Start/Finish Line Arches for Marathons, 5Ks & Triathlons
The Custom Inflatable Race Arch is made for race directors, event producers, and sponsorship teams that need a clear start or finish line structure. It works well for marathons, 5Ks, triathlons, cycling events, obstacle races, and fun runs where lane clearance, sponsor visibility, and fast setup matter.
The arch shows up in every race photo
It often ends up in finisher photos, podium shots, recap videos, and sponsor images. That makes it one of the most visible pieces on the course.
Built for quick race-morning setup
The blower inflates the arch in minutes, hardware is included, and a small crew can usually handle setup without tools. That matters when the road needs to open early and the course has to move fast.
Custom Race Arch Sizes & Widths
The sizes below are based on the angled arch shape. Inner span is the usable road, path, or lane width under the arch.
| Width | Inner Span | Clearance Height | Printable Area | Starting Price |
|---|---|---|---|---|
| 15ft | 10.5' | 7.87' | ~49 sq ft | From $1,045 |
| 20ft | 14.76' | 9.02' | ~75 sq ft | From $1,120 |
| 25ft | 19.69' | 9.68' | ~97 sq ft | From $1,669 |
| 30ft | 22.31' | 11.15' | ~153 sq ft | From $2,159 |
Per-side figures shown for the angled shape. Round and square arches have more printable surface at the same width.
Sizing tip: Most buyers start with lane count and course width. A narrower arch can work for a single-lane trail finish. A 25ft or 30ft option usually makes more sense for wide road races and larger sponsor builds.
Sponsor Branding & Logo Coverage on Race Arches
Most race producers use the arch as a three-part sponsor surface so the race name and sponsor logos each have a clean place to live.
Top Center Panel
The top band usually gets the most attention. On a 15ft arch it runs 5.91' wide. On a 30ft arch it reaches 14.76'. This is usually where the race name or title sponsor goes.
Leg Panels
The legs matter more than many buyers expect because runners see them on approach and spectators catch them from the side. On the 30ft size, each leg gives roughly 53 square feet of printable area.
Removable Banner Zone
The Velcro banner area at the crown is useful when the same arch gets reused across a series or when sponsor messaging changes from year to year.
Continuous Air vs. Sealed Air
The right inflation type usually comes down to power access, event length, and course conditions.
Continuous Air
Best for courses with reliable power. The blower stays on during the event, which helps the arch hold its shape through long race windows and normal wind exposure. You need a standard outlet or a 100v 650w generator nearby.
Sealed Air
Best for remote or off-grid courses. Inflate once, disconnect, and run without a blower. This works well for trail races, field events, and venues where generator noise or power access is a problem. Sealed-air builds are available in 600D polyester only.
Material Options for Event Frequency
Both material options print in full color. The main difference is how often the arch will be used and how hard it will be handled between events.
300D Polyester
3-year warranty. Lighter and easier to pack for annual races or occasional community events. Continuous air only.
600D Polyester
5-year warranty. Better for race operators and recurring outdoor events where the arch will be set up, packed, stored, and moved often. It is also required for sealed-air builds.
How to Order the Right Race Arch
The best starting point is a few details that affect size, layout, and timing.
Course Specs
Share the usable roadway width, target clearance, and whether the arch is for a start line, finish line, checkpoint, or multi-event setup.
Branding + Timing
Send your logo files, sponsor count, and target date early. Most buyers should still allow 2 to 3 weeks overall for revisions and shipping.

If you need additional water-course markers around the same event, pair the arch with custom inflatable buoys. For broader branded entrance options, see the inflatable arches collection.
Frequently Asked Questions
How much does a custom race arch cost?
Pricing starts at $1,045 for a 15ft continuous-air arch in 300D polyester. The top end is about $4,250 for a 30ft sealed-air arch in 600D. Width and inflation type drive most of the price difference.
How much branding area do I get?
That depends on width. A 15ft arch gives roughly 49 square feet across the top panel and legs, while a 30ft angled arch gives roughly 153 square feet. Larger sizes give you more room for a race name across the crown plus sponsor placements on the legs.
How long does production take?
Production is usually 5 to 8 business days after artwork approval. Most event buyers should still plan for 2 to 3 weeks overall so there is time for revisions, shipping, and any last sponsor-logo changes.
What artwork do you need from me?
Vector files such as AI, EPS, SVG, or PDF are ideal. High-resolution PNG or JPG files can also work if they are large enough. If the arch includes multiple sponsor logos, it helps to collect those files before the layout starts.
Can the arch handle wind?
Yes. Stakes, D-rings, and tie-down ropes are included for anchoring. Continuous-air arches hold their shape well because the blower keeps pressure in the structure during the event. For sealed-air arches or more exposed venues, many buyers also add weight bags at the base.
Can I reuse the arch for multiple events?
Yes. Many race operators use the same arch across a full season. A 600D build is the better choice for repeated travel and setup, while a 300D version makes more sense for a once-a-year race or lighter schedule.
