PhysioNet supports open challenges, which invite participants to tackle clinically interesting questions that are either highly topical or neglected. Since the launch of PhysioNet in 1999, it has co-hosted an annual challenge in collaboration with Computing in Cardiology.

If you are interested in working with PhysioNet to organize a challenge, please contact us (contact@physionet.org). You may also independently host a challenge on PhysioNet by submitting a challenge description via project submission system. Once published, the information about your Challenge and the project code and data will be made available to the public.

Formerly known as the PhysioNet/Computing in Cardiology Challenge, the George B. Moody PhysioNet Challenge runs from Jan/Feb through August each year. For details of this year's event, please see the Current Challenge Site. A list of past Challenges with links to outputs (open source code and open access data), can be found here.
