My last post was the marathon race report, but I have been training since the race. Since the race I have done some research about how much a headwind can effect performance and I have been amazed at how much even one of 5 mph can make a huge difference. There were headwinds from 6-16 miles (crazy bad from 10-16) and again really bad from 19 to a little after 21 miles. I don’t know how accurate these calculators are, but the one at RunWorks and another showed a 10 mph headwind was worth as much as :20-:30/mile. This sounds a little extreme….,but the sustained winds during the race were at 10-15 mph with 25 mph gusts! Knowing this makes Chris Zablocki’s 2:17 even more impressive!
Can any physicists out there give a more detailed answer?
I have been running since the race and I have updated my training on the training page. I am looking at running another marathon in mid-late May. I will post my decision soon….
