We have many opportunities to “can,” but disciplined athletes know how to “should.” “Can” is the easy path, while “should” trends uphill. Which road will you choose? -Jim

Bonus calibrations from Coach Katie:
You can do all of your mid-run speedwork on downhills so it feels easier; you should incorporate race pace into flat and uphill terrain to better prepare for hilly races.
You can ignore a niggle during your workout and tell yourself that you’ll deal with it when the workout is done; you should back off when your body is telling you something is wrong.
