Kiera D'Amato use of poor man's altitude to prepare for Berlin

the benefit of altitude is increased blood volume and hematocrit production. Are you saying that humidity also causes this physiological effect??

Also FWIW, the inability to push hard due to lack of oxygen or due to extreme heat is actually a DETRIMENT to training. Think about it.

People often falsely state the current climate conditions as 90 90. Usually not true. 90F usually goes along with a sunny day. Not too many sunny days with humidity over 90%.

Posters need to stop claiming heat and humidity are poor man's altitude.

I swear by heat training. One of the best falls I ever had came after a summer living in Florida. I trained for 3 months in the Florida heat, a “good” day for me down there was running 6:50s, a lot of my runs were at 7:50 pace and these runs felt exhausting. When I got back to the North I was effortlessly running 5:50 pace on runs, and raced a lot of PRs in some of the longer distance events I used to struggle with (was a mid distance guy in college) I will never forget my first run back up North after living in Florida for the summer. 5:50 pace felt like a jog, it was unreal.

Last year I ran Berlin and it was surprisingly warm, it was 75F at the end of the marathon but kept increasing to 85F that day. Dew point was 66.

I think its a good plan to cover that off for Berlin, might work in her favour come the day.

Aggregate data does not support advantages of training in heat AND humidity. First, the worst distance runners in U.S. are from FL, AL, GA, MS, SC. More elite 5000m to Marathon athletes from MN than from all deep south states combined.

* Current temp., Minneapolis, MN, 67F 50% humidity.

* Current temp. Addis Ababa, Ethiopia, 63F 79% humidity.

* Current temp. Nairobi, Kenya, 72F 53% humidity.

* Kampala, Uganda, 75F 67% humidity.

Posters advocating training in high temperatures and high humidity are either misinformed or are liars.

I respectfully disagree. Until you try it you will never know. A lot of pros have even stated that they have trained in heat or the “poor man’s altitude” and it has helped there running. Your rationale with elite 5000 runners not being from the south often is flawed because most of the kids there race in the heat and never get the opportunity to run in normal temps so they don’t see the benefit. Coupled that with the South’s love for other sports such as Football and you have your answer. Do I think heat is better then altitude training? No. I don’t think anyone is saying that, that’s why it’s called poor man’s altitude, but when you run in 90 degree temps with high humidity all summer then are exposed to normal weather you really do feel a lot fitter and faster.

Higher altitude leads to lower air pressure. Lower air pressure causes things to boil at low temperatures.

did you fail Chem 101?

it's 85 degrees and 76% in humidity right now in Washington DC and I just got back from an 8 mile run. it was a dumpster fire only mitigated by the hope that running in this soup for the last several months has provided some type of fitness benefit. the last few days the humidity has ranged between 75% and 95% - yesterday when I checked it was around 80 degrees and 92% humidity - WTF. I'm from northern Minnesota and this weather is driving me insane, it feels relentless

Altitude expands your oxygen carrying capacity by increasing your hemoglobin mass. Your body then responds to this by increasing plasma volume slightly so overall blood volume is increased. This increases performance (same mechanism as EPO).

Running in the heat/humidity increases your sweat rates, and allows your to sweat earlier in exercise. This will trigger an expansion in plasma volume - but there is limited evidence to suggest any change in oxygen carrying capacity. So this will improve your performance in similar conditions (heat), but not necessarily in all other conditions.

There’s a reason top endurance athletes go to altitude.

Who needs to go to altitude when you're EPO microdosing.
