Anti-doping controls in the triathlon world have never reached epidemic levels like in swimming, cycling and running. It’s a wonder how much cheating has slipped through the cracks over the decades as testing hasn’t been as rigorous as some claim it should be. While instances of doping do pop up from time-to-time, are triathletes simply more honest and moral than athletes in other sports, or is it high-time race organizations and federations took their responsibility more seriously and upped their game?

The Challenge Family thinks so. It has announced it will level-up its effort to catch pro and amateur dopers for 2025 Challenge Roth. More tests will be administered ahead of the race, and a new type of test will be launched. Dried Blood Spot (DBS) tests will accompany an education campaign delivered in partnership with the German National Anti-Doping Agency (NADA).

Administering DBS samples

DBS testing involves taking a small sample of blood from capillary blood vessels in the skin, versus a vein. It is then blotted and dried on paper and analyzed in a lab. It is superior to urine samples as more prohibited substances can be detected in the blood. It is also less invasive and requires less technical ability and equipment than taking a blood sample through a vein, which can be painful for the subject, and requires skilled technicians and cold storage.

The United States Anti-Doping Agency has been piloting the practice for a few years. The new type of testing is making it simpler, cheaper and more accessible, which has paved the way to increased testing levels. That path has meandered its way to Germany for Challenge Roth on July 6. Testing methodologies will continue to include urine samples as well, as the organization expands it anti-doping program across the board.

What to expect about being tested

Testing will begin for pros and age groupers starting the Thursday ahead of the race on Sunday. NADA will be on-site taking samples at the Expo. It is being rolled out both as a doping deterrent, but also an opportunity to inform the wider athlete community about fair play and testing methodologies.

The organization hasn’t released the number of athlete it intends to target, or how they will select individuals to be tested. For a full list of banned substances and methods list visit: https://triathlon.org/news/wada-publishes-2025-prohibited-substances-and-methods-list
