Start by the parking lot and head W, up a gradual rise, on the wide, smooth path. At ~200m, go left, downhill (you'll be finishing from the other side). The trail rolls to the start of the incline. You'll reach a few wooden berms. This is not yet the start of the real incline. The real incline has consistent steps of varying length and height. For the most part, they're spaced too far apart to maintain one stride/step for long, but too close to do two strides naturally. Have fun.

Shortly after the top of the incline, take the first left. This is 0.5mi. The trail starts flat, drops a bit, then gradually rises for the next ~0.6mi. There's a slight crest, one of the two high points. It then drops gradually for ~0.3mi.

At ~1.5mi, the trail turns left, downhill, under Hess Rd. The trail then rolls uphill to the start of the loop at 1.9mi. There will be an aid station there.

For 2025, we'll run the loop counter-clockwise, reverse of last year.

CCW: Stay straight. The trail rises gradually, past 2.0mi and the other high point. It then gradually descends over the small crest. Enjoy the panoramic views of the front range. The trail curves left as it drops moderately into a canyon. It rolls and winds a bit, then climbs moderately back out. You have ~1/4mi of flat terrain. Then, it drops for ~1/3mi, towards the reservoir. This is moderately steep and somewhat rocky. After a bit of flat, it rolls up towards the end of the loop. The last part of the loop is flat, back to the aid station.

At the end of the loop, 4.3mi, go right and return the way you came out. The trail rolls down, then climbs back under Hess Rd. After passing under Hess, the trail turns right and rises gradually back up. Continue back to the trail near the top of the incline.

There, ~5.7mi, go left (don't go down the Incline). The downhill is steep but smooth. There are no stairs, just several dirt bumps (to slow bikes). It drops in two pitches with a flattish section in between. Near the bottom, go left for a ~200m sprint to the finish.
