I did my first ever obstacle run today at Camp Rhino With some Co-workers. They walk you through all of the obstacles first & show you how to complete them safely & efficiently if you go early for the 9:30 AM Beginner crash course.  Then, at 11 we ran the Saturday Practice Course.  Tough, but doable if you already have some strength & Cardio.  l really enjoyed the instructor and doing the course was super fun.  It took me 44 minutes... now I want to go back & beet my record!
