JUST DO IT It’s springtime. Quit neglecting your New Year’s resolutions and get up off the couch. If it has been a while since you’ve gone out for a run (or taken the stairs), the following events should be a source of motivation to get your blood pumping, whether you are participating or merely observing.

March 2: The St. Patty’s Day Rattlesnake Challenge is a three-pronged race through Huntsville State Park that includes kayaking, mountain biking, and running or walking. This race, which covers 20 to 25 miles and usually lasts between four and six hours, is not for the weak.

March 9 and 10: The Austin Rowing Club hosts the Heart of Texas Regatta. About eight hundred competitors will be at Town Lake for the one-thousand-meter course, which takes on average three and a half minutes to complete. Note: The best place to watch the action is from the Congress Avenue Bridge.

March 17: Individuals or teams can test their endurance and strength during the twenty-fifth annual Transmountain Challenge, a twenty-kilometer run (or walk) on a course in El Paso that reaches an elevation of 5,250 feet.
