You will gain 4392 feet (1339 metres) in elevation, requiring an estimated 5 hours and 42 minutes to complete.

Prepare for changing road conditions on this route; the lower sections of Henson Creek (CR 20) from Lake City are generally graded gravel, suitable for many bikes. However, as you ascend towards Engineer Pass, the road becomes rougher, rockier, and intensely steep in places. Given the high elevation, reaching 12,800 feet, you should be ready for the physical demands of mountain biking at altitude. Plan your visit carefully to account for these challenging conditions.
