It's not that bad. Wind resistance, or aerodynamic drag, varies with the square of speed. The
power required to overcome it, however, varies with the cube of speed.

Thanks.

How much difference does the effort or speed make? I would've thought that you'd use more or
less the same energy riding 10 miles in an hour as you would by doing 10 miles in half an
hour, given that in the former although you're at a gentler pace you're in the saddle for
twice as long.

At 20mph most of the effort you do is against the wind, so you will do more work riding at 20mph
for half an hour as at 10mph for an hour.

Good reasoning which I hadn't thought of, but then again, at 10 mph I'm in the (less) wind for
twice as long?

Pete (not at all into aerodynamics but just thinking logically - or illogically as it'll probably
turn out)

But resistance is proportional (roughly speaking) to the square of the speed, so half the time, but
4 times the effort.

Right answer, but not quite the right reason. As said on other posts in this thread, resistance
(wind) is proportial to the square of the speed, but the power needed to overcome that resistance
goes up as the cube of the speed.

So you go twice as fast = 2*2*2 = 8 times the effort, but for only half as long, so that's 4 times
the effort expended in total.

At about a quid ago for 1l of soya milk versus about 35p for 1l of cow's milk, there's not really
much incentive to switch..

Tescos and Morissons do it for 69p/65p respectively. The 65p Tesco value one isn't worth it, being
diluted and without the calcium of the ordinary.

Ah, I must start shopping in Tesco's more often. Tesco's usually seem to have better range of
organic food than most supermarkets, on a vaguely related note.

Morissons? Never heard of them. We obviously don't get 'em round here.. :-)

Nobody's forcing you not to eat milk. And there's nothing wrong with having some soya and some
cow's milk.

I know, but it's just one of those things that once you (well, me) start thinking about it, seems
to make more sense than not, which was the point the original poster was making. So while
weaning(!) myself off cheese might be difficult, I might as well just try to cut out all other
forms of milk if I can..

I suppose it's like driving: people do it because they just haven't thought about the alternatives,
but once you start thinking..

The thing is, I don't think I could easily give up milk entirely. While I don't consume much milk,
I like cheese too much (well, pizza in particular ;-), and having to scrutinise the ingredients of
everything to check no milk has snuck in would be just too much hassle (even most sunflower
margarines have various milk products in them).

The Pure brand has no milk products in their sunflower or soya margarines. It seems to be available
at most supermarkets these days.

For a wide range of organic produce you need Waitrose. The fresh produce also lasts longer than it
takes to get home, which is a plus when compared to most supermarkets.

I have found that borrowing the idea of the Atkins diet has helped. I have cut down on
carbohydrates and occasionally cut them out altogether for a couple of days at a time. I haven't
followed the diet strictly but when carbs are reduced or eliminated, I do manage to shift some of
the weight. Up to half a stone in a week.

My weakness is treating myself for succeeding with a small loss in having a few jars of lager at
the weekend and then eating sandwiches afterwards as I feel so hungry. This is in part due to the
restricted carb diet.

Try to find a balance between the "no carbs" and "carbs" days. The point is that carbohydrates that
are not burnt will be converted into fat. Carbs that you don't digest and/or do burn will therefore
never be converted into fat. That's why you lose weight quite easily.

<gentle ribbing> I always find it quite amusing how unaware we all are [1] of quite how diverse the
UK really is. We ain't got no Waitroses in this country! In fact, I think even in England they're

[1] ObCycling: I had a really fascinating conversation recently with a prominent English cycling
activist where he learned a heck of a lot about just how different the
political/legal/organisational makeup is in Scotland, and (partly to my surprise as I thought I
knew most of the gist of how things work darn sarf) I learned quite a lot that I didn't
previously know about English local - and regional - government as well!

We certainly don't have them here (Yorkshire). I've only ever seen them in London/Home Counties.

For me it conjures up images of the morning after one Chris Mason's 21st birthday, involving Chris
Mason, a can of Castlemaine and a box of cornflakes... No relation of Simon. I hope.

Hehe ;-) I was just teasing, Guy. Sorry if you took offence! I just thought it quite funny at the
idea of having to trudge 400 miles to find my nearest Waitrose.. 🙂

Ah, that would be telling.. 🙂

But it just goes to show, the way things work in Scotland is so different from the rest of the UK,
that pretty much we almost are a foreign country - and the worst bit is, that even most Scots don't
realise the extent of the differences(!), because (until recently) TV/radio news largely reported
government actions affecting England only (or E&W) as if they applied across the whole UK, and
unless you looked hard, you were none the wiser..
