2:04:11 in 69 degree weather, with dew point of 59. world record-quality performance?

69 at 6:30 in the morning isn't the same as running at noon. 59 degree dew Pont is great.

69/59 aint terrible, sure. but berlin was temp of 54-55, dew point of 46-47. i aint run your speed, but ive run hard and long in both sets of conditions. they feel vastly different.

Lol, is this a serious post? How drunk/high are you right now? "Pont" lol

The announcers on eurosports said their was a cooling breeze, and one said he put on a jacket. That was within the last 30 minutes. At that point Tola looked great. At the end Tola looked very tired so the conditions changed quickly. But he also ran a two-minute PR.

You neither understand running or science.

69 degrees for a marathon is not great.

And you are an expert at both?

I find a Pint to be much more enjoyable than a Pont.

Dew point anywhere near 60 is a bear to run a marathon & especially if you're trying to run fast!

He's as much an expert at running as you're going to find.

Malmo should be coaching at a high level.

Lol OK I'll trust the guy who can't spell "point", doesn't know to use "nor" and has no clue what a physchometric chart is.

When the race starts a half hour before sunrise it is.

Huh??? That's fully 20 degrees warmer than optimal temp of 49.

Mercy me, I took a look at the title and though it said 2:04.11 800, I was sure it was a troll thread

No

I don't think you're going to get this, I don't know if you are even capable of understanding what should be junior high science, but I'll try.

Temperature is not a fungible metric. 69 degrees here is not the same as 69 degrees there, or over there. That seemingly precise number isn't so precise at all. When the weather service reports temperature it is an "in the shade" measurement. 69 in the shade is quite different than 69 in the yard with the sun directly overhead, which is different than 69 on a concrete sidewalk, and even more different than 69 on an asphalt street. You already know this. The ground level ambient temperature on a sunny day is going to be much higher than that 69 degrees that the weather service is reporting. If is is cloudy then 69 degrees doesn't feel bad -- even at noon.

The Sun's altitude makes a huge difference in the ground level ambient temperature vs the reported temperature. At sunrise the Sun's radiant energy hasn't yet had time to amplify at ground level, so 69 is 69, just as the weather service told you. But at noon the ambient temperatures on a sunny day will probably be 20 degrees higher.

Boston Marathon used to start at noon. The NYC Marathon used to start at 10:30. This went on for decades until the slow-learning Einstein's finally realized that the runners were screwed on sunny days, so they eventually caught on and moved their starting times earlier. Now it's not unusual to see 8 am starting times. Berlin is 9am. Dubai is 6:30, a half hour before sunrise.

Running a marathon at 6:30 in Dubai, temperature 69, dew point 59 is not a problem at all, as was clearly demonstrated. Understand yet?

Remember the Golden League 5000 at Doha has been won in 12:50 when it was 90 degrees on the track. How come? 90 at 9pm isn't the same as 90 at noon...that's how.

And we can add that getting a course record is not really a great way to prove it was too hot. People blew up, right. But they started at better than world record pace. That was bound to happen.

Still a great performance by Tamirat Tola.

I already splained on the discussion thread that he held his hands open. Among other things, including simple acclimation, that allowed him to stay cool without sweating. As long as you can do that, there is no harm in high temperature. It's when blood must be diverted to the skin that you tank.

What I say about Mo Farah's cleanass bald head, and Lagat too, really works. Their shorter distances are more energy intensive and require faster cooling. Marathon doesn't require as fast cooling, but for a much longer time, so you can't get away with having a bad cooling rate like many do in 5000 or 10000, unless the temperature is "perfect" around 50 degrees.

Reliance on cool temperature is a cheap excuse for not training to race conditions. But does it work in reverse? Why should it? Training in hot weather can raise blood volume as an adaptation to excessive sweating, but sweating doesn't work in a marathon. The ability to stay cool without sweating is what matters, and that doesn't translate to any advantage in cooler weather. It can even be a disadvantage requiring the wearing of gloves and hats to cover the body's natural radiators.

Bekele is way too endomorphic to perform well in hot weather marathons.
