What about the wind?
I am in Tulsa, OK this week and guess what? It is windy! The wind is a constant in this part of the world. We had some decent weather today and I headed to the Memorial High School field in Tulsa for some running on their 6 lane track. Decent weather here is 15 to 18 MPH wind, 11% humidity and 60 degrees at 4:00 PM. The wind on this track is typically right down the front stretch, which is also shady. To stay as warm as possible, I do my work in the sun on the back stretch. Today I worked on 100 meters repeats on the synthetic turf into the wind. I brought my parachute, but it was not needed. I ran four 100 meter repeats into the wind and after getting some pretty good work, I got out my stopwatch and timed two 100 meters into the wind--15.94 and 15.90 were the times. I then ran two sets with the wind with similar effort and that was different....
