Coming in to the finish line of the half marathon

During the Saturday 19 July 2008 half marathon I passed Nett bridge headed outbound into Nett and U at 7100 meters into the race after 47 minutes. After running out into U, I turned around and went back across Nett bridge. As I crossed the bridge headed to Kolonia, I had run 16800 meters in 112 minutes.
