We will utilize a corral and wave starting system for the marathon, half marathon, 7K, and marathon relay. A corralled/wave start will provide a much more efficient and smooth start for everyone. All participants will be assigned corrals based on estimated finish times submitted during the registration process.
Race bibs will designate your assigned corral for the race with a letter (A,B,C or D, etc.) which is located on your bib. If no estimated finish time is provided for the marathon, half marathon or marathon relay, the participant will be automatically placed in the final corral.
There will be multiple waves on race morning to space runners out so all can fall into their own running rhythm. The first wave will be at 7:00am. Each successive wave will be separated by one minute. When the start of the race is announced, Corral A will be released. Corrals B, C, and D will remain at the start. At one minute intervals the next corral will be released. Participants may move back in a corral/wave (i.e. from B to C), but may not move up in a corral/wave (i.e. from C to B).
Individual times will not activate until a participants timing tag crosses the timing mats.

Time Limit Rules
Marathon Weekend: The marathon course route re-opens to traffic at a rolling schedule according to a 6.5-hour marathon pace or (14:52 minutes per mile). Marathoners and Half Marathoners must maintain a 14:52 minute per mile pace throughout the race. The time limit rules will be strictly enforced.
There will be a pace leader leading a 6 hour 30 minute marathon pace or 3 hour 15 minute half marathon pace (14:52 minutes per mile). The time limit will begin when the 6:30 marathon pace group crosses the start line after the start of the race. Anyone who falls behind the last pacer, leading 14:52 min/mile must get into the sag wagon and be transported to the finish, or move to the sidewalk and obey all traffic signals.
Any Marathon or Marathon Relay participant who falls behind the pace (behind the 6:30 pace group) prior to the Half Marathon turn to the finish, will be required to finish with the Half Marathon. Any marathoner, who turns at the half marathon split and completes the half marathon, will receive finish line amenities (food, water, medical assistance if needed).
After the half marathon turn to the finish, course support (police, course monitors, and water stations) will not be available to marathoners or marathon relay teams who fall behind the 14:52 minute per mile pace. Anyone who falls behind the pace must get in the sag wagon and will be transported to the finish line, or move to the sidewalk and obey all traffic signals.
Marathoners who only complete the Half Marathon will not be eligible for overall or age group awards.
