WINDYYYYY! how do you convert this workout?

7.8

6.4

9.1

7.76 troll

If your serious, the effort without a headwind would be around 4:45 pace

Convert it? Why bother? Just say it was windy in your running journal or whatever and write down the real times.

I hope you are joking. If not, you ran around a track which means, the wind helped you one way and hindered you the other. So, in reality, it should have no effect at all.

I hope you're joking. You've never run when it was very windy before?

I have run when it was windy before on a track. Yeah, it sucked running into the wind and made me slower. But with the wind at my back it made me run faster, therefore, making no effect on the time.

Right on brother. That's why running on a hilly course never slows me down as long as it ends at the same elevation it begins. The ups and downs exactly equal out.

wind definitely slows you down... somebody with a good answer will post

and no, hills do not equal out if you end at the same elevation... try running chicago. note your time. then run pikes peak. you'll then understand. Jacka$$

Jack Daniels talks about this briefly in his book. An 18 mph tailwind reduces VO2 demand by 10% while an 18 mph headwind increases by over 20%. It's further complicated when you're running across the wind. I read another book that went into more detail on this and on hill running, but I can't remember which one. Hills are the same way though, you never get back as much from the downhills as you lose from the up. I'm sure somebody else here has read the same book and will be able to post the physiological reasons.

Let's say you're running along at 12mph (5:00 mile pace). On a day with no wind, you will still feel 12 mph of wind resistance. It's kind of like craching a car into a tree....the tree wasn't moving, but you still feel the impact because you were moving. Best analogy I can come up with real quick.

Now, on a windy day, you're traveling at 12 mph with 30 mph gusts against you. This feels more like a 42 mph wind would feel if you were just stationary. This would be like hitting another car head-on.

Now suppose you're running with the wind. If you are traveling at 12 mph and the wind is also at 12 mph, you will feel almost no air movement around you, like running on a treadmill. Or, in our car scenario, it would be like the tree chasing you down the high way but never catching you.

If you are running 12 mph with a 30mph, you will only feel 18 mph of that because your speed is negating the rest. This would be like a car, in the same lane of traffic, bumping you from behind because they are going faster than you. Definitely not as traumatic as the head-on collision.

So, in gusts of 30 mph wind, going into it feels like 42mph "hitting" you, with it feels like 18mph "pushing" you. Obviously, these are not equal.

that's some good stuff. also just think of riding a bike into the wind and against it. huge difference. all the world records and other really fast times have been run with almost no wind

Here's a link to a calculator that give wind adjustments to pace as one of its functions.

http://runworks.com/calculator.html

It suggests that 5:30 pace with no wind is roughly equivalent to 5:00 pace with a 20 mph tailwind and 6:45 pace with a 20 mph headwind. Taking a straight average would give a 20 second/mile slowdown with the wind in your face half the time and at your back the other half. In reality you're not always going directly into or against the wind so that's a reasonable upper bound. On a day like that, you just train by perceived exertion and pace falls where it may, especially if the wind is gusty. The clock doesn't mean much.

For what it's worth and based on some background in sailing, it's my experience that people almost universally overestimate wind velocity and sailors lie about it.
