This.but this is a ride that is governed by your head not your body....
I'd also add and it's perhaps a personal observation ... finishing is the goal and all that matters. Don't let your 'plans' and 'schedule' detract from that. You may not reach somewhere at the time you'd planned, a section may take longer than you thought and the conditions worse than you imagined but it doesn't matter. Don't let a minor defeat trick you into losing the war.
