The beginning of this is familiar to many because it incorporates the long climb/descent at the southern portion of the main Sunbridge Trail loop. This portion of the loop was reopened in early 2016.
The bottom, below the lower intersection, has been a main invasion route for quads and motorcycles. That was cleaned up to extend the downhill to the absolute limit of our local hills. Unfortunately, the lower segment was too steep for most people to climb back to the main intersection and the need for the return climb arose.
The run begins at the intersection of The Comeback Trail
and Sunbridge Hills Conservation Area
loop trail within feet of Huntoon Road. Out of town riders would have driven by the unmarked trailhead on their way to the main parking lot. Parking is allowed but it's VERY important not to block the access of water company vehicles that actively use that area. Roadside parking on the grass is allowed to the south at another trailhead (not included on the map, yet) a very short distance away.
The opening stretch is a beginner level cruise with a couple turns that make higher speeds interesting. Then, there is a long wide open straight where pedaling is optional. A tiny, beginner drop and an ever-present drainage ditch add some spice to the run when in the smallest cog. As things start to get blurry, and one begins to feather the brakes, the tree appears.
A large tree had fallen years ago. A small gap was cut that helps keep the quads out. The approach to the gap cuts across the drainage to the left resulting in a tight right that one must pedal hard to recover speed. Once up to speed, the rocks begin! Hold on and ride within your limits.
Just after it flattens out at the main intersection of Upper River Bluffs
trail, it gets steep. The quads have provided a bit of berm to aid the ride down. But the rocks get a bit bigger, too.
Within sight of the railroad at the bottom of the hill, the return climb begins across the drainage on the right. There is a brief, narrow, technical bench cut climb to a mellow but slightly technical un-benched section. The climbing is rewarded by a tech traverse, to a fairly big drop into a flowing dirt ribbon with a boulder thrown in for fun.
Then, the climb resumes. There are some tight spots and some rock thrown in, and a little bit of exposure, but nothing gnarly. The trail wraps around large limestone rocks before ending at the main lower intersection.
