Directions: From I-25, take exit 199 (Belleview). Turn east at the end of the exit ramp and drive approximately 1 mile east on Belleview to Yosemite (there will be a stop light). Turn left on Yosemite and drive approximately 0.5 miles to Campus Drive (on your right). Parking staff will direct you to parking in the Cherry Creek High School SOUTH parking lot. Please do not park in any other lots, as all other school lots have been reserved for events at the high school on race day. Also, there will be no race parking inside the park. Once parked, you will walk into the park. You will see the start/finish area at Hobie Hill on your left approximately a quarter mile past the entrance station. The walk from parking to the stert/finish area will take about 15 minutes. Please plan accordingly so you do not miss your start. We will have a bag check area at the start line, so you do not have to walk back to your car.
Packet Pickup: We will have early packet pickup and race day packet pickup options in 2017.
- Early Packet Pickup will be held at Runners Roost Lakewood from noon until 6:30pm on Friday April 21st.

Start Procedure & Cutoff Times: Racing Underground utilizes a 2-wave start procedure for its half marathon distance events - the 'Official' start time, and an optional 'Early' start time for athletes who will take more than 2 hours and 30 minutes to complete the course.
The Official start time for the Three Creeks Half Marathon is 8:00am. The optional Early Start time is 7:30am. All runners and walkers must complete the course by 11:45am. This means early starters have 4:15 to complete the course, and 8am starters have 3:45 to finish. All finishers, regardless of wave, will be listed in the official results and will receive a finisher medal.
Why do we do this? There are two reasons why we use this two wave start procedure. First, the early start allows our slower runners to enjoy a better finish line experience, with more spectators on hand to cheer them in. The second reason is for course logistics.
There are no requirements to enter the 8am start, except that you must finish faster than 3 hours 45 minutes. If you are a 3 hour half marathon runner and you would like to start in the 8am wave, then you are welcome to start in the 8am wave.
The 7:30 Early Start requires that you MUST take longer than 2 hours 30 minutes to complete the course. If there is a chance you will run faster than 2:30, then you should start in the 8:00am wave. Early starters who run faster than 2:30 will not appear in the race results.
