Does anyone know if there are any attitude conversion charts for the marathon?
Obviously only “actual times” count and you have to take altitude times with a grain of salt, but running a marathon at a mile high altitude (5000ft) must be in the region of a 3-4 minute conversion?
Thanks for the help!
I would guess 8-10 minutes difference. The altitude effect is different for everyone. From my experience 20 sec/mile from 5,000ft to sea level. Fill out this calculator and submit the results- then scroll to section 6.3 for altitude adjustments http://fellrnr.com/wiki/Running_Calculator
Thanks, that’s a pretty useful conversion tool although the conversion for a marathon at 5000ft isn’t anywhere near as generous as 8-10 mins for a guy running approx 2 hrs 30 min - it’s only approx 2 mins 10 sec if I read the conversion chart right.
This seems true as the NCAA altitude adjustment for 10k at 5000ft is around 45 secs (if I’m not mistaken), and since marathon is roughly 4 x 10k , (4 x 45 sec = 3 min) a Mara conversion just less than 3 min makes rough sense to me on account that marathon vo2 intensity is much lower than that required for 10k.
Altitude conversions are for vag
I’d say 5 minutes for a marathon at 5k feet for a 2:3x guy.
Nah, 8 min is about right. I'm a 2:3x guy and my long runs are a good 20 seconds per mile faster at sea level.
This converts 2:35:00 at sea level to 2:42:42 at 5000’. This seems to very closely match my experiences.

I'm pretty fast, my half marathon pace is in the 4:40's per mile. I'm trying to guess what some conversions are from altitude workouts... This Running Calculator is terrible for fast people. It says at 5,000-5,500 feet when I do my workouts near half marathon pace it's a roughly 13 seconds per mild conversion to what I do near sea level... But from my experience I was running pretty comparable workouts. I'd give it five seconds tops, but really they were nearly identical workouts at similar efforts of around 8 miles of a little slower than marathon pace and working down near half marathon pace for a tempo run. No way I had a performance that would be 13 seconds faster, that'd be by far the fastest I've done that workout in my life.
