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"

Trail Port Hill
The singletrack segment called Port Hill, as viewed on Trailfork map of Yellow Loop, is INCORRECTLY named!
What appears on the map is actually Ground Effect, and not the decommissioned Port Hill, which goes down between Ground Effect and 2 Up.
... At present there are rides regularly recorded on it because Ground Effect is valid, whereas Port Hill has been rightly decommissioned, but is located adjacent!
