Free parking is available at the Hamilton Southeastern schools to the north of the start line. Arrive early to avoid congestion! Parking is available in the following locations: Hamilton Southeastern High School Student and Athletic Lots. There is no parking at the start/finish line area!

Gear Check

All participants may check their gear before the start of the race at the Gear Check Area, provided free of charge. Participants can prepackage their gear with the bag you were given at Packet Pickup and seal it with the label available at Gear Check, or a bag may be provided to you on raceday. Your gear check bag will be waiting for you in the truck at the start/finish line in the Rest & Recovery Area. If items are not claimed within 30 days of the event, they will be donated to a charity.


Timing System

Planet Adventure Race will record your official St.Vincent Geist Half Marathon or 5K time with a disposable timing tag affixed to the back of your bib. At packet pick-up, you will receive your official bib with a disposable tag on the backside. Your time starts when you cross the start line and stops when you cross the finish line. As a result, the tag tabulates your “net time,” the actual time it takes YOU to complete the course.

  • DO NOT remove your tag from the back of your bib; NO TAG, NO TIME.
  • The “net time” will be used to determine all age category winners.
  • You do not need to return the timing tag!

Bib Number Requirements

  • DO NOT alter the bib number in any way.
  • Securely fasten the bib number to the FRONT of your running outfit with the safety pins enclosed in your packet.
  • All bib numbers MUST be visible and worn on the front and outside of clothing at all times during the race.
  • Complete the form on the back of your bib, requesting important medical information

Walking Guidelines

If you are WALKING in the St.Vincent Geist Half Marathon or 5K please follow these simple guidelines in order to make your experience more enjoyable.

  • Please start in near your projected pace – by doing so you will be walking with others with the same pace as yourself.
  • Remember, the timing device does NOT start until you go over the starting mats at the start line – therefore you don’t have to worry about how long it takes for you to get the start line once the gun goes off.
  • Do not attempt to move up to a faster pace as this will cause problems.
  • There is a 16 minute per mile cut-off pace that you will need to maintain during the event. This pace will not start until the last person has crossed the starting mats.
  • Please do NOT walk more than two abreast and remember to keep to the right side of the road throughout the course.

Start Line Corrals

Runners will be seeded in starting line corrals according to the letter system to the right. Please line up in your proper corral. If you are running with a friend or family member, make sure you all plan on finishing around the same time. Slower runners and walkers should start near the back of the start to prevent too many passes.


There will be a simple flag warning system all along the course to communicate to participants the status of weather-related or course-related conditions. Flags are located at each mile marker along the course.

  • Green Flag – Everything is Normal
  • Yellow Flag – The heat index is at a point where runners/walkers should slow their pace if they are sensitive to the heat. Participants should be aware of their hydration level.
  • Red Flag – Dangerous weather. Participants should slow down and increase their hydration and if they are sensitive to heat or humidity should not run. Timing of the event has stopped and no awards will be given out at this time. Race Photography and Entertainment as stopped.
  • Black Flag – Race has been cancelled due to extreme weather or course emergency. Events such as lightning, tornado, or human disaster has or is occurring and all participants need to seek shelter immediately. Participants will be evacuated from the route.
