Thomas Dekker misses out on UCI Hour record in Mexico

Dutch cyclist gets close to distance Rohan Dennis set earlier this month, but falls just short

Thomas Dekker of the Netherlands failed by just one lap or so in his attempt to beat the UCI Hour record in Aquascalientes, Mexico today.

At the end of his 60-minute ride, his distance was given as 52.250 kilometres, but there was confusion throughout his ride as to the exact distance he had covered. It was later given as 52.221 kilometres.

Although his final distance took some time to be officially confirmed, what was clear, however, is that the rider, without a team after being let go by Garmin Sharp at the end of last seaosn, had failed to beat Rohan Dennis's record of 52.491 kilometres, set in Switzerland earlier this month.

While the attempt - the first to be undertaken at altitude since interest in the Hour was revived last year - was screened live on British Eurosport, the host broadcasters in Mexico provided few clues as to his progress.

That wasn’t helped by a clock in the bottom right-hand corner of the screen that turned out to be running slowly, ticking over 50 seconds in what people commenting on Twitter quickly worked out was in fact 60.

An occasional graphic showing his average speed at the same distance covered as Dennis and Brandle, and at around the halfway point he was just slightly down on the current record holder.

There was also doubt over whether the flipboard-style lap counter at trackside was accurate.

Perhaps mindful of the criticism on Twitter regarding the absence of information, TV producers resorted to camera shots over the shoulder of a woman who was writing, by hand, the progress as each lap passed.

But with Dekker turning over a larger gear than Dennis, who set his record at the same Velodrome Suisse where Jens Voigt last September became the first man to break it after the UCI’s rule change last year, it seemed doubtful that he could beat it as the clock  ticked down.

Attention now turns to the Lee Valley VeloPark in London, where on Saturday afternoon Dame Sarah Storey will become the first rider to attempt the woman’s Hour record since that rule change last year.

The attempt will be streamed live on the UCI’s YouTube channel as Storey looks to overhaul the existing record of 46.065km set 12 years ago by Leontien Zijlaard-van Moorsel of the Netherlands.

Assuming the Aquascalientes velodrome is at about 6,000 feet, then the air pressure would be about 200HPa lower. That's about 80% of sea level pressure. The reduction in drag will be offset by a similar decrease in oxygen. Even with lots of (higher) altitude training that's still a big ask to knock out a 52Km hour. Temperature becomes a bit critical as well; I wonder how hot it was? I see that Chris Boardman suggests that Sir Brad tries at sea level and 28 degrees C.

For what it is worth, I think I remember seeing one of the graphics say 28 and 31degrees.

As for those whinging about altitude advantage, Merckx set his time in Mexico and no one seems to be complaining about that, as did Moser.

Maybe he could have another go tomorrow. That's what Obree did. Bit cheeky going at altitude so oddly happy he didn't break the record

I doubt he'll gain a contract from that. As a previous doper, teams are very wary of giving a chance to them. Plus he seemingly turned down contracts last year to focus solely on the record attempt.

I wonder how much distance altitude is worth.
Any sports scientists worked it out?

Alex Simmons takes you through the air resistance gains and performance losses in his excellent blog. Maybe worth about 1.6-1.7km for Dekker from my reading, compared with Velodrome Suisse.

That's still a superlative effort, I'd be surprised if he didn't gain a new decent contract from that.

Maybe he'll still get a new contract out of making the attempt at the hour record.
