Once a year, the students of Leuven congregate to run like hell. Teams of students compete against each other in a 24 hour relay race. ULYSSIS is a student organisation that voluntarily provides many IT services for other students, like providing the automatic lap counting system at the 24 hour run, using their own software called i++. This talk will describe how this lap counting system works and describe the dream I have of a cheap user-friendly system using free and open source software, that would enable other organisations to organise similar events.
