrowed it down to one:

Ok, two:

Oh btw, the dodgy speed could happen if you go over a bumpy bit of ground or fall off, causing the reed in the sensor to wobble quickly and give false readings.

Great story! I can’t believe you didn’t close the deal on that gosling, however. :smiley:

Mike-

Thanks for yet another entertaining write-up. You should be starting a collection by now. I found the title especially clever this time. When will you bring back the Roland Hope School of Unicycling?

is it just me or does everyone suddenly feel the urge to buy the Big One?

…a few mental calculations later…

so… are you affiliated with unicycle.com in any way? do you get paid a certain commission for every coker sold? < chin stroking >:)

Mike: although I have only cokered a hundred feet or so, your nice narratives have really given me the magnitude of this vehicle.

I’m sorry to those who like the extreme videos, but I would love to see the Documentary of Mike’s Rides around this Coker Paradise. Is there no videographer around that can do this?

hi
just a question about your posting:
as a kid I was sent to school in England just to try
to learn the language.
I remember that everybody was confused because they were
told to turn to the metric system and this was so new and strange!
the teacher in geography was heavily relying on my experience on the matter (I was both fluent in the metric system and a real expert
with maps).
now I am reading R.S.U and I am confused:
how come brits still use the imperial measures (after so many years)…
I know people from the other side of the pond still stick to old customs :slight_smile: but do you really
think in miles or are you just polite to the vast majority of readers?

I am interested by that
( when uk turns towards the Euro!:D)

Nope, we really do think in miles. On our road signs we have distances in miles, our speed limits are in miles etc. etc.

Collectively, the English are rather silly about the whole thing. I can’t comment on the Welsh, Scottis or Northern Irish.

We started to go metric in the late 1960s. I remember being told about metric measurements etc. when I was at infants’ school (aged about 7). We decimalised our coinage around the same time. We have parents and grandparents who were born AFTER the metric system becan to be taught in our schools. But nevertheless, we cling to a strange mix of old and new.

Air temperature: on hot days, we measure in Fahrenheit. 90 degrees in the shade sounds so much hotter than 32 degrees.

On cold days we use Centrigrade (Celsius) because minus 3 sounds really cold, compared to 26 degrees.

Road distance, and speed we measure in miles or miles per hour, even though it would sound “better” in metric. (Doing a metric ‘ton’ on a 125cc scooter is achievable!)

Small distances we measure in feet and inches. Carpets come off a 13 foot roll, which is now called a 4 metre roll. The looms are unchanged, so the carpet is identical! But many shops sell “12 feet off the 4 metre roll”, mixing their measurements willy nilly.

Weights are usually in pounds, ounces and, for big units, stones or hundredweight. I aways translate into pounds in this forum because I’m not sure if US readers know about stones.

Even very small distances are measured in ‘imperial’, even though 15 centimetres might sound better than 6 inches in some contexts.

And as for the money: we have a huge slice of our population ready to die in the ditches defending the Pound. Yet I can remember when the Pound was a piece of green paper worth 20 shillings or 240 pence. Now it’s a small coin worth 100 new pence. It’s a totally different thing, but with the same name.

We’re just weird.

things may become difficult for metric people …
I mean I can “smell” what a 20", 24" wheel is
but when unicycle.uk says “legs as short as 28"”
I am sudenly wondering how much is that?
aren’t my legs too short?

since you all seem to like exercise I suggest that, when necessary,
you also convert measures to something 80% of the planet can “feel”

thanks

In Germany, some things are still measured using imperial, wheels are one example but also plumbing connections and pipes, socket drivers here are still 1/2" or 3/8"

What really did surprise me though, our Nissan Micra has 13/16" wheel nuts.

Here’s a link to a few pictures of the hilly bits Mike writes about (the white water course here is really cool):

White water cokering? Wow! :slight_smile:

Yeah? I think a ‘century’ might be closer to what Mike meant. In either case, quotation marks are called for, as a metric ton is 1000 kg, and by a century in most cases 100 years is meant (but it can ‘officially’ mean the number 100 too). Or so I’m told.

Klaas Bil

Metric Systems in the UK

Almost all engineering and industry has converted to metric.

(with the exception of pipe sizes which have been converted to milimetres and left at the same size they were and are still called 3/4’’ pipes…)

All engineering designs are mm which causes considerable confusion when working with Americans (and to them also from what we can tell of NASA’s ill fated Mars probe).

Some while back one of the councils put up public information signs to tourist attractions with distances in metres, several locals pulled them down in discust and were taken to court. The court told the council that all public signage must be in yards and so they lost (to much public embarasment as the case was all over the front pages for a while).

The Fool

PS, What does goose taste like? I have never tried it.

  • Goes to get coker to ride up and down the river towpath for a while to find out…

Paddington gave Klaas Bil a hard stare…

‘Ton’ is exactly what I meant.

A ‘ton’ is a speed of 100 mph. It has been since the 1950s, or even earlier. It’s motorbike slang which has passed into more general use. Motorcyclists who rode on the highway at 100mph used to be called ‘ton up boys’. These days, the double ton (200mph) is achievable on one or two road bikes, and the ton (100mph) is no longer really a ‘magic figure’.

By extension, a ‘metric ton’ would be a speed of 100 kmh. The expression is used jocularly in the scooter press. A typical 125cc motor scooter is able to do something like 100kmh, but nothing like 100 mph.

I meant ‘metric ton’ in this sense.

A ‘metric ton’ in the sense of 1000kg is a ‘tonne’. An imperial ton is 2,240 pounds or 1016.05 kg, so as a unit of weight, they are as near as dammit identical.

(there is also an imperial ‘short ton’ which is 2,000 pounds, or 907.19kg, but this measurement is seldom used.)

A ‘century’ would be used in any context where a total of 100 units was accumulated. A century always refers to a total or quantity, rather than a rate or speed. The traditional example is 100 runs in cricket. Also, reaching the age of 100 is called a century, and some people would refer to riding 100 miles as ‘a century’.

Actually, this is what Americans mean by ‘ton’.

Re: Re: More fun at Pi yards per rev. :0)

Well, there you go - two nations divided by a common language.:wink: I understand Americans call the other sort of ‘ton’ a ‘Moving Traffic Violation’.:smiley:

You use F? Blimey, I know you said you were old, but, well…

He’s right though folks. It seems to me that any Brit born before
sometime in the mid 1960’s will use Fahrenheit at least some of the
time. My parents (born in the early 1950’s) use it all of the time.
Having been born in 1973 I never use it, although I am practised at
converting one to the other in my head.

Yeah, but a mile is so much easier to visualise than a km. I think the
reason we cling to imperial distance measurements is that inches, feet
and yards are nice, easy units to visualise. A yard is about a pace for
man of average height, making it a very practical measurement. But a
metre - well, how do you visualise one ten millionth of the distance
from equator to pole?

Ditto. I don’t think they do. (Note for US readers, a stone is 14
pounds).

“6 inches” is 3 syllables, “15 centimetres” is 6. The difference in
time it takes to speak the measurements might be another reason that
imperial remains so popular.

I would love to have been around in those days, it seems to make so much
sense.

Frankly I’d be quite happy to join the Euro, except that writing and
testing conversion routines, arranging for them to be run simultaneously
at over a hundred sites and dealing with any issues and queries arising
from it would mean a massive increase to my workload.

Why not just think of a meter as about a pace for a man of average height?
