Subject: Affect of going from sea level to 2000+ feet in above sea level?
So I live at sea level.  I was looking over the changes in elevation for the bike course of Ironman Lake Placid (which I'm doing this year) and saw that the race start/end at roughly 1800 feet above sea level climbing to maybe 2200 feet at one point.  While I know the hills will affect my time (especially since there are few real hills around where I live), will that change in elevation (from sea level to like 2000 feet above sea level) also have any affect on my performance?  I'll be up there 4 days before the race if that affects anything.  Thanks for any input.

From what I remember it can take upwards of two or three weeks to acclimate to elevation in general, and excercise is a whole different story.  I think an elite athlete may have a little bit more of an issue if they were trying to hit a specific time and didn't get acclimated, but for an average athlete looking to finish in a reasonable time it probably isn't that big of a deal.

But there are people here who have done just what you are doing, so I'd defer to them for their first hand experience.

2000 feet elevation? i don't think so. When you get in the area of the Rocky Mountains, where you're looking at 10-12-14k feet above elevation, the oxygen is significantly thinner. But 2000 feet isn't noticeable. I just got back from snowboarding up at big bear where the elevation is about 7000 feet (I think- that's what the road said) and all i noticed on the drive up was a little pressure release in the ears once. no issues w thin oxygen. that i have only experienced when getting over 10-14k in the rockies.

maybe that's just me, but i don't know anyone that's had issues in the northeast w thin oxygen. I'm originally from there and spent many years on the adirondacks, green and white mountains with no issues.

good luck on your race!!

I don't think 2000 feet will be any problem at all.  I live at 8500 feet, do all of my swim training at 6500 feet, much of my run training any where between sea level and 4500 feet(I travel a lot)with some running up at 8500.  Like the previous post said, you will have some issues if you come to Colorado, but not at 2000.

2000?... I would have to say you won't be affected at all. Maybe starting at 5-6K, you might start dealing with something...

but I climbed PikesPeak, and when you're up at 9K or 10K+ feet, now you're talking affects...

I think you should be fine

Depending on who you ask the first marked effect on performance would start occuring around 4K FT ASL.  So I wouldn't be too worried.  You're more likely to see performance issues from the change in humidity if it's way off from what you're used to.

No....you won't see much of an affect till you get around 5000 and only then if you are staying at the elevation long term. Climbing from sea level to a max of 5000 and then decending isn't going to bother you much. Climbing to 5000 and then riding 100 miles at 5000 you might if you aren't careful about hydration.

We do rides here all the time from sea level to 5 to 7000ft and then back down and I don't see any altitude issues if you are prepared.

In general most fit people can go from sea level to 8 or 9000 feet and back down in a day with little or no effect as long as you stay well hydrated. Stay above 7000 to 9000 and it is gonna hurt for a few days. The next bump that hurts even more is 11/12,000 feet. Good idea to get at least another couple of nights rest above 7/9,000 feet if that is your intention.

I use to guide people that lived at sea level and would typically drive to and spend one night at 5000ft. The next morning we'd spend 6hrs or so walking 5 miles to get to 10,000 feet. Dinner and a rest took another 2 hrs before we would hopefully get 6hrs of sleep. Very early the next morning we'd go from 10,000ft to 14,000+ft and all the way back to 5000 by mid afternoon. Something like 1/500 clients would not be able to make the trip from 10 to 14 because of altitude problems. Generally that was exacerbated by lack of sleep, poor conditioning or hydration and not the actual altitude gain.

Like you would do before any major race, eat well, gets lots of rest and you'll no problems and a great time.

2000 feet is nothing to worry about.

I live at about 700 feet, and often drive up into the Blue Ridge mountains for my summer rides (cooler and beautiful). I'm usually riding there at altitudes of 3000-4000 feet and I've never suffered ill effects from the change in altitude.

Ill effects from the climbs, maybe, but not the altitude change

Yeah, no problems.  We do lots of rides from sea level to 2000+ plus in just a few miles.  I am dying at the top from the climb, but not from any lack of 02

We spent the weekend in Truckee, around 7000, and I did notice a bit of shortness of breath when walking around, etc.

But when I did my treadmill workout, I didn't really notice much of a difference in my performance.  I didn't even need to use my inhaler.

2000 is barely noticeable.  You should be fine.
