Re: Re:

GPS is roughly as useful as a random number generator - can the host broadcaster not just do a proper time check on a notable point, they have cameras with both groups

ABSOLUTAMENTE!

Doesn't GPS basically measure how long it will take from group behind to reach the point where group ahead is at a moment - IF going on steady speed.

Thus everytime peloton hits an uphill, the gps is frantically deducting seconds and contra-effect on peloton getting to downhill...

The distance increases/decreases if the groups are at different slopes, but the time gap should remain the same if the group behind goes same pace as the group in front did when it was at the same place. But there obviously is some coding needed to translate the x,y position into ridden distance and thus comparable to the previous group. And if the gps is taken from motos, then their place may affect it too. But I admit that it should be better.

Aight, I think its over for Chaves now.

Chaves could lose 5+ minutes if Quickstep decide to sit up at some point.

Re:

Can't trust GPS enough to say that - but if they really have a 2 min gap then the peloton just need to keep it for another 55kms or so, and then the terrain becomes not very favourable for the sprinter teams to even keep trying

 

[Eyeballs Out]

Think there is a tricky little climb coming up which is probably going to be the final nail for the Chaves group

Nah, he has most of MS there to ride when needed

 

[ruamruam]

If this doesn't come down quickly Quickstep will give up and save their energy for another day

Im sure GPS measures distances based on gps position. when second group arrives at the same point as first group, the time difference is measured. It should be accurate no matter what the terrain, or speeds.

The software they use is much more complicated than that.

For instance it also takes into consideration current speed, as well as speed at each given point in the race, for each rider, which allows the software to take terrain into consideration.

In other words, if the group in front loses 5 % speed in a given sector (going uphill), the next group will be expected to also lose 5 % speed in the same sector, which is then added to the projected time gap.

Usually, when we get these GPS errors, it is a connectivity issue, not because the software does not work.

The problem for chaves is that as soon as QS thinks they can't make the catch the gap will grow much much bigger. If the stage finishes now it would already be bad, but it's nothing compared to what he might end up losing after 100 more kilometers

 

[glassmoon]

QS will soon realize it's not possible to bring EV back and that will be the end for Chavito's hopes...

 

[DFA123]

Have to say, it's a pretty nice (and nasty) stage design. 240km and 4,000m of climbing the day after a rest day, starting with a 1,000m climb. A good chance someone significant was going to find it a struggle.

 

[RedheadDane]

Viviani throwing in the towel?

 

[Jagartrott]

Game over I think.
The longest stage raced so hard, right after a rest day - that's got to cause some damage.

 

[Waterloo Sunrise]

Utterly breathtaking views

QS have now given it up, Chaves riding himself, game over.

MS need to now take the day off and rest up to support Yates - any more effort today is throwing good money after bad

Chavito pulling himself!!!

Re:

And they just pulled up - now it's all Mitchelton

 

[Red Rick]

What Mitchelton can do now is give up, or try and lose their team strength by wasting as much energy as possible for no gain at all

 

[Valv.Piti]

Thats at least 5 minutes. Probably closer to 10. Bad flashbacks from Belkin screwing Valverde over!

Re:

Indeed. If Chaves is the great team player I'm told, he'll surely be one of the first to realise they need to now save their energy to support Yates.

How else is Bauke Mollema supposed to beat Valverde in GC?

What to Expect:
Big breakaway and peloton just inside the time limit. Unless a favourite bonks on the first climb of the day.

Prescient.

They guys in the second group has no way to support Yates anyway, so they may as well keep riding.

Stuff can still happen, someone can crash in the front group and change the dynamics

 

[bigcog]

Chavez has a sore throat/pollen issue

I don't know why they feel the need to make it more complicated. That would be perfectly accurate enough.

I have honestly never forgiven Mollema and Belkin after that day, I remember I was so incredibly pissed and had some very harsh arguments with DT on another forum.
