Same interval formats at every Homestretch, so you can drop in anywhere and know the clock.
The 5:30 AM Engine has a Brookside quirk: Renee plays the same playlist all month and takes requests for the next one.

Engine questions
How hard is Engine?
As hard as you make it. The coach gives you a target effort, not a target number, so a beginner and a marathoner can share a row.
Is there running?
Not indoors. On nice Thursdays the 6:30 PM class may finish with an optional easy jog on the neighborhood trail.
