Great Oak's Jade Miller wins the D1 300 Meter Hurdles during the 2013 CIF SS Track & Field Divisional Finals Saturday in Walnut, CA. May 18, 2013.

Temecula Great Oak graduate Jade Miller is preparing to compete in the USA Track & Field Junior Olympics at the end of July and the Pan American Junior Championships in Medellin, Colombia at the end of August.

Miller won the CIF-State title in the 300 hurdles, running a national best 41.02 seconds, and went undefeated in that event during the season. Her graduation present, essentially, was adding another 100 meters to her hurdles race, the collegiate and international distance of 400 meters.

“I like them,” she wrote in a Twitter exchange. “I know I will never run the 300s again, so I am trying to put on my big-girl pants and get used to my new race.”

She placed second in her first shot at the 400s at the USATF Junior Nationals last month in Des Moines, Iowa. She has not competed since and won’t until the July 22-28 Junior Olympics at North Carolina A&T University in Greensboro, N.C.

Asked what she has been doing to prepare, she quickly wrote back: “Whatever my coach tells me to do hahahaha.

“We are just doing maintenance. I ran the 400 during the season a bit and the 550 indoor. So we know I have the endurance. It is just about keeping healthy.”

The trip to Colombia will force Miller to miss her college orientation at Harvard. She said she will be able to arrive at the Cambridge, Mass., campus by “move-in day.”
