Quoted message said:Hi guys, I am using my MTB to get fit and lose a few
Kilo's. I go for rides that say average around 60km's. I
use smooth roads, so no off road stuff. I have semi
slick tyres.
My question is, whats an average speed that I should
achieve to get maximum benifit. This is the average
speed that you check at the end of the ride on the
computer. At present I am getting around 24.5 kmh
average speed. Seems slow compared to the " Tour De
France Riders who average 42kmh, but then again, they
are elite athletes, on road bikes.
I say this is pretty respectable for a mountain bike, am
I right ?
24.5kmh for a 60k ride.
I actually just read a book about using exercise to become
fit / lose fat.

At $11, I think it's worth a peek. And the author is a fan
of mountain biking.
Anyway, based both on my experience and on this book, I
would say that your average speed doesn't matter one whit.
I'm going to paraphrase several chapters of the book:
You do not have the body of a TdF rider. Nor do you have the
body of a slug. You have your own body, and you can't use
others' performance to guage your own accomplishments. A
more athletic person will need a more intense workout to be
exercising aerobically; a less athletic person will need a
gentler workout.
There are two forms of exercise: aerobic and anaerobic.
According to the book, you can tell you're exercising
aerobically when you can speak a few words at a time while
exercising. You should not be able to recite the pledge of
the allegiance, but you should be able to get a few words
out without having to gasp in between. When you exercise
aerobically, you're burning the most calories.
Also according to the book, if you find it difficult to gasp
out a word or two, you've moved into the realm of anaerobic
exercise. The thing about anaerobic exercise is that, while
it's not the most efficient way to burn calories
immediately, your body will burn more calories than usual
for the next 48 hours as it repairs the muscles you've used.
If your thighs are burning, you are exercising
anaerobically.
His recommendation was to use a mix of both (actually, more
than that, but that's as much as I want to type about), but
with more of the aerobic stuff, because it's much more
efficient at burning calories than the anaerobic stuff is.
Anyway, just some ideas. Any mistakes are in my
interpretation, not the author's intent. Any feedback
is welcome.
