National Auto Sport Association Utah Round 5 weekend at Utah Motorsports Campus (Outer track) in Tooele, UT, headlined by the Sunchaser 6-Hour Endurance Race on Sunday August 2nd. This is one of the most popular weekends on the NASA Utah calendar — drivers travel from across the region to compete, and the Sunchaser adds a dimension that a standard race weekend can’t match: the race starts in the heat of the afternoon and runs into the dark, making it a genuine endurance challenge rather than just a longer sprint. The weekend offers four participation formats:

**High Performance Driving Education (HPDE)** is the entry point for drivers new to track events. Four experience levels are available — HPDE 1 guarantees an in-car instructor; HPDE 2 is for drivers who have been signed off to run on their own; HPDE 3 features more relaxed passing rules and faster traffic; HPDE 4 is for advanced drivers with open passing and requires pre-approval from the group leader. There is no timing or scoring in HPDE 1 through 3. A complete tech inspection form is required before getting on track — forms can be submitted through a local ASE-certified shop or at the NASA tech station, which opens at 7:30am each morning.

**Time Trial** is combined with HPDE 4 and uses open passing. Competitors run against the clock in structured sessions, with grid positions for sessions 2 through 4 set by lap times. A NASA Time Trial license and current car classification are required. Each Time Trial car must display four NASA stickers.

**Sprint Racing** is wheel-to-wheel competition in organized race groups. A NASA Competition Racing license and current medical examination are required.

**Sunchaser 6-Hour Endurance Race** is NASA Utah’s signature event — a team endurance race that begins in daylight and finishes after dark. It’s one of the premier amateur endurance challenges on the West Coast and draws competitors who don’t typically attend standard race weekends.

All participants must pass a tech inspection before driving. Door number cards are available for purchase at Driver Information for $4.50 each — tape numbers are accepted but will not appear in event photography. NASA membership is required — annual memberships and event registration are available at members.drivenasa.com.
