Life is more funwhen you feel fit
ZOO 305 is a weekend boot camp in Moslavina, Croatia designed for Spartan and obstacle-course athletes who want real-world strength, efficient pacing, and terrain confidence. We train with awkward loads (logs, sandbags, buckets), rope skills, trail intervals, and smart recovery—everything you’ll meet on course, minus the gimmicks.
02
Scalable Coachingon Real Terrain
Each session is scalable, coached, and built around technique under fatigue, so beginners gain skill and experienced racers sharpen speed and economy. If you’re aiming for your first Spartan or trying to PR your next Super, Beast, or Ultra-style effort, ZOO 305 gives you a focused environment to do the work—on the ground, in the elements.

Our mission
Help athletes build useful strength and sustainable speed for obstacle races—through simple tools, real terrain, and coaching that respects your body and your goals.
Build Race PowerTrain smarter. Finish harder.
We’ll raise work capacity through EMOMs/AMRAPs and time-under-tension sets, dial race craft (pacing, transitions, fueling, gear, wet-weather plans), and reinforce a resilient mindset—calm under fatigue, coordinated as a team, precise on course.
