@cplenge The aerobic fitness schedule at my old unit was very similar to the one you described.  The only difference I believe was that our long slow run was a “Monday fun run” where we could all get out and call our favorite cadence for the Co.   It was remarkable how you could see the new soldiers to the Co and start in B or C ability group and slowly get faster, eventually moving to A group.  We were not a particularly fitness oriented unit, but we did have a well deserved huge ability group A on wednesdays.

By the way this thread/topic mentions a few interesting alternative PT events
