Awesome project, Stephen! A structure like you suggest is probably how I'd approach something like this. Each "tier" of your training would be a separate project, with a repeating action inside to track the training sessions.

An alternative, if you want to plan the whole thing out start-to-finish would be a sequential project with each run as a non-repeating action, I suppose. One possible advantage there would be that showing completed actions would show you exactly where you were in the process towards the final run. With the repeating setup, you could see what you'd done, but a the remaining steps would only be completed as needed.

Either way could work, though - it's really a YMMV situation. Literally, in this case, which is kinda funny. :-)
