Sprints coach, The 3rd athlete I coached that won a national title moved to the same coach that the last athlete I coached to win a national title did, 20 years apart. Relevance not much.
A question was asked and I simply answered. By morning I mean finishing before 7.00am, the reason for a split session with a total daily time frame of 1.5 hours was simply because the athletes had to work. I presume you must have tried the split sessions to come to the conclusion that “” the effect will be the same on the speed in the evening". I beg to differ. What I found was the resting am heart rate was lower and more consistant. Cheers.
