Four laps. One goal. Infinite energy. Join the community for a series of seeded heats where the focus is on personal bests and pure fun.

The energy hits its peak as the sun sets and the fastest milers in the region take the track. After your race, grab a front-row spot on the rail to witness the speed of the pros.
