CrossFit Open 2015

The CrossFit Games stand alone as the ultimate test of fitness. No test, regardless of its lofty claims, can grant legitimate title to the best without first providing access to all. 
The 2015 Reebok CrossFit Games season begins with the online Open. Anyone can sign up to compete in five workouts over five weeks and post their scores online. Last year, the Open reached more than 209,000 athletes from around the world.
You can either perform the Open workout at a participating CrossFit affiliate where you will be judged in person, or you can film your full performance and upload it to YouTube or another video-sharing site. The video will be displayed alongside your score so other CrossFit athletes can be your judge.

You are free to make as many attempts at the Open workout as you please. Your only limit is time. You have four days—96 hours—to complete the week's workout and submit your best score to the Games site. The week's workout is released each Thursday at 5 p.m. PT, and scores are due the following Monday at 5 p.m. PT.

The 2015 Open begins on Thursday, Feb. 26. That evening, tune into the live Open announcement show streamed to Games.CrossFit.com. Director of the Games Dave Castro will announce Open Workout 15.1 and moments later top Games athletes will complete that workout going head to head.
Athletes will submit their scores throughout the weekend. The hard deadline for score submissions is 5 p.m. PT on Monday, March 2. Don't be late!
