Round 2, not sure how to meet the workouts.

Hey guys, I first did 75 hard last January, and to cover one of my 45 minute workouts I switched from public transport to walking home from work - about 50 minutes. (I also started walking in the morning but that immediately followed my gym session so just counted as extra steps/movement). I’m thinking of restarting on Tuesday BUT one habit I kept up from last time was walking to and from work on my office days. I remember the 2x workouts need to be different right? As in on my office days I will need to still find time for that extra outdoor workout as my existing walk to and from work won’t count?
