We’re going to assume that if you’re planning on running in today’s Virginia Ten Miler, you’ve probably already trained and registered although, if you haven’t done the latter, you can do so by clicking  here . Now in its 45th year, the race begins and ends at E.C. Glass High School (2111 Memorial Ave.) and follows a course down Langhorne Rd., onto Rivermont Ave., through Riverside Park, and back. Participants in the less arduous four-mile race take the same route but finish at Randolph College. There will be live music along the route and crowds to cheer on the competitors. The running gets underway at 8 a.m. If you’re interested in volunteering to help at the event, click  here . For general info, click  here .
