Believe it or not there was a USATF National Championship held today. Tim Tollefson and Ashley Hawks won the USATF 50 mile trail championships in California.
According to the live thread on LRC events in Placer County California are still allowed to be held with under 250 people. We heard from a participant that the State gave permission for the event to take place as long as shuttles weren't used to take runners to the start (it was a point to point course).
