A server is configured to manage a network of participant devices that are distributed across a plurality of participants in a virtually managed competitive event. Events may be configured and offered via the platform, and participants that have devices meeting certain requirements may register for events. Events that have a high goal for accuracy and verifiability may require a smartphone and smartwatch to be possessed and worn throughout the event in order to gather GPS data, step count, heart rate, fingerprint data, facial recognition images, and other verification data before, during, and after the event. Where data cannot be verified and indicates a technical error or falsification of data, participants may be warned, and their results may be flagged to indicate that they are not verifiable and may be erroneous. Event results may be provided for a plurality of participants with information indicating the accuracy and verifiability of individual results.
