Hour Record Rules Revisted/Revised

[memyselfandI]

Yes, I see that now as I read from your blog Jayson Austin hour record analysis. Gives some perspective how low CdA can really be, of course shorter person but still.

 

[TShame]

Rohan says that Wiggins will break his record (saying nothing of Dekker) and that he will attempt it again...in about ten years. UCi has not stated if they will track a sea level record yet, as they have in the past at times. He may also try a nose ring, if Bobridge can break the record for the pursuit tomorrow.

 

[TShame]

Rohan did not publish his wattage file, nor post any of his wind tunnel data. However, he said he did 401 watts over the hour. (As I admitted, my guesstimate was what Voigt would have needed to match Rohan?s speed rather than what Rohan actually did. Right numbers, wrong rider, my bad.)To me, this means his record will not stand. Top time trialists can do 400 watts. Can they ride a track bike on a velodrome effectively? Often not. Can they handle the mental test? Very often not. Can they go to the wind tunnel and get into a proper aero position? Certainly. So, I assume the rider is very aero, else why attempt a record? The bike, the helmet, the aero position are all elements; but it takes a lot of specific training. Obree did more with his mind than his body. For that, he will always rank up there with the best riders to me. He never was in a wind tunnel. He trained on a spinning bike in his basement dungeon. He built one of the best aero bikes in his garage with a bearing he stole from the washing machine. He kicked in his adrenalin when most minds and bodies would give up. In that, he did more than what his body physically could do in training. Everyone should read his autobiography. Someone may even have a go on the new version of Obree's bike.

Just out of interest, where did he say that?

Sarah Storey will attempt the women's hour record on Saturday.

In response tohis Cyclingnews.com quote:
" but we've had no indication as yet whether Dame Sarah be watching the numbers on a head unit during the event or using the data for test runs and post-ride description"
She is not allowed to see any electronic aids on her bike during the atempt by UCI regulations.

I heard Dekker is aiming at 53.8 km for his attempt tomorrow.

So, If Dekker does that, what is that at sea level?
And what is Rohan's distance at the Mexican high altitude?
Maybe something for tomorrow.

 

[TShame]

I plugged in some numbers.
Mind you, I could be way off.

Based on Rohan... his effort would be worth up to 54.79 at altitude.
Sounds high to me, but that adds 2.3 km, which sounds about right.

If Dekker does 53.8, that would translate to about 51.5 at sea level, according to the graphs I used.

Make your predictions before the race. I haven't seen what time the attempt is yet. I'm sure UCI will post it early tomorrow with a countdown clock or something.

I've no idea what Dekker will do as there's no sensible form guide but success will probably change the approach of future attempts I'd suggest. He's been there long enough to know whether he's in with a shot.

I'm more personally interested in the best hour performance attempt by Molly Van Houweling scheduled to take place after Dekker's ride.

When and where will this ride take place?

 

[TShame]

Molly did what, 44.17? Is that about 46.08 at altitude?
The record is at 46.06. Sounds pretty tight (if my estimates are close)
She must be testing near 45 at sea level to make this worthwhile.

Dekker is on at 1:30 est. (I've not heard of Molly's new effort)

I just heard the UCI has cancelled the broadcast for Dekker's hour attempt.

Anyone have a link in Britain or Europe??

Dekker is not on a pro-tour team so his attempt is apparently not important in the eyes of the UCI.

I would love to see his attempt and also that of Molly.

I'm going to try:

mentioned on Dekker's twitter account. Worth a shot.

I got on to the site but I missed the ride - site reported Dekker failed with 52,229.29 m. However officials are double checking the result.

The real official hour thread

Dekker is 52.221

His gear was 58 x 14, which one of his coaches/trainers said was too big before he got on the track. He should have listened and went with 56 maybe.

The announcers on Eurosprt were terrible. They had the time completely wrong. I had my stopwatch going. They couldn't even keep track of the laps for the first five minutes. I believe they were actually watching in a studio and not present at the Mexican track. (It is actually done more times that you would ever imagine.

His was doing a lot of 1:08 kilometers, but sunk nearer 1:10 at one point. They showed a few averages during the race as 52.35, then 52.628, the 52.828 all listing 35k (should have been 20, 25, and 30 k?). then the next marker showed 51.763. Completely amatuer. The cameraman had to look over the shoulder of a track official,

I didn't think he was going to break 52k. Also, Rohan did not believe Dekker would beat his record, though he was very cordial about it, merely saying that it would be Wiggins who will break his record.

52.2 at altitude is about 50 k at sea level. He showed a lot of guts. It was worth a shot. I think if he rode the black line, he would have broken the record, as he generally rode half way between the lines on every turn.

 

[eporesis]

If that distance is correct, he would have beaten Dennis had he held a similar line. He was losing over a meter per lap by needlessly riding so high and then wobbling out of the turns. And the sponges were generously distant from the pole. Moreover, as sponges go, those looked pretty passive. Generally, hit a sponge, it just bounces of the rear disk to no effect but having a sponge minder scurry to reposition it.

 

[TShame]

I don't understand why some are posting about the hour under "road Racing" instead of "Track"?

Anyway, someone posted this unofficial record.

 

[Le breton]

Dekker is 52.221


52.2 at altitude is about 50 k at sea level..

Considering that the pressure raised to the power 2.8 shows an advantage of 7.7% for riding around 1850m rather than 0 m.
while the (physiological) loss of power with altitude would be like 4-5%, I would say that the benefit of riding in Aguascalientes was at most like 1.6 km.

But this type of calculation for a hour long effort tend to overestimate the benefit of altitude (probably because the lab measurements of the effects of altitude are done for much shorter durations)

 

[avanti]

.............. And the sponges were generously distant from the pole. ........................

The sponges are placed level with the top of the blue band at a distance of 20 cm below the pole line.

 

[TShame]

One of the girls at the world's hit the sponges and it really threw the back wheel up. It didn't effect her time as much as I had expected. I thought she would have been relegated because she ran over two then cut on the inside of the third one. Was it the women's 500 time trial?

I also thought the russian sprinter came out of the lane in the last final against Bauge, but it didn't matter since he lost.

 

[eporesis]

I've raced with them close to centered on the blue band, which is not something you'll likely notice until you start. This is how I know that the wet foam ones can be flipped with no ill effect.

Regardless, Voight, Dennis, and Dekker rode like they had the idea that they needed to stay well above the upper edge of the pole. My goal was always to ride the inside of the edge where the track is actually measured. Some riders, like McGee, could spend a lot of time under it.

Different tracks have sightly different transition shapes under the pole line to the cote d'azur, not all make that easy to do. At some tracks if you are well drilled it is possible to ride under the pole in a small valley in the turns - it can be quite fast but it requires good skill when at maximal effort. McGee could do this.

Molly set new masters women 40-44 and USA women's hour record distance of 45.637km.

Congratulations to her. A very fine ride.

 

[TShame]

Good for her. I wonder if she went out for the 46 or just did what she could. I was pretty close with her max being 46 from her 44.17 ride.

One thing no one mentioned before, in the examples of Dekker and to a small extent Rohan and Brandle, is that a good portion of the falling power in the last 15 minutes or so can be attributed to dehydration. Thus, even experienced time trialists who finish strong often find their bodies rebelling. Reminds me of Armstrong's awful time trial in the heat of France, his lips draped in dried spit and down several kilos in weight.
