Hey I was just in that area umm maybe 2 weekends ago(Garden of the Gods).
We tried to do the Hacket Gulch run for the first time this season and they remade or fixed the trail. That by far is one of my favorite trails to run. The only problem is when they reworked it, it is no longer possible to take the "cheater" sidecuts. You can do this run but only with lockers and/or a winch.
There is also a really cool run up by Downieville/Georgetown area. Not sure of the official name, we just call it the boulder field. We have only done it once and it took us 8 hours to go 6 miles. But It is still open and looks like the sun seems to melt alot of the snow pretty quickly. I checked it out briefly after a day of snowboarding.
If you have the trail book all the info is on those two runs and they pretty challenging and fun at the same time.
