This is a great trail but much shorter than described. Both my Garmin and Gaia GPS measured the trail at about 13 miles round trip from the parking area. I went straight to Uneva Pass without checking out Wheeler Lake, which I'll do another time.
One of the best trails you'll ever hike and certainly one of my favorites. Yes, it is long. You start at the parking area along I-70 and for the first half-mile to 3/4 mile, the sounds of traffic on I-70 can be heard; the Copper Mountain ski area is directly across I-70 to the south. After the 1-mile mark you've left civilization completely. The trail ascends gently to Wheeler Lakes with views of the Tenmile Range to the east. After that you continue upwards with several flat stretches to Lost Lake. The trail continues with one steep push up to Uneva Pass at 11,900 feet in the final stretch and then you have amazing views of Uneva Peak to the west, the Gore Range to the north, and the Tenmile Range to the east. Well worth it. Allow at least 6 hours to the pass and back and of course, take plenty of water.
