The Circuito dos Vales is a road running event that brings together athletes and running enthusiasts in the Vale do Taquari. The project focused on designing a registration landing page aimed at delivering a fast, clear, and highly efficient experience under heavy traffic conditions. The main challenge was to create an interface capable of handling a high volume of simultaneous users within a very short timeframe, without sacrificing clarity or usability. It was essential to communicate race categories, dates, rules, and pricing in a straightforward way, minimizing friction and guiding users confidently toward conversion. The landing page delivered a direct, intuitive, and performance-oriented experience. As a result, 100% of tickets were sold out in just 1 hour, validating the information architecture, visual hierarchy, and conversion-focused design decisions. The project highlights how well-structured UI/UX design can directly impact the success of a large-scale sports event.
