an indication that the lead athletes think a finish time of 2:01:40 is possible.) Moreover, all three lead athletes seem committed to running a world record, which means they need to Nike Roshe Run Dámské work together at the prescribed pace, for as long as possible. But one can never know what is the mind of a professional runner when his blood is up. Kipsang could make a break at 10 miles and blow the world record attempt to pieces. It might be the Nike Air Vapormax Damen best way for him to win the race. It’s not just the speed of the pacers, but how they run together, that could make the Nike Air Odyssey Dámské difference. One of Breaking2’s signature innovations was the tight six-man triangle shape that shielded Kipchoge and his competitors. This shape had been tested in a wind tunnel and using computational flow dynamics software, and was Nike Air Max 90 Herren proven to offer the most protection of any formation to a runner nestled just behind it. After Breaking2, I wrote that this one innovation could prove an extraordinary benefit to future record-legal marathons. Because of a strange custom with “gold www.annieleibo.cz label” races that means only three pacers are allowed for each group, Berlin will not be able to recreate the Monza triangle exactly. But the organizers of Berlin have learned some lessons from Breaking2. After the pre-race technical meeting in Berlin, I was told by one athlete manager that the three lead pacers would run in a line, with the middle runner slightly Nike Air Pegasus 83 Damen Herren forward from the others—in other words, in a triangle. Another lesson from Breaking2, where sports drinks were consumed regularly, Kipchoge has asked the organizers of Berlin to arrange more stations where he can take on a carbohydrate-rich Nike Air Max 90 Herren Blau drink, in an effort to slow the depletion of his energy stores. In fact, all three contenders will be using the same mixture—made by a young Swedish company, Maurten—that Kipchoge drank in Monza.In any event, Adidas will be championing Nike Air Max Thea Dámské its own marquee shoe: the adizero Sub2, which was specifically designed to “take athletes below the two-hour barrier.” The Sub2s weigh around 150 grams—about 100 grams lighter than Adidas’ previous best racing flat, which should translate into a 1 percent increase in running economy. Kipsang wore what Adidas claimed were the world’s only pair of Sub2s when he won Nike Air Presto Dámské Tokyo earlier this year, in 2:03:58, and will wear another pair tomorrow. Whichever athlete wins tomorrow, their shoe sponsor will not keep quiet about it. Pacing Themselves (And Other Strategies) The pacing tactics in the race will Nike Air Max 2015 Damen also be intriguing. Most fast times are set when the pace is steady: an even, fast pace is the best way to set a world record. Most marathons with deep, strong fields tend to be inefficiently paced, because the pace often spikes and troughs as the www.wimatherm.de studs test each other’s fitness. Berlin is a well-organized race, and it has recruited three excellent pacemakers—Gideon Kipketer, Geoffrey Ronoh, and Sammy Kitwara—to guide its lead athletes at least as far as 20 miles. (The pacemakers have been asked to reach halfway in 60 minutes and 45 seconds, which is faster than any marathon in history, would have been Nike Air Max 90 Dámské černé unthinkable even a year ago—that is, before Breaking2
