THROWBACK TUESDAY: On this day in 2009, usainbolt set his second world record of the world championships in Berlin, running 19.19, which still stands. Thanks to the folks at nikonusa and the NPS service in the stadium, I got to use a Nikon D3 to get this shot. ©️Paul Merca. All rights reserved. #nikond3 #nikonsportsphotography #paulmerca pumarunning
