Corral/Wave Start

We will utilize a corral and wave starting system for the marathon, half marathon, 10K,  and marathon relay. A corralled/wave start will provide a much more efficient and smooth start for everyone.

This year we will be utilizing the Athlinks Smart Corral tool to automate the verification process of athlete start times. It is based on an athlete’s historic results housed in the Athlinks database of more than 265 million race results. This technology uses multiple data points to make sure athletes are placed in the proper corrals.

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.

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.

Health & Fitness Expo

GO! St. Louis is excited to announce its new partnership with Terrain Magazine’s Gateway Outdoor Expo + Summit, resulting in an even better, more interactive expo experience for our Marathon Weekend participants. The expo, taking place March 27 and 28 at the America’s Center, will showcase the best outdoor gear and products, interactive demos, and free sessions and seminars on a variety of active living topics, all in a festive, family-friendly environment.

Pace Team

We offer pace teams for both the full and half marathon led by experienced athletes. Visit the official pace team page for pace groups and bios.

Time Limit Rules

Please note that all GO! St. Louis races adhere to a maximum pace of 14:52 minute per mile. 

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.
