This trail begins in Herron Park where Plum Creek doubletrack intersects with the Chase Trail, about 20ft below the Chase Trail singletrack section. Similar to Plum Creek, you'll start by hugging the contour lines on an overgrown logging road that has some very awesome views into the draw below. This is a prime area to spot wildlife since many of the hawks and eagles in the area are frequently hunting this section. This is also the point in the Herron trail system where it makes sense to carry bear spray since this route is isolated and fewer humans are around to scare the furry friends away.
In two miles you'll see the trail shrink down to singletrack and an unmarked trail heading directly uphill on the right. Go right up the steep trail. After the steep section take a left at the dirt road about 100ft to the Southwest until you see the singletrack pick back up on your left.
This section is more of a rough and rocky romp featuring two short but steep and loose climbs. Run through this section until the trail intersects with another dirt logging road. Head left on the logging road until it terminates and you can see the singletrack start up again on your right side and head South. This section becomes a steep, narrow path until you hit a three way intersection and stay right towards Blacktail.
This trail passes through a big 6-way logging road intersection, take the Southernmost and the singletrack picks up again on your left, marked with a pink flag, and heads directly uphill. In 300m you'll hit some logging road, stay left and run it another 300m to the singletrack on your right. From here, the trail sticks with some great singletrack for a while.
In about two miles you'll pop out at a dirt road, cross this and run past the green gate onto the logging road across from the trail. Run this for a while, over 3 miles, it's not singletrack but it's a fun and pretty section to run. Just over 3 miles the trail makes a sharp bend around a draw. Don't follow this, the singletrack continues directly up the draw on your left. It remains singletrack from here. You'll pass the Blacktail to Lakeside Trail
and after that it's a steep climb to the top of Blacktail.
