Rite. Yep forgot about the technology. I was going on estimates. Spose its like cars, some go further on a gallon of petrol. Harder though to burn off those Kals.

But thinking about it, surely the Polar just measures HR (not power) it can't 'know' your heart stroke volume nor your muscular efficiency. Therefore it just uses HR as a number and not as a measure of respiration, I'm no physio etc but I should think two different HRs could achieve the kal burn? Praps some of the experts can take this on?

Interesting this, we should have a competition as to who can do the most mileage on a toasted teacake.

1700 is what the polar said and who am I to argue. told you my HR was wy low. Usually for a 6hr/100mile ride I only burn around 2200-2800 depending on how hard I go.

I'm not sure if thats a good thing or not? For me low cal burning is bad but on the other side a low hr is good? ro have I got it all wrong?

Gat's, I'm curious as to what your max HR is? I'm usually so gee'd up before a ride that I'm already over 120 before I've stepped out the door :oops: A 120 average for a hard 4 hour ride sounds really low to me, although I know that everyone is different.

Pah....All this headwind stuff .I spent 4 hrs on a dance floor last night :? .Max cal burn and the toty put my pulse rate through the roof :twisted:

HR isn't a great way of measuring calories burned. Because as you get fitter (lower avg HR for the same number of km) you still burn the same number of calories for that ride, all other things like speed, weight, aerodynamics and wind being equal.

Calories burned relates to the amount of work you've done. Currently, the most portable way of calculating this is using a power meter and factoring in your body's efficiency for converting food -> energy (something like 22-23%).

There wasn't any rain but the wind was demoralizing. Managed 54 miles riding the beast and knackered once home.

This sounds a bit familiiar. I'd memtally prepared myself for the rain but didn't realise it was going to be so windy untill I was about ot venture forth. Didn't abandon early but then I was never going to go all that far before opening time.

I went out (the ice had thawed) expecting rain (it poured all night) in my dayglo Altura jacket on my Winter Bike (naturally) and did 21 miles at my usual tempo. There was wind but it always seemed to be with me (insane, I know, since I was doing a circuit) and it stayed dry all the way round.

I felt pretty good on the bike: high cadence, eating up the hills, heart lungs and legs all doing fine.

Then I got home and discovered I was soaked in sweat (the Altura keeps it in, whatever they claim), frozen to the core and in the kind of muscular distress that you might feel after tumbling down a long stone staircase.

Whatever planet my head was on when I was out on the ride, clearly it wasn't the one my body was struggling across the surface of. Don't you just love mind over matter?

I've no idea what my max hr is. My resting is somewhere in he 49-52 region. Weird before I get on the bike having been up and wandering round the hourse getting ready my HR is about 65.

Is a low HR good then? I always thought it was a bad thnig. On the commute this morning I was 140av hr for 16miles. did it in just over an hours inlcuding a stop to change a puncture.

We should do that comp about the tea cake though cos I always do my century+ rides without breakfast so know that I can go at least 120miles on a banana and half a bottle of water.

No tht's not insane at all, because for every action there is an equal & opposite reaction. Every time I go out the wind is against me even tho the curcuit is a circle!

I can do this as well, but I don't because it is a completely pointless exercise! By the time you complete the ride your glycogen stores will be depleted and you will be gaining no training effect. In fact doing such a ride is likely to reduce your performance and have a detrimental effect on your immune system leaving you open to viral infections.

The low heart rate you experience on these long rides is an effect of this. You really aren't doing yourself any good at all and furthermore you actually inhibiting your body's metabolism and ability to expend calories. ( Which you seem unhealthily obsessed with )

I can ride at my best early in the morning, before breakfast but with a big intake of liquid, ( tea then water). This will do me for my usual training ride (35klm) but if I want to do a long ride . 60 klm, then I need to stoke up!

Although I agree you definitly train your own body, so starve - work - food certainly builds up body fat, (in preparation for starve - work) so a regular intake AND output of energy is required to balance the whole machine.

BTW there is a train of thought that says you can live off protein (body fat) rather than carbos, but that is a bit extreeme. It DOES work (I know) but for short periods.

OK, OK i put the teacake thing in for a laugh, certainly don't want to be the cause of you olympic contenders coming down with flu in the road race.
We have a Saturday run round here called the 'teacake' run which for the chain gang means 50 miles of torture through the Peak - an all for a t' teacake at the cafe!!

Now I'll get on back to work.

Haven't been out since before Christmas. Went down with pnuemonia on Christmas eve and am still not 100% yet. It's the first Christmas where I've lost weight, nearly 6 kg! Can't wait to get both lungs back so I can try out my Christmas haul, new lights and gloves.

Got back from the Revolution and into bed at 1:30am, alarm goes off at 8:20am for the club run. Lumpy ride, very windy and tons of rubbish on the lanes - my bike had half of Shropshire on it when I got back. Nearly bonked for the first time in ages too.

You have to question your sanity sometimes

I've got to back Grimpeur's words, having been there/done that/never got any faster for several years. I ride much better if I eat a bowl of porridge before I go out. Fat burns in a carbohydrate flame and all that. I guarantee that when I started having a proper breakfast each day, I didn't put on any weight because of it.

Faster riding = more calories burned/hour, but also more calories burned/km because power required doesn't scale linearly with speed. And you will get fitter and enjoy it more, which is arguably more important for a cyclist than their weight.
