Has anyone figured out how to create a Spartan Virtual Race workout? When creating a custom workout, I want to be able to run a certain distance (distance is not an option for custom), then perform several exercises (squats, lunges, push-ups, etc.), then repeat this several times over the course of 5K, 10K, or 21K. The distance option only seems to be available for a Run workout, but I can't add exercises in a Run workout.
