The RVA area has an awesome association (
Sportsbackers) that promotes physical activity in the area. They are the organizer of many of our big races. They always have training teams for their races. I used them for marathon training last year, and it was totally worth the cost ($180ish which includes the race fee). They provide a coaches, a training plan, clinics and fully supported weekend group runs. There are 1000+ people who join MTT. Within the MTT, there are teams broken down by avg pace, but it was a wide range. I wound up running with the same 4 people every weekend, and we became good friends. My husband and I switch participation in MTT, and this is his year. I'm going to miss having someone out there to keep me company on those 18 and 20 mile runs.
