Yes, I've registered for the Open. I'm looking forward to this year as I feel some pressure has been taken off. The reason for this? We can scale workouts this year. Of course, that means that it will affect our scores but we won't be taken off the leaderboard - from what I understand we will be given a score of less anyone doing RXD. I'm happy with that. It will be interesting to see what the workouts will be; does it mean more complex movements? Quite possible, but again I'm okay with that.
Now to get those darn muscles in my back to play nice so I can be in tip-top shape for the first workout.
