BREAKING - it looks like the England game will be pulled forward, due to the threat of thunderstorms.
I believe that makes it warmer though
It doesn't look too hot there though.

I mean there's this big discussion around the altitude but I've climbed many mountains and never really struggled but as you get above 10,000 feet and towards 15,000 feet, obviously things get a lot harder. Below that I've never really felt anything.
I did ask AI though and this is what it returned.
7,000–8,000 ft
This is where things become interesting.
Around 7,200 ft (about 2,200 m)—roughly the altitude of Mexico City—many people experience:
breathing becomes noticeably heavier
recovery between repeated efforts slows
aerobic capacity falls around 10–15%
heart rate rises during exercise
dehydration occurs more quickly
decision making under fatigue becomes harder
This is why altitude becomes a major factor in sports such as football.
A football example
At 7,200 ft, a footballer who normally covers 11 km might still complete close to that distance, but:
fewer high intensity sprints
slower recovery after pressing
reduced repeat sprint ability
earlier fatigue in the final 30 minutes
more tactical pacing of effort
This is why teams playing in places such as Mexico City, La Paz or Quito often have a measurable home advantage, especially against visitors who have just arrived.
For the altitude you asked about earlier—around 7,200 ft—it's best thought of as the point where altitude shifts from being a subtle physiological factor to one that has a clear and measurable impact on endurance sports without yet posing a serious health risk for most healthy people.
