will also eventually feed into the Challenge Loop as mapped in the Governors Creek Mountain Bike Trail
This loop is the longer of the two trails and it serves up some nice, short speed bursts as well as plenty of switchbacks and short climbs. There's also a small downhill rock garden and a jump section, both with clearly-signed bypasses.

which is 0.3 miles.
