Last night I have heard that there was a serious accident on the Custis.I went through the Custis from Rosslyn to Lyon Village just before 7 pm. At that time, a jugging club was FLOODING the trail with participants. It was CRAZY. They were jogging three wide. They were jogging on the left, into oncoming traffic. They were not heeding passing calls.
I have worked with a volunteer group that used to do 5Ks on the WOD. And no matter how hard you coached people, and no matter how many event marshals you used, with a crowd that large there was always people who did not follow good trail etiquette, creating extremely dangerous situations.
