How it works

- Open the event on Smoothcomp.
- Click Register.
- Fill in the coach’s details and upload the athlete’s signed Universal Athlete Declaration (PDF).
- Choose the discipline(s) and weight class.
- Confirm the registration by 30 September 2026, 23:59 (Tallinn time).
The same instructions as a document:
Registration Instructions (PDF)Athletes
You upload exactly one document. Everything medical travels with you on paper.
What you upload: one document
The Universal Athlete Declaration is the one form every athlete signs. Download it, read it together with the rulebooks published on this page, sign it and upload the PDF during Smoothcomp registration. One declaration covers all disciplines you register for.
Sign digitally (ID-kaart or Smart-ID) or print, sign and scan. Athletes 18 and older sign for themselves; a club or coach cannot sign for an athlete.
Universal Athlete Declaration (PDF)What you bring on paper
Bring the originals to accreditation in Tallinn. Nothing medical is uploaded; the medical team inspects your papers in person and returns them.
| Document | Who needs it | Validity |
|---|---|---|
| Medical certificate from a licensed doctor stating fitness to compete in full-contact sport. Template: Medical Certificate (PDF) | Everyone | Issued within the last 12 months |
| Blood test: HIV 1/2 Ag+Ab, HBsAg, HCV Ab. Negative, on laboratory letterhead with signature | MMA: all athletes · Muay Thai: athletes 16 and older | MMA: taken within the last 12 months · Muay Thai: taken within the last 6 months |
| Dental brace certificate from your orthodontist | K-1 athletes with braces | Current |
| Photo ID (passport or ID card) | Everyone | Valid |
- K-1 athletes need no blood test.
- Competing in both MMA and Muay Thai? Take the blood test within the last 6 months, then one test covers both.
- No valid papers at accreditation means no competition. There is no on-site testing.
Athletes under 18: for the parent or guardian
Before signing anything, read the Risk Information Sheet. In the declaration you confirm that you have read it.
Risk Information Sheet for Parents (PDF)A parent or legal guardian completes and signs the Universal Athlete Declaration for the athlete. Athletes aged 12–17 also sign their own assent line. Guardian contact details are required and must be reachable on competition days.
Coaches and clubs
Every coach signs the Coach Declaration. The club sends its coach list, and each coach sends the signed declaration, to info@theclash.ee by 30 September 2026.
Coach Declaration (PDF)Coaches cornering athletes under 18 also attach a criminal-record extract, issued within the last 12 months by their home country's criminal-records authority. The same rule applies in every country, including Estonia. Verification happens before the event; nothing is brought on paper to the venue.
At accreditation: an ID check against the submitted declaration, then the coach pass (wristband). A maximum of two cornermen per athlete. Without a verified declaration there is no coach access to the festival.
Clubs registering athletes: the Universal Athlete Declaration is signed by the athlete personally, or by their parent for under-18s. An unsigned or club-signed athlete declaration is not valid.

Yes. But the declaration must be signed by you, or by your parent if you are under 18. A form uploaded without a signature, or signed by the club, is not valid.
-
Register for each discipline in Smoothcomp; one signed declaration covers them all. If your disciplines are MMA and Muay Thai, take your blood test within the last 6 months so one test covers both.
-
Print the declaration, sign it by hand and upload a scan or clear photo. You confirm your signature in person at accreditation.

The accreditation and medical-check schedule is published closer to the event. Questions in the meantime: info@theclash.ee.
