I keep forgetting how high Denver is :-(
Went for a quick 5K run before office calls started. Delighted by mid fifties temperature, the sun hidden by a cloud cover and relatively flat roads and dry conditions, I picked up my speed a bit.
In under fifteen minutes, I was reminded of how our geography teacher in eighth grade Mrs. Bhowmic had painstakingly explained why oxygen level and height from mean sea level are negatively correlated for a given location 🙂
I am wiped out!
