Well, I've done my part in trying to assure good conditions for this year's race! I bought a set of 105mm rain wheels and double sealed bearings for my wife to ward off wet conditions. What should I buy to prevent headwinds?

A special made "golf ball" aerodynamic skin suit that cuts through the wind. All to have the event be a 10-20mph breeze of a tailwind that your suit virtually negates. Do it for the people!

What kind of bearings are they? I could probably use a set like that just in case.

bearings are Twincam ILQ-X mr2

I got them because our training trail runs thru farmland and in the spring the dust coming off the fields from the tilling and planting gets everywhere, especially when there is a light misting of moisture on the trail. I got tired of cleaning 2 sets of bearings 2 or 3 times every spring. We'll see next year if they help any.

the road paving sounds like is shaping up for NSIM'15!

super idea... I could make one myself (sort of) by gluing 1/2 ping pong balls to a suit! I'd have to make sure it didn't look too much like a Dalek.

Just looking at the entry fees this year, even with attendance down they have already collected $136,000... plus what ever other entries come in. Im curious if the entry fees were not so high, how much that could boost their attendance. I know a few people who will likely not make it due to the cost.

Here is again, with data from 2012 added. Wish I had 2013.

As we all know... participation continues to drop and I don't know if there is very much "skating wise" the NSIM leadership can do about it. Maybe something on the side could be tied in and promoted which could tap into our general demographic (fun, athletic, young at heart). Maybe some entertainment. Maybe a beer tent outside to cater to the rec crowd (the big participation numbers). Maybe associated lodging could offer NSIM special rates that would encourage folks to come instead of stay home. A rate drop might not have to be huge... but enough to say "hey, we WANT you to come, so we aren't going to over-charge you"

I am teaching a seminar in the Twin Cities that Saturday, and won't be making the race. Next year, though...

Browsing through the FAQ, I see this line:

Quote:
If you have raced the race before, the computer will place you electronically. If this is your first race we will go by your estimation of your finish time.
Has anyone ever been automatically placed by the computer? This will be my 6th year and it seems like I have always manually selected my wave.

I'm guessing that Bart will go on a solo breakaway for the final 26.2 miles

Might be a challenge if the current prediction of a 9mph head wind bears out.

Grand Forks was crazy this year. A 12mph tail wind meant that the first three across the line were solo breakaways with minutes of separation between them and between #3 and the "lead" pack.

The headwinds will probably discourage the pack from an organized chase, so I think it favors a small breakaway staying away. I don't know if Bart will be able to get away solo early. I'm betting a small group of about 4 or 5 guys (including Bart and Joey) will get away a few miles into the race. The chase pack will go hard for a while, but will lose momentum and the lead group will get out of site.

I'm curious to see how the break works together once they are out of site. There's a chance that as they get closer to the highway, they will start playing the cat and mouse game and the chase could catch (like it did a few years ago), but I kind of doubt it.

Anyway, just my prediction. We'll see how close it plays out to that.

Not that I'm watching, but recent forecasts have trended to a tailwind. Currently I see 4mph from the north at 9am shifting to NNE at 10am.

yippee! the forecast of 50% chance of light rain has been replaced by SUNSHINE!! It must have been the purchase of boot covers that chased away the clouds.

The forecast I have says to expect 6 to 7 mph breeze from NW... which means drafting just a bit left of center of the person in front.

It's funny guys that no one mentioned Jan Blokhujsen because the scenario is very clear.
It seems the plan is as follows:

1) 1 mile after the start Bart and Jan (who dont know who Jan is - look into wiki) probably will push to the limit and broke the elite group - maybe one, two, three skaters will be able to survive next 3-5 miles (it depends if they will cooperate with B&J or not)
2) after mile 7 - Bart and Jan will be probably alone

Assuming weak side wind and 125mm frames they will be able to maintain ~47km/h - it allows to go below 54mins.

Bart already did the same with Severin Widmer (he was outpaced ~10 mins before finish) last year in Berlin. I think Jan has no significant experience in inline but he is stronger than Bart on ice and Stronger than widmer on inlines. Depending on the road situation Jan will try to do the same or even will pass the finish with Bart. On 110 wheels they can broke the record but by seconds and wind they will play important role.

sxevegan: I don't think Joey is endurance skater and if he starts he may be one of the skaters who survive 7 miles. Afaik Joey will not start there - if he will, he for sure help Bart as he knows perfectly he is not endurace type of skater.

Spencer.Berry: Bart many times mentioned (in Berlin in afterrace interviews) that he hoped that Severin Widmer survive at least 40 mins cause he was not sure about surviving alone.

I think it really depends on what Joey has been doing for training. He has won many marathons in the past with times approaching 1hr5min. Hard to say what he will be able to do.

No matter who is up front, if they don't have kind of tail wind there is really no chance to break the record. If you assume that Chad had a 10mph tail wind, then his speed relative to the air was only 17mph. Wind resistance goes as the square of the velocity so if you have no tail wind you will have 250% more resistance to maintain 27mph. (27^2)/(17^2) = 2.52 = 252%. This assumes that all other things are equal. Big wheels help but I don't think they help in that much.

The calculator on this page is fun to play with.

It seems the plan is as follows:

1) 1 mile after the start Bart and Jan (who dont know who Jan is - look into wiki) probably will push to the limit and broke the elite group - maybe one, two, three skaters will be able to survive next 3-5 miles (it depends if they will cooperate with B&J or not)
2) after mile 7 - Bart and Jan will be probably alone

Assuming weak side wind and 125mm frames they will be able to maintain ~47km/h - it allows to go below 54mins.

Bart already did the same with Severin Widmer (he was outpaced ~10 mins before finish) last year in Berlin. I think Jan has no significant experience in inline but he is stronger than Bart on ice and Stronger than widmer on inlines. Depending on the road situation Jan will try to do the same or even will pass the finish with Bart. On 110 wheels they can broke the record but by seconds and wind they will play important role.

sxevegan: I don't think Joey is endurance skater and if he starts he may be one of the skaters who survive 7 miles. Afaik Joey will not start there - if he will, he for sure help Bart as he knows perfectly he is not endurace type of skater.

Spencer.Berry: Bart many times mentioned (in Berlin in afterrace interviews) that he hoped that Severin Widmer survive at least 40 mins cause he was not sure about surviving alone.
Looks like Joey indeed can be an endurance skater. Bummer the record didnt fall. Kind of make me wonder about Harry Vogels claim that the record was BS.
