Alien Dash 5K: The Fast Slice
Race Day Weather
Warm start, warming through the race
A warm 71°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temperatures rising to 86°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 67% is worth noting for effort level, especially in later miles.

Race Info
The 5K is a single lap of a flat beach path in Long Beach, starting and finishing at 5400 E Ocean Blvd. The course turns at a marked flag near the 1.55-mile point and comes back along the shoreline to the start line. Its level paved surface makes it a fast, beginner-friendly distance that also welcomes walkers, strollers and leashed dogs.
