A start/finish arch has two jobs: define the most important point on the course and give athletes, spectators and sponsors a clean visual landmark. Choosing one by its outside dimensions alone can create clearance, power or branding problems on event day.
Begin with clear route dimensions
Measure the space people actually need to pass through, not just the road width. Account for timing mats, fencing, barricade feet, cones, photographers and emergency access. A running event may need less clearance than a cycling event, while vehicle launches demand a separate assessment.
E-Z UP offers an airtight Aero Inflatable Arch in 13' x 8', 16' x 10', 20' x 12' and 26' x 15' sizes, plus a continuous-air Aero Blower Arch in 20' x 13' and 26' x 16' sizes.
Choose the inflation system
Continuous-air arch
This system uses a blower throughout the event. It works well when reliable power and supervised cable routing are available. Confirm generator policies and protect power connections from traffic and weather.
Airtight arch
An airtight model is inflated and sealed, so a blower does not need to run continuously. That can reduce operating noise and simplify a start line where outlets are unavailable. Follow the inflation and inspection instructions throughout the activation.
Design for athletes, cameras and sponsors
The finish-line approach is the most valuable viewing angle. Keep the event name and primary sponsor readable at speed, reserve smaller marks for secondary surfaces, and avoid crowding every panel. Ask where official photos and broadcasts will be captured before approving artwork.
If sponsors change annually, build the permanent event identity into the main design and discuss replaceable or flexible branding options with the project team.
Plan the complete event zone
- Keep timing equipment and cables out of trip paths.
- Confirm anchoring space on both sides of the route.
- Protect the structure from vehicles and uncontrolled crowd movement.
- Assign trained staff to setup, inspection and takedown.
- Follow the product instructions, venue rules and weather plan.
A coordinated activation may also use an Aero Column for wayfinding, an Aero Bow for a lower entrance profile, or Aero Furniture in sponsor and recovery zones.

Frequently asked questions
What is the best arch size for a 5K or marathon?
There is no universal size. The correct choice depends on clear course width, timing equipment, barriers, camera angles and the number of participants moving through the line.
Can cyclists ride under an inflatable arch?
Choose a model whose verified clear opening suits riders and course equipment, and confirm all route and event-safety requirements with the organizer and venue.
Can one arch serve as both start and finish?
Yes, when the course layout and schedule allow it. Plan the artwork so it reads correctly for both uses and allow sufficient time for any relocation.
