I had a look at the wkt file and it is out of date. The workouts are scheduled in 2010 / 2011 so loading into GTC won't schedule the workouts.
The RW plan asks for the race date as a variable and generates the dates for workouts accordingly.
Two options. Hack the wkt file to change every date, or ask RW to update the VLM ready file so that it can be used for 2013.
