I think LA is skipping the TDF this year to focus on the hour record

My evidence:

1) LA states that there is clause in his contract w/ The Discovery Channel
that he must the TDF at least once during the two year contract. The exact
year is not specified.
2) The LA faction is rumored to be scoping out locations and even considering
building a custom track.
3) LA is seen riding track Madone.

It makes sense if you think about it: they are two different events. In one
you race for 3-8 hours and only in the last hour at 100%. In the next you
race 100% for an hour *from the gun*.

We've all seen how single-minded LA is... that cat needs one goal and one
only per season.

I'm guessing he'll go for it in late March, May, maybe even as late as June.

Then if he gets the record he'll switch back to endurance training and still
own in July.

Just my speculations, FWIW.

One thing that hasn't been discussed much is the "custom track" concept.
Tracks are designed to serve the purposes of a wide variety of types of
events. You can have a"sprinter's track" or a "massed start track" with
features that are more suited to those respective events. A custom designed
hour track would of course be designed to minimize energy loss. The surface
itself is the most obvious thing. Traction is not a huge factor, so
smoothness, hardness, and levelness would be. The track itself would
probably only need to be 2 meters wide. Presumably you would bank it so that
Lance would be riding perpendicular at points on the track at speed. How
much energy loss do the bends create? On one hand, the compression means you
need to support your upper body more, however, tighter bends provide
acceleration for the bike because the main part of the bike/rider mass is on
a shorter radius than the wheels. The wheels have to speed up to keep up
with the mass that is going the same speed, but on a smaller (semi)
circumference. The main body mass then slows perceptibly on the straights
for the same power output. You would also want to design the track so that
whichever line will be the one Armstrong rides on will not rise, even an
inch, in the transition to the banking for the bends

You can make the track whatever distance you want: what is optimal? What
turn radius is optimal? They are independent factors. You can have a cigar
shaped track or you can have a track with wide turns and short straights. Or
would an elliptical track work best?

I think we all know what you're talking about.....this looks like a job
for Brown Deer. Think about it. Coat of paint, and it's good to go.

Maybe he'll start training after the Grammy's tonight. That combined
with training with O is enough to call it a bad week. Funny how the
Krispy talk got shoved back in this groups face last year. Guess the
lesson was learned.

Maybe, but Dick Lane is more picturesque.

Carl,

I take issue with you on your statement that corners cause acceleration.
Corners slow down riders compared to straightaways in bikes and
everything else.

NASCARs go SLOWER in the turn, not faster. So do planes, trains, and
automobiles.

The reason why turns slow you down is because you are changing your
inertia and it is being lost in extra friction with the track. Going
straight is the most efficient.

So if you want to design the fastest TT track it would be a 40k long
straight piece of wood.

Thanks,

Dude, your identity is blown:

Carl is right. Trace the route of the center of gravity of the bicycle
plus rider as it travels around a velodrome. The CoG drops in the turns.
It also takes a shorter route than the wheels do on the track surface.

When I first saw a power tap profile from a 3K pursuit I rode it took
me a while to figure out where the sawtooth pattern was coming from. I
initially thought it was the wind, but the period was 2X/lap, not one.
Because it was from the turns.

I wish I'd have figured that out years earlier, I'd have been a much
faster pursuit rider if I had.

I thought the subject was "skipping the tour?"

The hour fits perfectly this year...a TT-centric tour, 19km on day one.
A week before the tour he'll break the aero record (at altitude) and
right after the tour he'll try the cannible record (in
manchester)...just to keep people scratching their heads.

If Lance did it this way, the UCI would first certify it, and then
abruptly disallow it and then create yet another regulation pertaining
to velodromes (and definitions thereof).

I personally think Lance is taking it easier so that his wife has less
of a chance in court trying to seek full custody of the kiddos.

Did she tell you she was going to do that? Or do you know someone in the
Texas court system that told you when she filed the case?

Just curious. I know you would never make **** up from your own imagination.

Hell, I'm not even certain that LANCE is taking it easier. The guy hasn't
ridden a full season since before he got cancer. But I don't have any
inside sources.
