As you increase intensity, in general, the total amount of energy you
burn increases, but the absolute amount of fat increases *to a point*
then stops increasing. So the percentage energy from fat decreases at
higher intensity, but you still burn just as much (roughly, yes Tam, I
know ....) fat per hour.

So yes, you burn fat effectively ni z2/E2/whatever higher zone you
define, but you burn more sugar and glycogen as well.

I've only just started racing. I rode a C grade
crit a few weeks ago and won that (with a breakaway).
Since then I've ridden two B grade crits and have
finished with the bunch! Last week I had a go at
another breakaway. Me and another rider stayed
away for about 4 laps but got caught. Tried again
later but other riders sat up. So, I can stay with
the bunch but no results at B grade (yet!). I feel
like I'm getting more competitive though. My sprint,
however, is useless.

That's quite a low VO2max for a B grade rider - it doesn't necessarily
mean much, but it's interesting that you can keep up with that sort of
number. Most B grade riders around here are in the 60's or so, as far
as I'm aware. VO2max is only an indicator, after all

Couple of things to note: it's B grade Vets and the crits are
*flat*. I reckon I'll be struggling as soon as the road points
up. B-grade averages around 38 to 39kph for the crits.

I'll be finding out about the hills soon enough. I've put my
name up for a TdU companion vets race in Adelaide next month:

Not that familiar with the area but there'll be a couple of
hills I'm sure! It's also a handicap race so it'll be flat
out all the way.

I'm hurting already.

What kind of doc gives a VO2 max test based on that?!

Ok.

That's an eastern combine (Victoria) C grade open average on
most flat courses.

Yeah, there's a hill or three on that course!

> I'm hurting already.

You're in WA, hrm... not a lot of long hills to train on, but there are
a lot
of predictable headwinds, which are pretty similar!

Tam

It is reasonably common for a respiratory physician to ask for a full exercise study in patients with unexplained exertional shortness of breath that cannot be diagnosed with simpler means. Most patients don't achieve a true VO2max, as they are not sufficiently motivated, but some do. You won't get an OBLA; being less useful for medical purposes, lactate is not measured.

I suppose the challenge is getting sent to the respiratory physician in
the first place. The GP ordered blood tests and said I was fine and sent
me away. I self diagnosed and did well and the problem went away... not
that I would generally recommend self-diagnosis...

Nice effort, but you really need a companion to share the work. Too
many heroes in B-grade who are happy to drag the bunch back to you.

Is there a race report that I missed?

I did have one guy with me but we mutually gave up after
a while. There was a strong headwind down the back straight.

No race report I'm afraid!

How's the racing at Bunbury?

Sparse. I went on a training ride with the SWCC guys through the hills
at Australind on Saturday. Saturday's ride is hard on the flat and
harder up the hills. If I can keep up with these guys I'll be riding
vets A grade before long...
