Hardrock Hundred Endurance Run
2024 Course Description- Clockwise Direction
This course description is intended to be used as a general orientation and guide to the Hardrockcourse for runners, pacers and crew. It includes brief descriptions of routes, major drainages, landmark
peaks, climbs, descents and aid stations. Pay attention to alerts and warnings (!). It is not intended to
be used as a navigation tool.
We endeavor to have a well-marked course and provide an accurate GPX file for those that wish todownload it. But keep in mind that this is a huge, complex course. Unexpected things can and will
happen. Marmots devour course markers and pull them into their dens. Elk trample them into themud. Markers have been vandalized, stolen and maliciously relocated. Smartphones glitch andbatteries die.
Therefore, as part of a graduate level run, it is your responsibility to obtain and study whatever maps
or other resources you deem appropriate for your experience level to safely navigate the course ifmarkers or electronic devices fail.
Consider the mile measurements provided herein to be the best aggregation of years of measurements,but know other devices and sources may not always match exactly.
Environmental Preservation is one of Hardrock’s most important values. Practice Leave No Trace
principles. Drop no trash and if you see trash, please pick it up. Never cut switchbacks. Solid humanwaste should be well away from trails, buried 6-8” deep and at least 200’ (70 paces) from thenearest water source.
There are many hazards on the Hardrock course! Including but not limited to: falls on snow, scree,talus and cliffs; fast moving water; wildlife encounters; rock fall; altitude sickness; lightning; cold andheat. While the vast majority of runners complete the course without incident, there have been manyclose calls and occasional injuries sustained from all of the above during the previous editions ofHardrock.
Best of luck! We look forward to seeing you in Silverton.

Silverton Start – Mile 0 – 9318’
From the Silverton School Gym, run north and west out of town, up a half block along 12th, turning left
onto Snowden for two blocks, then right up 10th St to and past the end of the street, up a sloping field,then left onto the Shrine Road. Descend gently on Shrine Road heading out of town, and just before
the steep descent to the highway, turn right (NW) at the junction with the Rainbow Trail. Follow thetrail along and above the highway for just under 2mi, keeping a sharp eye out for markers to descend ashort, steep slope to Highway 550. Caution (!) - look both ways before crossing the road – traffic does
not stop.

crossing!!! This is by order of Colorado State Patrol.
Continue straight across the highway , bearing slightly right into the brush and cross Mineral Creekwith the assistance of a fixed rope. Caution (!)- this is the biggest water crossing on the course. Duringhigh snow run-off years and following heavy rain, this can be a difficult crossing. Proceed generally SW
from the creek, following markers through trees up the Silverton Bear Creek Trail, then above treeline
and Lime Creek. Look (!) for markers indicating a right (north) turn out of Putnam Basin.

Climb #1 – Cataract Putnam Pass – Mile 7.2 – 12,600’
From the pass, drop into Cataract Basin and traverse it to its west end. Slow down (!) and navigate
carefully through here as the trail can be faint and vegetation can obscure the route. Climb up to theprominent saddle.
Climb #2 – Porcupine Cataract Pass – Mile 8.6 – 12,230’
Descend the Porcupine drainage, crossing through high basins and timberline generally NW toward
Mineral Creek on a faint trail, crossing the creek and ascending a short steep slope to FS 585 and the KT
Aid Station.

No crew. No drop bags.
Turn right (east) on FS 585 and proceed 0.3mi to the start of the Kamm Traverse. Angle left, uphill off
the road, wrapping north. Caution (!) – there is a creek crossing in this section that can be tricky withhigh flows. Runners have fallen into swift water here. Ascend steeply a short distance from the creek,
and follow the Kamm Traverse a short distance to its junction with the Ice Lakes Trail. Take a left on
the Ice Lakes Trail, heading uphill.
Follow the Ice Lakes Trail to where it splits between the Ice Lakes and Island Lake Trails, taking the rightfork and continuing to climb until you reach the pass between US Grant Peak on your left and South

Cross over the US Highway 550 tunnel to the Ouray Bear Creek Trail and ascend steep switchbacks.
Trail alert (!) - the Ouray Bear Creek Trail soon enters a steep, narrow gorge. While the trail is generally
good (sans rockslides), there are potential hazards including rock fall, huge vertical drops off the rightside of the trail and potentially difficult stream crossings in the event of heavy rain. Use caution, andlean to the left. The trail is initially well established but grows faint after you reach treeline.
