I am riding my bike for fittness, and to lose some weight.
My question is, when I go for a bike ride on a hot day, I come back with my
clothes drenched in sweat, however now that its a little cooler, I am coming
back after the same level of riding, but with bugger all sweat.
Am I still acheiving the same results even though I am not sweating as much

As you get fitter, and your body gets more efficient, you WILL sweat
less for the same amount of effort.

The indicator of whether a workout is doing you good (fitness wise) is
supposed to be how long you spend above a certain percentage of your
maximum heart rate. That percentage figure will vary depending on the
expert, but I think it's somewhere around the 75% mark.

What I found, as far as sweating goes, was that as I got fitter I
started sweating earlier, but sweated less overall.

Make sure, though, that the reason you're not sweating as much isn't
because you're dehydrated.

A confounding factor is that as you ride faster, the sweat evaporates
faster due to increased airflow, so I don't think perceived sweating is
a good workrate measure. If you're serious about riding for fitness, buy
a heart rate monitor (HRM) - it doesn't have to be a fancy-shmancy one
with zones, PC interface, etc., just something that tells you your
current heart rate. If it doesn't come with a little booklet that gives
you a clue about what HR to train at, go to your local library or search
the Web for articles.

Other methods (not as reliable) of measuring workrate include:
- which gear you're in on a known stretch of road (this is only a
relative measure, and the "norm" will change as you get stronger and
lighter)
- perceived workrate, i.e. how hard you think you're going, which is
accurate most of the time, but as my HRM tells me, not *all* the time
(sometimes 150 feels like hard work, sometimes 165 feels cruisey).

If you can afford ~$150, I'd suggest you get an HRM.

P.S. Peter is right, your body gets better at dissipating heat as you
get fitter. On your first few rides, you may have come back red-faced,
but on later rides over the same route and in the same conditions, your
skin colour would be much more normal.

Your body doesn't need to sweat as much at cooler temperatures. I als
ride to an from work. I find that in the morning I'm not sweating muc
at all. If it's a warm/hot day on the ride home, I can barely get m
jersey off it's so wet. So in my experience, the weather plays a hug
part in how much you sweat (and hence how much you need to drink)

Perspiration rate/amount can be affected by several physiological and
environmental factors. In addition, there is no feasible means to
measure perspiration rate/amount quantitatively.

A meaningful way to monitor your fitness is perhaps watching your
average speed against your HR. Even this has to be done over large
sample size, as the speed can be greatly affected by wind, heat,
humidity, state of the bike, the state of body etc. So, I'm afraid that
monitoring fitness is going to require some tools. Something that allows
you track your performance and gives you numbers to crunch.

I got caught out badly in this year's Alpine Classic

virtually all my longer rides (100k+) are in the morning and rarely
approach midday. The alpine classic had me finishing after 9:16 hours at
3 in the afternoon and I realised there was a huge flaw in all my
training and that was not getting used to riding at the hottest part of
the day. Really suffered on buffalo

As an aside to this...are you riding in a t-shirt? They certainly keep
you sweatier (more sweaty?) than perhaps some of the cycling or
running tops that I have tried.

Rob

Someone with a stronger biology/physiology background may be able to verify
this, but I seem to recall that as you get fitter you actually sweat more.

The key is that, yes you do sweat earlier. Your body perspires freely while
you are exercising, it cools you down as it dries, and you arrive feeling
cooler, not red, dripping and done in. Because you are sweating more, a fit
person will need to drink as much or more than an unfit person. So suck on
that bidon.
