The course is an out-and-back. The lower 0.8mi is paved and the upper 2.3mi a dirt road. The dirt road is 2wd, steep, but with decent footing.

Start on 23rd ave, just N of Colorado Blvd, over the river, by Courtney-Ryley-Cooper Park, in Idaho Springs. Go up two blocks and turn left onto Virginia St. In ~1/4mi, go right up Virginia Canyon Rd. Here is where the climbing really begins. Go up Virginia Canyon Rd for 1/2mi to the junction with Virginia Canyon (aka Oh My God, OMG) and two Brothers Rd.

This was just the warm-up. From here it goes from just steep to very steep, from paved to dirt.

Continue straight onto Two Brothers Rd. It's a mile up a fairly consistent 12% to another junction with OMG. Continue straight up Two Brothers. The next mile or so has some stretches >15%. The road curves right and flattens out some towards the top.

Turn at the aid station, just before the paved road,

Now that you've run your slowest 5km, run your fastes back the same way. The road is steep and there are a few streteches where there are small wash-outs and the gravel is loose, but otherwise the footing is pretty good.
