Start out along the relatively flat "Reservoir Race", watching out for the steep cliffs beside the track in some sections. Climb up "Wheely Wavey" to the top of Service Basin Spur (There is a bail out point near the top, to shortcut back down "Busy Beaver" if you've had enough!) Descend the far side of the spur down the fast and flowy "Port Hill" before climbing back up "2 Up". Finally descend the many switchbacks of "Busy Beaver" and return to the first section of "Reservoir Race "via "The Birthday Route"
