Marathon & Race Medal Production: A Guide for Race Directors

Marathon and race medal production involves more than approving a visual design and waiting for delivery. For race directors ordering custom race medals, every production stage affects timeline, quality and bulk consistency: artwork proof, mold planning, zinc alloy die casting, deburring, polishing, plating, coloring, UV printing, ribbon assembly, QC, packaging and shipping. This guide explains how the factory production process connects to procurement decisions, helping event teams confirm the right specifications, sample proof, inspection points and delivery schedule before race day.

Race medal production is a delivery chain, not a single manufacturing step. If the artwork, mold, plating, ribbon or packing details are unclear, the project can face rework, delay or quality variation. Race directors do not need to become engineers, but they do need to know which production points must be confirmed early.

Key Takeaways:

• Race medal production should be planned from the confirmed event date, quantity, design complexity, sample approval method and delivery deadline.
• Marathon running medals often require stronger mold planning because city landmarks, 3D relief, route lines and sponsor logos must be converted into manufacturable metal details.
• Zinc alloy die casting is commonly used for custom race medals because it supports custom shapes, 2D/3D relief, plating, enamel, UV print and structural add-ons.
• Plating, coloring, UV printing, ribbon assembly and packaging should be treated as production stages with separate QC checkpoints, not as small finishing details.
• Race directors should request sample photos/videos and pre-shipment inspection proof before bulk delivery, especially for large events with fixed race dates.

Why Race Directors Should Understand Medal Production

Race directors do not need to know every machine setting inside a factory. But they do need to understand how production stages affect approval time, sample quality, bulk consistency and delivery risk.

A marathon medal is connected to a fixed race date. If the mold detail is unclear, plating color is not confirmed, ribbon direction is wrong, or packaging is approved too late, the problem may appear when there is no time left for correction.

The production process is also a decision map. A 5K medal with a simple logo may need a standard mold, bright plating and soft enamel. A city marathon medal may need 3D relief, antique plating, multiple QC angles and stronger packing. A sponsor-heavy race medal may need UV print or back-side printing.

Badge Artisans has manufactured custom medals since 2010, and one recurring lesson is simple: projects run better when production decisions are made before sampling, not after the first sample reveals missing details.

Step 1 — Convert Race Design into Production Artwork

Race medal production starts when event branding becomes a production-ready artwork file. A race poster, registration page graphic or sponsor deck is not automatically ready for mold making or UV printing.

The production artwork must clearly show medal size, thickness, front design, back design, plating color, enamel colors, print areas, ribbon artwork, attachments and any special finish.

For marathon and race medals, the most common artwork sources are event logos, route maps, city landmarks, sponsor logos, finisher wording and campaign colors. These elements must be simplified for medal scale. A detailed city map may look impressive on a poster but become unreadable on an 89mm medal if every street line is preserved.

Production artwork should also separate the front medal design, back medal design and ribbon design. Sponsor logos should be supplied as separate high-resolution files whenever possible. If a back side includes many sponsor logos, the sample stage should include close-up proof.

Artwork proof can be completed within 24 hours at the fastest when the buyer provides clear files and requirements. However, fast proofing does not replace careful checking. The race director should confirm spelling, date, distance, logo order, sponsor placement and ribbon direction before moving to sample production.

Step 2 — Mold Planning for Marathon and Running Medals

The mold controls the medal’s shape, relief, hanging hole, edge structure and major metal details. Once mold work begins, changes to size, shape, relief depth or hanging position may add time and cost.

For marathon medals, mold planning is especially important because many designs include city skylines, bridges, mountains, route lines, year marks, sponsor areas or 3D commemorative details.

2D relief is usually suitable for logos, text, simple icons and geometric lines. 3D relief is better for city landmarks, mountains, bridges, route topography and commemorative elements. For marathon medals, 3D relief can create a stronger sense of place because the medal can show a landmark through real depth and shadow.

The hanging hole is not a decorative detail. It affects how the medal hangs when the ribbon is attached. If the hole is off-center or the medal shape has uneven weight distribution, the finished medal may tilt when worn. This should be reviewed during mold planning, especially for irregular shapes.

Cut-out areas and thin bridges also require attention. A cut-out design may look light and modern, but if the metal bridge is too thin, it can affect strength, polishing and plating consistency. Spinner and interlocking designs should be reviewed even earlier because they involve assembly tolerance and movement clearance.

Step 3 — Zinc Alloy Die Casting and Metal Body Production

Zinc alloy die casting is commonly used for custom race medals because it supports complex shapes, 2D and 3D relief, custom thickness, plating, enamel filling, UV printing and structural features.

The quality of the metal body affects every later step. If the die-cast blank has rough edges, air holes, incomplete sharp details or heavy sprue marks, polishing, plating and coloring become harder to control.

Zinc alloy melts at around 385°C, making it suitable for die casting into detailed custom medal molds. After casting, the blank needs sprue removal, deburring and edge preparation. The goal is to remove unnecessary metal from the casting process while keeping the medal’s intended details intact.

Machine tonnage matters for larger medals. If the pressure is not enough for the medal size or relief complexity, sharp corners and fine details may not fill properly. Mold venting also matters because trapped air can create pores or surface defects. Too much release agent can affect small textures by preventing the molten metal from filling fine details cleanly.

Race directors do not need to inspect the die casting machine, but they should understand why sample photos are important. If the blank detail, edge or relief is not stable during sample production, the issue can repeat in bulk.

Step 4 — Polishing, Plating and Surface Finish Control

After die casting and deburring, the medal surface must be prepared for plating and later coloring. Polishing affects edge smoothness, surface reflection and how cleanly plating appears.

Plating is not just a color choice. It affects the medal’s final tone, contrast, perceived quality and compatibility with enamel or printing.

Before plating, the medal surface usually needs cleaning, degreasing or wax removal. Polishing residue can affect plating adhesion if it is not removed properly. In production, surface preparation may include ultrasonic cleaning, water rinsing and other pre-treatment steps before the plating layers are applied.

For some plating processes, copper layers are used to improve surface brightness and plating stability. Acid copper time can vary based on the required finish, with 20–60 minutes used as a reference in production planning. After plating, medals may go through drying in a tunnel oven at approximately 100°C for about 40 minutes.

Antique finishes are often used for marathon, trail and commemorative medals because the dark recessed areas make relief details more visible. Bright gold or bright silver works well for 5K, 10K and community events. Black nickel and matte black can create a modern look, but logo contrast must be checked carefully.

For finish selection, see our race medal plating options guide.

Step 5 — Coloring, UV Printing and Special Finish Production

Once the metal finish is ready, the visual details are completed through enamel filling, UV printing or special finishes. This stage turns the plated metal body into a recognizable event medal.

The technique should follow the design. A logo-based medal, sponsor-heavy medal and night-run medal may all require different surface solutions.

Soft enamel is widely used for race medals because it works well with solid colors, raised metal lines, race logos and distance marks. Hard enamel provides a smoother surface and is better suited to simple, clean artwork. UV print is useful when the design includes many sponsor logos, gradients, photos, maps or full-color artwork.

Special finishes can support event themes. Glitter works well for fun runs, holiday races and women’s events. Glow-in-the-dark areas are useful for night runs and Halloween themes. The glow effect comes from glow pigment or glow enamel, not from UV printing itself.

For UV printed areas, epoxy may be used to protect the printed layer and add gloss. Buyers should check close-up clarity, color appearance, print alignment and epoxy quality during sample approval.

Step 6 — Ribbon Assembly, Accessories and Packaging

A race medal is not finished when the metal body is completed. Ribbon assembly, attachments, packaging and carton marking are part of the production delivery.

These details affect wearing balance, sponsor visibility, scratch prevention, warehouse receiving and event distribution.

For 5K and 10K medals, a 25mm ribbon is often practical. For heavier marathon, trail or obstacle medals, 30mm or 38mm may provide better balance. Ribbon length usually falls within 800–900mm, with 860mm and 900mm commonly used depending on event type and wearing preference.

Full-color sublimation ribbons can include race name, date, sponsor logos, distance marks or event colors. Ribbon direction should be checked with the finished medal, not only as a flat artwork file.

Packaging should match the delivery method. Individual polybags reduce scratches in bulk shipment. Pouches, boxes or backer cards may be used for VIP events, charity programs, virtual runs or sponsor-heavy campaigns. Carton marks should include event name, quantity, PO or destination information to help receiving teams sort the order efficiently.

Step 7 — QC, Sample Approval and Pre-Shipment Inspection

QC should happen at multiple points, not only at the end. A race medal can pass front-view inspection and still have problems with side thickness, ribbon direction, plating marks, UV print clarity or packaging.

For race directors, sample approval and pre-shipment proof are the main tools for reducing production risk.

For 3D relief medals, request angled photos because light and shadow show depth more clearly than a flat front photo. For UV printing, request close-up proof of small logos, maps or sponsor details. For plating, check scratches, black spots, color consistency and oxidation risk.

Ribbon assembly should be checked after the medal is complete. The ribbon should face the correct direction, the ring should be closed properly, and the medal should hang in a stable position.

Badge Artisans uses a 3-stage QC process covering blank inspection, semi-finished inspection and final inspection. For race medal projects, final QC also includes ribbon assembly, packaging, carton marks and pre-shipment proof.

Production Timeline and Delivery Planning for Race Events

Race medal production should be planned backward from the event date. The production timeline must include artwork proof, sample approval, bulk production, accessory assembly, QC, packing and shipping.

The more complex the medal, the more buffer the race director should build into the schedule.

For physical marathon events, 6–8 weeks before race day is a safer starting point for medal production planning. If sea shipping, custom packaging, spinner structures, interlocking medals or complex 3D relief are involved, start earlier.

Rush production may be possible, but it requires discipline. Freeze the artwork quickly, reduce structural complexity, approve samples through photos or videos when appropriate, and choose air shipping if the deadline is tight. Late changes to ribbon, sponsor logos, plating or packaging can create avoidable pressure.

Race Director’s Production Checklist Before Bulk Order

Before bulk production begins, race directors should make sure every production-critical detail is confirmed. A clear checklist helps prevent last-minute changes after mold work, plating, coloring or ribbon production has already started.

Use the checklist below before approving the bulk order.

If one checkpoint is not confirmed, treat it as a production risk. For example, if the medal shape is approved but the ribbon width is not, the finished assembly may look unbalanced. If the plating color is approved from a digital mockup only, the physical finish may not match the event team’s expectation.

A race medal project is easiest to control when production details are frozen before sample or bulk production. That gives the factory a clear standard and gives the race director a reliable basis for inspection.
