Mountain bikers refer to this trail loop as "The 666" because it's 6.66 miles of challenging rocks, roots, and rolling hills (550 feet of climbing per lap). The loop consists mainly of singletrack with a sprinkling of double-track and dirt road. 
We'll give you 400 minutes (that's 6.66 hours) to complete as many laps as you dare before your time is up. Any laps finished beyond 400 minutes will not count. The most laps in the fastest time under 400 minutes wins.
