Wow! That is a lot of work – on both days. My athlete (female) was coming off 7-9 mile micro loading before she opened the indoor season. I had her do something like 3×360+ a day prior to the meet. She ran a personal best in the event and came back less than 15 minutes later for a fairly decent 4x200r split.
Regarding your example Jay I would have to consider both the front and back end, particularly what was to follow (300’s throughout the month was my example). For this athlete I knew she could handle the event distance. And since my time with her ended a week prior to the meet I wanted to make sure that she was “protected” and confident. The 360’s were full gaited runs, relaxed and slightly less than maximal race velocity (with 10/15 min recoveries).
My followup recommendation for this athlete (100/200 sprinter) was to shorten that session with split runs and increase the incidence of acceleration and EFE-10/5/10 runs three days out from scheduled comp. And since she seemed better prepared from her initial race I didn’t see the need for anything but relaxed albeit focused tempo the day before.
Unfortunately her handlers fell asleep at the wheel. C’est la vie.
Though getting back to your example Jay, unless there was something I was working on that wasn’t in place or I feared I wouldn’t see in a meet, I probably wouldn’t go too often with your suggested work session. And I certainly would have a relative foundation in place with subsequent possibilities for “plan B’s”! If that athlete was working from a S-L training year program and given the events you mentioned I would opt for progressive step-up splits the day before. Just saying…
