In June 2021, I failed to reach my goal of completing nine hours of running or rowing at moderate intensity in the final four days of the month. Nevertheless, I learned several things from the attempt, which will probably improve my exercise performance.
running
My last three pairs of Brooks Adrenaline GTS (versions 16, 18, and 19) and the current pair (version 21).
Rowing for 60 minutes, followed by a 5-km run, yielded better results than running or rowing for 85 consecutive minutes.
