As the loops added up, the toughness of the race became to show itself. I believe that the saving grace for all of the runners was the overcast skies.
Once it started to get light, many of us were able to see the true beauty of the course as many of the runners had never run the trails & were NOT from Tulsa. Unfortunately when it comes to hills, they seem easier when you cannot see them & you anticipate them when you know when they are coming.We were also blessed with lower than normal temperatures & even a hard rain (that seemed to persist for the last 20 miles). The cooler weather was a much welcome reprieve from the usual roasting Oklahoma summer. I suspect if it were a "normal" summer day, there would have been plenty of people dropping as the heat climbed.
