You can make a lot of progress if you do this one thing:
Keep making slow and steady progress.
In yesterday’s 7-mile run, edit out the first slow warmup mile, and the last two slower cool down miles.
What’s in the middle is the real story. Four progressively faster miles.
And it is the last mile in the official workout (excluding warmup/cool down) that the real story comes alive.
Dropping a 6:23 on the final mile.
A seriously delightful surprise.
