Embark on the Double Down Challenge (DDC) adventure, beginning with the 4 Miler at 7:15 AM. Complete the 4 Miler, and then head back to the start line to begin the Mountaineer 10 Miler! PLEASE READ: Participants will need to begin the Tar Heel 10 Miler portion of the Double Down Challenge by 8:00 AM. Double Down participants will need to maintain a 10:35 minute mile pace to return to the start line by 8:00 AM. The 10 mile segment of the challenge must be completed by 10:35 AM. Note there is a .25 mile run from the 4 mile finish line to the 10 mile start line. You must complete the 4.25 miles by 8:00am (10:35 min/mile pace) A pacer will be available for DDC runners during the 4-mile portion as a general pacing guide. While staying ahead of the pacer is intended to help runners remain on track for the cutoff, pacing may vary and is not guaranteed. Best of luck to all runners who will get after the Double Down Challenge!
