American Elites' New Year's Resolutions

To run a 400 in 53 seconds in practice.

Running resolution: Other Hearst Subscriptions.

How I'll do it: Sometimes it's the fundamentals that get lost in the search for the next big jump in fitness. I will set aside 15 extra minutes at the end of every run to go through a routine of simple stretches. Even when it's cold outside or I am super tired, I'll run through the major muscle groups to ensure a healthy and injury-free year of training and racing. The consistent stretching will also promote range of motion and support every other aspect of my training.

Non-running resolution: To call my grandparents once a month. They are so supportive of my life and career and I'm terrible about keeping in touch with them between family holidays!

Running resolution: To have an injury-free year and be fit for my wedding [on September 20 to Air Force Academy grad and Rhodes Scholar Brittany Morreale].

How I'll do it: Use a stretching rope to stretch every day after running. Although I dislike the cold, I will use the ice bath two times every week to speed up recovery. And I will sleep at least eight hours per day to give my body the time for recovery.

Non-running resolution: Shoes & Gear.

How I'll do it: Wear a heart rate monitor on the day after a hard workout and make sure my heart rate stays under 145, even if I practically have to crawl to do it.

How I'll do it: Make the final 25% of my intense workout the primary focus and finish those intervals or runs strong.

To do what is in my control to stay injury-free all year long.

Running resolution: I want to be faster over the last lap of my races.

How I'll do it: Do some fast strides once or twice a week after my 10-mile morning runs on non-workout days. I will focus on form and having a racing mentality during my speed sessions to try to simulate the last lap of a race.

Non-running resolution: I want to do a Rosetta Stone course to relearn Spanish while we're in Europe over the summer and I have nothing else to do besides run, eat and sleep.

Running resolution: She Runs to Reclaim Her Identity After Assault.

How I'll do it: Put together several weeks of consistent and healthy training. Focus on the little things that keep me healthy: core work, pre-run drills, post-run strengthening, yoga, and strides. Be patient -- not every workout or race will be a home run, but it will be important to the bigger picture. Don't overextend trying to do too much too soon.

Non-running resolution: Drink less beer.

How I'll do it: This past year, incorporating more beet juice, spinach, and omega sources (salmon, avocado, fish oil tabs) into my diet was a major focus, as well as eliminating soda from my diet, except on a special occasion. This year, I will focus on gradually filtering some (very likable) processed foods out of my diet and replace them with healthier options.

Non-running resolution: To be a good friend to my friends who have young kids. I hope I can be a strong support system to them.
