QR code for marathon photos: help runners find their race photos fast
Put one QR code at the finish line (and a few smart spots around race day) so runners can scan → take a selfie → instantly see their marathon photos.
TL;DR: Use one marathon photo QR code at the finish line + medal zone. Runners scan with their phone camera, take a selfie, and the gallery shows only their race photos.
This QR workflow became more practical after the 2025 search improvements: FaceFind search moved from a 2.3 second average to under 500 ms, and BibTrack added alphanumeric BIB search for race numbers that include letters as well as digits.
What is a QR code for marathon photos?
A QR code for marathon photos is a scannable code that opens your race photo gallery. Instead of runners typing a long URL or searching through social posts, the QR code takes them directly to the place where they can find their pictures.
The best marathon photo QR flow does two things:
- Zero friction (no app install, no accounts, no typing)
- Instant discovery (runners find their photos in seconds)
This matters most for big races—10K, half marathon, full marathon—where you may have thousands of finishers and tens of thousands of photos.

Where to place the QR code on race day (best spots)
QR placement decides whether your race photo gallery gets 20 scans or 2,000 scans. These spots consistently perform best for marathons and runs:
Finish line + immediate post-finish corridor
- Finish chute exit (runners naturally stop, phones come out)
- Medal zone (everyone pauses for photos)
- Recovery / hydration area (repeat visibility in the first 10–20 minutes)
Expo / bib pickup / help desk
- Bib collection counters (queues = attention)
- Race help desk (“Where do I find photos?” gets answered before race day)
- Photo wall / sponsor backdrop (people are already posing)
Results announcement touchpoints
- Results board / leaderboard screen (runners are looking for their name/time)
- Post-race SMS/email (include the same QR image + link)
- Race website results page (embed the QR code and link prominently)
QR code sizing & design rules (so it scans instantly)
Most “QR code doesn’t work” complaints are simply sizing and contrast issues.
Use the distance rule
A reliable guideline is:
QR size (cm) = viewing distance (cm) ÷ 10
- Table tent (30–50cm distance): 3–5cm code
- Poster (1–2m distance): 10–20cm code
- Stage screen (3–6m distance): 30–60cm code
High contrast, clean background
- Prefer dark code on a light background
- Avoid busy textures behind the code
- Keep a clear margin (“quiet zone”) around the code
Always include a fallback URL
Some cameras struggle at angles. Add a short, readable URL below the QR code (especially on screens).

Event-day checklist (before, during, after)
Before the event
- Print a large finish-line QR poster (and one backup)
- Create one screen slide: “Find your marathon photos” + the QR + “Scan → Selfie → Photos”
- Test scanning at the venue (sunlight + low light if you have an early start)
During the event
- Keep the QR visible for at least 15–30 seconds per screen cycle
- Place a volunteer near the finish-line QR for peak finisher windows
- Upload photos continuously so runners see results immediately
After the event
- Send one post-race message: QR image + link + “Find your marathon photos”
- Review scans by placement to improve signage for the next edition
Privacy & consent (quick guidance)
For races, a simple best practice is to add a short notice near the QR code and on your results page: event photos are captured during the marathon and shared with participants. If your event has a privacy policy page, link it next to the QR code.
For platform-specific details, refer to the privacy policy.

FAQ
Do participants need an app to scan the QR code?
No. Most phones scan QR codes directly from the camera app and open the gallery in a browser.
Should I print one QR code or multiple?
Use the same QR code in multiple places. Repetition increases scans and reduces “where do I find photos?” support.
What if someone can’t scan from the screen?
Add a short fallback URL under the QR code and show the code for at least 15–30 seconds per slide.
How long should I keep the gallery available?
For most races, 30–90 days is a good default. Keep it aligned to your event communication plan and privacy policy.
