does anyone know how good it is?
it's crap i just tried it. It only adjusted my 5k from 5,000 ft to 10,000 to 13 seconds, which is ridiculous. If someone can find the NCAA conversion, it's much better.
From the list of Altitude adjustments used by the NCAA:
3,124ft (Billings,MT) 3k-6.97 sec, 5k-12.29 sec, 10k-30.54 sec
4,009ft (Portales, NM) 3k- 10.08 sec, 5k 17.63 sec, 10k - 43.83
6,007 ft (C Springs, CO) 3k- 18.97 sec, 5k- 32.76 sec, 10k - 81.63 sec
7,703 ft. (Gunnison, CO) 3k- 28.54 sec, 5k- 48.98 sec, 10k-122.21 sec
Subtract all of these adjustments from the time that is run at altitude to get the "equivalent" mark.
where by chance did you get that? This is very helpful
If someone used my data to come up with that altitude calculator, they did something wrong. Our original data were used to help determine the adjustments that the NCAA uses. If I were to give you an adjustment on the data I have, I make the following for an altitude of 2000m (6562 feet) -- 5-min race = 4.2 sec, 10-min race = 15 seconds, 20-min race = 40.8 seconds, 30-min race = 72 seconds. At 2250 meters altitude (7382 feet -- also similar to Mexico City Olympics where the winner in 10k was just over 29:00 and the 5k just over 14:00), I would give a 30-minute race 1:48, a 20-min race 54 seconds and a 10-min race 21 seconds. The NCAA did not want to use a formula that could be applied to every altitude (rather they wanted to identify specific cities) and specific distances (rather than durations of a race, which is more accurate). Anyway interpolate as you will, that's what everyone else does. But that samll difference between 5000 feet and 10,000 feet of altitude is not accurate.
just out of curiosity how much approximatately does altitude affect sub-maximal efforts. I mean what is a 60 min 10 mile run at 8500ft or 5000ft? Or what is 7 minute miles at sea level worth at those alitudes. I used that calculator, but i guess its wrong, and I won\'t be racing at altitude just training and I am curious about sub max effort. thanks so much
here is what i put in from the runworks calculator. I just don't find this conversion to be remotely close.
sea level 15:41.5 3:08.3 5:03.0
1000 ft (305 m) 15:44.6 3:08.9 5:04.0
2000 ft (610 m) 15:47.8 3:09.6 5:05.1
3000 ft (914 m) 15:50.9 3:10.2 5:06.1
4000 ft (1219 m) 15:54.1 3:10.8 5:07.1
5000 ft (1524 m) 15:57.3 3:11.5 5:08.1
6000 ft (1829 m) 16:00.4 3:12.1 5:09.1
7000 ft (2134 m) 16:03.6 3:12.7 5:10.1
8000 ft (2438 m) 16:06.7 3:13.3 5:11.2
9000 ft (2743 m) 16:09.9 3:14.0 5:12.2
10000 ft (3048 m) 16:13.1 3:14.6 5:13.2
Note I ran this 5k at 7000ft and the following conversion for sea level is way off. going from 5000 ft to 7000 ft is the same as going from sea level to 5000ft, meaning that the air is that much thinner beginning at 7000ft.
Figure about 10-15 seconds per mile slower at 5000 feet of altitude (compared to SL), and closer to 20 seconds per mile at 7500 altitude. These differences apply if fairly acclimatized to altitude. It will be a little more per mile if a newcomer to AL. SO, longer intervals, threshold and marathon pace runs will all be affected about the same per mile. ON the other hand, reps (200s, 300s, 400s) shuld be the same as yur usual rep pace at sea level, but you may have to take longer recoveries between the reps
Does anyone have the OFFICAL NCAA or USATF track times conversions? I live at altitude and am wondering if I can use CU's track meets to qualify for faster sea level meets such as the Cardinal Invite.
jtupper or anyone,
where do i find the current altitude conversion standards for the various distance events?
thank you --.
i was wondering if anyone has an expanded calculator for other events. i need to get a cconversion for the 1000 meters.

Thanks for this, jtupper! I was actually just thinking about this topic, since I have moved to altitude, and am wondering how to adjust interval workouts.
I was out for my long run today, thinking of a workout later this week, and I figured that the variables to tinker with, like any workout, are:
- distance per rep
But I don't really know which. It makes sense to me to keep distance constant, but something's got to give (a bit) and I wasn't sure about changing the speed vs the rest.
For example, if at sea level I'd do 6x1000 @ ~3:00 per, with 1:30 rest, should I allow myself to slow down those 1000s to ~3:10, or aim for the same speed but with longer recovery, maybe 2:00?
furthermore, i am wondering if anyone has the equations that the doctor used in the previously mentioned calculator. i would like to put together conversions for 600m, 1000m, 4k, 8k, etc.
bump it up
5,000feet is 20sec, 6,000feet is 30sec, 7,000feet is 40sec, 8,000feet is 50sec, and 9,000feet is 60sec. on your running times from sea level. hope that is can help you. good luck.
According to the NCAA altitude converter, set to Albuquerque indoor (just under 5000 ft), a 7:45.96 3000m is equivalent to 7:34. And you saw how much Lagat had left and how he had to zigzag through the lapped runners at the end. In other words, my prediction after the 2k at Millrose that Lagat was worth 7:32 or better was on the money. It would be very interesting to see what happens at World Indoor if there is a pacer (e.g. Choge).
For Rupp, who looked quite spent at altitude, but much better than when he was sick two years ago, his 7:37-8 conversion was ungenerous, as a non-altitude born athlete.
And Mary Cain's 4:07 1500m (unpushed at the end) converts to 4:01.62! Unlike Lagat, she is not altitude-born and trained. She has got a great shot of breaking 4 outside this year, particularly if Dibaba and Aregawi are in the field to pull the pace along early.
DOES ANYONE HERE HAVE ACCESS TO A CALCULATOR FOR ALTITUDE ADJUSTMENT. FOR INSTANCE THE NCAA USES ONE FOR TRACK, WHERE CAN I FIND THAT, I HAVEN'T FOUND IT ON THEIR WEBPAGE. THANKS
LetsRun.com Update: You can download the NCAA program which will automatically convert times for you here: http://www.rtspt.com/ncaa/altitude.exe
None of these links work anymore. The runworks won't let you select altitude as ad advanced function. NCAA link no longer exists.
