I’ve done it both ways and to be early and get the rowing done first thing in the morning is always better. Coffee even tastes better afterwards.
Today’s session was Pete Plan designated as steady distance / recovery. Not much to recover from yesterday though. The distance chosen today was 11K. DF 120. Average rating 24. HR took a little while to climb up into zone 1 which is the lowest aerobic zone for me with boundaries of 133-142 but it got up into that area after about 8K and stayed there until the finish.
Happy trails to you.
