Brad: “I’m not a weather man, but if you have really low pressure, under 1,000 [grams per cubic metre], you will travel a lot further on the day – anything up to one kilometre for the same power. The weather forecast for the first week in June is abnormally low pressure for London for that time of year, which is fantastic.”

Me: "grams/cubic metre" is density not pressure. Pressure is measured on Pascals (N/m^3). Brad, I hope you and your team use the correct units when setting your ride schedule.
Why do you pretend to be a scientist and then fail to point out that his comment is still relevant due to the fact that a compressible fluid (gas to you) changes its density with the pressure applied to it? Credit where credit is due.
 
Observations that may not be of interest to many :) :
1. Brad's time at 4000m. was approx. 4:29 I think;
2. Brad covered the first 16 km. in 17:36.279, about 22
seconds faster than the 10 mile (1609m) road TT he did
in May in his failed bid for Mr. Dowsett's other record;
3.Brad's narrow arm/hand position while improving
aerodynamics, made it a little more difficult to hold
the black line (as everyone who has experimented
with this sort of thing knows :eek: ).

There was no need to point out that one goes faster with lower pressure as Brad already said so. I pointed out his incorrect units. Some coaches use different units to predict performance and inputting the wrong units can give false results. By the way I am a professional aerodynamics engineer - my name reflects one of the many aircraft I've worked on.

Has Bradley Wiggins really set a new record for the hour? It seems to me that his bike is very little different from Chris Boardman's. It's certainly not like anything you would normally see even in a time trial.

The history of the UCI hour record has been of various rules and categories. Between 1940 and the 1990s, there were six simultaneous and different categories of hour record.

Heck, even Neil Stephens held a UCI world hour record at one time (1987) under the professionals / indoor track / below 600m altitude category.

So yes, he's set a new record based on the regulations in force at the time of the attempt. Is it the absolute furthest distance set under UCI regulations at the time of the ride? No.

The incorrect units belong to the editor/author of the cycling news piece, that's why they are in square brackets

Molly Van Houweling said she broke her own record hour in a 'training ride' in LA
(not sure if she meant the 44.173 sea level).
She added that she has sponsors for a July 3 attempt in Agua. Mexico.
Cranking 44.1 led to 45.67 at altitude.

And 45.67 / 44.1 = 103.8%, bang in the middle of the predicted range of improvement in speed of going to altitude:

So, maybe a 51.5 at sea level effort, if I read the chart right.( I didn't do the math as I'm lazy.)

The hour record, is a road event. All hour record holders, are Roadie. As far as Wiggins goes, same thing.
That's more because the training required to be an effective road racer suits the effort for the hour more than the training for track events does. There's nothing stopping an Omnium, Points race or Pursuit specialist from doing the training and having a shot though.

Actually, if you have a look at how Cam Meyer used to win points races it might not be a bad idea, because there would be some carry over.
 
Martin Toft Madsen (DEN) set a new Danish hour record yesterday with his impressive 52.114 km. It was never advertised as a world record attempt but rather an attempt to beat Ole Ritter's old Danish record from the 70's. It happened during Copenhagen's six days event (at Ballerup Arena). Martin Toft says he'd like to target the world record too in the future.
 
Just read that a Dutch cyclist Dion Beukeboom is going for an attempt next year. Would be a huge surprise to me if he even came close. But nice to see people trying!
