From the base of Table Mountain and Colorado's spectacular foothills, All-Out Multicourse presents our 12th annual Kooky-Spooky from Jefferson County's NAAC Stadium… easily accessible from several nearby highways. Along with its Endless Series sidekick in March, Spring Fever, these 5K, 10K & Half Marathon courses will hug the shores of Arvada's Blunn Reservoir via the Ralston Creek Trail and will challenge the beginner and veteran athlete alike!

Features you can look forward to

• An after-party at Colorado Tap House with fun for adults and kids including live music, games, and a FREE beer with tag from your bib
• A costume contest with six categories plus an overall winner that wins a free All-Out race!
• FREE medal engraving, so you can add whatever you'd like to the back of your medal
• SWAG of super-awesome beanie cap, distance sticker, and finisher medal for all finishers
• Warm, in-building restrooms at the venue and multiple toilets on course
• A post-race meal including warm cider (depending on temperature), delicious breakfast burrito, fruit, and of course Halloween candy!
• Frequent aid stations with energy gels (10K & half marathon only), water, and gatorade
