I used the Workout Creator on the Stages Link website, and while it wasn’t difficult, it wasn’t something that I thought was a good use of time for daily workouts and all courses. Laborious, insofar as clicking a mouse and hitting a keyboard can be laborious. The inability to import a workout file left me unimpressed.
Worse yet, when I created a workout set to present intervals for prescribed course distances, as per BBS projections, the L10 zipped through the intervals at a pace that left me completing the whole workout over only half the actual course. It took me about half of the event’s course to figure out what was happening. The laborious exercise of creating the workout had led me to nearly memorize the 9 course intervals, which did serve me well, but the combination of the course builder and L10 was, I found, useless to me for the purpose of on-course interval call-outs. I’m looking for my next device/software solution.
