You’re in for a real treat. It’s the horse shoe, a 15k loop around the west side of the park and then another horseshoe back to the finish line. Although it's not the 50, don't underestimate the amount of climbing and downhill in this one. Disclaimer: expect wet shoes, ankle strain, sandy hands and scratched shins. Be prepared to climb a total of 700 meters/2300 feet.
