SALT LAKE CITY, Utah — The Union Cycliste Internationale (UCI) has provisionally suspended Matthew Clark, a cyclist from North Salt Lake, Utah for alleged violations of its anti-doping regulations involving anabolic androgenic steroids.
According to the UCI’s official Provisional Suspensions – Anti-Doping Rule Violations and Prohibited list, Clark is cited for alleged breaches of Article 2.1 and Article 2.2 of the UCI Anti-Doping Rules. The UCI listing states that the test date was October 16, 2025, which means it was conducted in connection with the UCI Gran Fondo World Time Trial Championships in Australia, where Clark won the men’s 40–44 age group.
Article 2.1 relates to the presence of a prohibited substance or its metabolites or markers in an athlete’s sample, while Article 2.2 concerns the use or attempted use of a prohibited substance or method.
A provisional suspension means Clark is temporarily ineligible to compete or participate in any cycling activity governed by the UCI while the case proceeds through the results management and disciplinary process. The suspension is not a final determination of guilt.
The UCI has not released additional details regarding the specific substance involved, nor has it issued a separate press release beyond the published listing.
What This Means
Because USA Cycling (USAC) is a UCI-affiliated federation and a signatory to the World Anti-Doping Code, UCI provisional suspensions are recognized across USAC-sanctioned events. While the suspension remains in effect, Clark is not eligible to compete in USAC races, national championships, or other UCI-governed competitions.
Anti-doping rules apply equally across elite, amateur, and masters categories, including Gran Fondo World Championship events, which are subject to UCI testing protocols.
Explainer: The Charges and the Process
Article 2.1 — Presence of a Prohibited Substance
This article covers cases in which a prohibited substance, or its metabolites or markers, is detected in an athlete’s sample. Under anti-doping rules, athletes are held to strict liability, meaning intent is not required for a violation to be established.
Article 2.2 — Use or Attempted Use
This article applies when there is evidence of the use or attempted use of a prohibited substance or method, which may be supported by analytical results or other admissible evidence.
Anabolic Androgenic Steroids (AAS)
AAS are prohibited at all times, both in and out of competition, under the World Anti-Doping Agency (WADA) Prohibited List.
What Happens Next
During a provisional suspension:
-
- The athlete may request analysis of a B sample, if applicable.
- The case proceeds through the UCI’s results management and adjudication process.
- The suspension remains in place unless lifted by the UCI or a competent tribunal.
Any final decision, including the confirmation or lifting of the suspension or the imposition of sanctions, will be published by the UCI and recognized by USA Cycling.
Cycling West will report further developments if additional information is released.
