A good time for 10km TT?

If you work on intensity and increase your 20-30min threshold (~lactate
threshold)

The intensity that you can maintain for 20-30 min is well above lactate
threshold, even if you mistakenly use the latter term to mean maximal
lactate steady state/critical power.

then your 2hr sustainable power will also improve.

Only if the increase in your 20 min power is due to an increase in
metabolic fitness, and not due to an increase in anaerobic capacity.

One ride
a week or so before your 100km race that matches the amount of energy
(like W-hrs) that you will expend in the race, will be enough
"endurance" training.

Enough for what? To be able "fake it" through race, maybe...but
certainly not enough for a young person to be the best that they can
possibly be.

Welcome back chief scientific officer. I hope you enjoyed your sabbatical
in Vulcan and managed to find a suitable mate during the mating season.

So what effect do such long rides have in increasing ability to tolerate
or recover from intensity during races as I (empirically only) think there
is (for me) an improvement ? (note I don't subscribe to the other myth
about riding below some given intensity during such long rides and mix
several fairly long climbs in on most of my long rides.)

And before the next Vulcan mating season starts, may I also enquire
whether you think a Powertap SL is worth the difference in price over a
pro ?

This is nonsense. There is no minimal speed at which a reduction in
aerodynamic drag isn't helpful (even if only to a very small degree).
In fact, in terms of absolute time saved, slower riders stand to gain
the most from the use of aerodynamic equipment

And yet below about 25 mph averages the total decrease in TT times
would be offset by the rider simply sitting up too often which of
course he would do at lower speeds where it takes so much time to
complete the TT.

In ANY case, a person should be setting records for his area without
Aero stuff before he starts using it.

Why?

Buying into the "aero" crap before you can ride is about as smart as
purchasing a Ferrari in California where the speed limit is 70 mph.

I thought power tapping was thouroughly covered last year...

Mostly in theory in rbr.

If I had to guess, I would say "an increase in the mitochondrial
content/respiratory capacity of normally hard-to-recruit type II
fibers". Note, though, that long rides aren't the only way of induced
such an adaptation (although they may be the most pleasant way).

I don't have any personal experience with either. The only difference,
though, is the hub, and I haven't seen anything to suggest that the SL
hub is significantly more reliable than the one you get with a Pro
system. (The bearing in the SL hub may last longer, however.)

Non-sequitor.

So now you're the arbiter of other's purchasing decisions?

Comments like yours remind me of the joke I heard on NPR on Saturday:
the president's press secretary claimed that the push for a
constitutional amendment banning gay marriage was "a human right's
issue". The comedian wise-cracked "yeah, like Prohibition was a happy
hour issue".

That's right. And it's also good psychologically and makes my bike look
pretty. So give it all to me, because you lot don't need it.

Hi All,

Now that I know my time trial course is flat, I'd like to see how the
local riders stack up to others around the world.

The best guys in our club 10km TT are all just under 14 minutes. There
are a bunch under 14:30. They all have full-on TT bikes. How good are
these guys? What USCF cat-level is that, sort of?

I have a best of 15:45 on a regular bike. How good is that?

I don't have much else to compare because our road races are all
rather
hilly I'm off the back (at 100kg+) and thus never get a clear picture
of where I stand. At least not any clearer than off-the-back
somewhere!

Thanks,

Joseph

The head units are the same. The difference is mostly(*) that the SL hub
weighs 160g less. It costs about $300 more, so that's $2/g.

* the SL has sealed bearings on both sides. The Pro has a sealed bearing
on the LHS but a POS cone on the RHS. You can replace it when it wears out
with a Dura-Ace part.
