Two people, a man and a woman, are running outdoors on a sunny day. They are dressed in athletic wear with a mountainous landscape in the background. The sun is low, creating long shadows on the pavement. Greenery and city buildings are visible in the distance.

Here are five adages to live by as you train:

Proceed like a beginner

Especially in the beginning, build to speed and distance like you are just starting. This will stave off injury and frustration.

Adjust goals often

Really pay attention to your effort. After building your base back, revise your goals to be faster or slower depending on how you feel. Keep adjusting as necessary.

Evolve

What worked before may not work now. A 22 miler might give you the confidence you need on race day. Or you might need an extra rest day. Know thyself.

Tune up

Use shorter races to give yourself a gauge of fitness throughout the cycle. These can be great indicators of what to expect for your goal race.

Recover smart

If you fear the slow process of another comeback, recover with a reverse taper. Take up to a week off with complete rest if needed depending on race effort. Ease back into walking or easy running for another week or two before adding on miles. Carissa Liebowitz has run the Boston Marathon as well as dozens of marathons and half marathons.
