Right from the start, a course profile rises gradually in the direction of the valley of the mountains Lefthand Canyon. The hard climb/growing hill comes at the 8 km mark with a tightening slope of up to 13 %, which goes for 2 km.
Subsequently, the profile slows down slightly and another but shorter climb comes. It is the highest point of the route sitting on the 11,5 km mark at an altitude of 1532 m.
The relieving reward is a beautiful descent to the second split with beautiful scenery and further into the valley along the Left Hand Creek.
Here we come to the lowest point of the route at the 26th km, from where the route heads back south to the Boulder Reservoir - an undulating profile with short climbs.
Watch out for the last two sharp turns - 2.5 km before the finish and 100 m before the finish gate.
There is no special recommendation for pacing, just go and smash it! Be fast, be strong, and drink a lot! :-)
