Ready, set, go: Runners take part in Race Ipa, a 5K organized by KU's School of Law
// JUSTINE PATTON
Sweat trickles down my forehead. My lungs frantically search for air and my breath comes out in uneven pants. My legs are just plain tired.
Then comes the hill. It's really just the slight incline in front of Mrs. E's on campus, but to my fatigued body it looks like a mountain.
"I can't do this."
This thought flashes through my brain. I glance at Andrew. He gives me a reassuring smile and points to something as we turn the corner — the finish line. I will myself to keep running just a little bit further...
When I was a senior in high school, I jogged on the treadmill daily. But as soon as the numbers "2.00" flashed across the screen, that was it — my legs and lungs were spent. You could say that I had flirted with long distance running in the past—but never committed.
In a way, that makes sense. I'm definitely not what anyone would call a "natural-born runner." My legs are short, so my stride is small. And, I have asthma, which makes any kind of cardiovascular activity difficult.
I decided to overcome these limitations this semester to train for Race Ispa, a 5K run the University of Kansas School of Law organized. And trust me, if I can run a 5K, so can you.
READY...
Before I got too far into training, I decided to make sure I was healthy enough to run. I made an appointment with Melissa Caywood, the staff physical therapist at Watkins Memorial Health Center. Caywood told me because college students are unlikely to have any pre-existing cardiac or respiratory issues, most are healthy enough to start a running program. In other words, I was good to go. People who have had running injuries in the past should visit with a physical therapist to find out whether a running program is right for them.
If you've spent most of your college years camped out on the couch instead of logging hard hours at the gym, don't worry. It's not too late for you to get moving.
SET...
Next, I needed to figure out what type of schedule I was going to follow.
I found out that while my exercise routine was definitely going to change, my eating habits didn't have to. Ann Chapman, the registered dietician at Watkins Memorial Health Center, says short races don't require any major changes — only a healthy diet and good hydration.
Beginning runners often benefit from a walk/
jog training program. In this type of program, each session involves walking a little, then jogging a little and repeating. It's easy to get frustrated with this type of program, because it doesn't feel like you're progressing quickly enough. Caywood urged me to be patient and stick with it. "The walking and running combination helps your heart and lungs catch up and condition," she says. "It also helps your soft tissue in your legs to adapt to the forces you're placing on it."
That's what happened to me. I thought because I used to run two miles a day in high school, I would still be able to do it. I ran two miles daily for a week, and by the end of it, a small, painful bruise had developed on my right knee. I asked Caywood about it, and she said that I had likely gotten ahead of myself. I forced myself to rest and ice it for a week — which was a big motivation killer — and then started training with the walk/run program.
Progressing too fast can often result in injury which will only slow down your training.
Not every ache or pain means you've injured yourself. It's normal to feel sore after a workout. There are a few situations, however, when the pain isn't normal. If the pain doesn't lessen after a few days of rest, you may have injured yourself. Likewise, after you warm up, if the
So how fast should you progress? Caywood suggests not increasing more than 10 percent per session. So, if you run for 30 minutes on Monday, on Wednesday you should add 10 percent, or three minutes, to the workout.
soreness doesn't go away during the workout that could indicate a problem.
Time isn't the only aspect of training that affects the intensity of a workout. Three other factors affect intensity: speed, distance and terrain — and individuals should only change one at a time. So, if your program calls for running a longer distance, don't add a hill in there as well.
NOT SO FAST
So, now that you've figured out your training schedule, you're ready to get moving, right?
The cushion shoe: This shoe is the most flexible. It has the highest amount of cushion and allows the most free motion.
The stability shoe: This shoe has a little more stiffness and control. A hard, plastic piece is usually in the arch of the shoe.
The motion-control shoe: This shoe is the stiffest and is not going to allow a lot of motion.
Before you start, you should invest in a good pair of running shoes. Caywood says there are three types of running shoes:
So which shoe is the right one? It depends on an athlete's foot type. For example, floppy.

A shoe for the sale. Find a shoe that fits your foot type, whether it's cushion, stability or control.
flexible feet that roll around a lot while running are best contained by a motion-control shoe. Height and weight often come into play as well. "If a guy who is 6 foot and 210 pounds put on a cushion shoe, he would probably smash it," Caywood says. "It would flatten out after a month or two."
Athletes with an average amount of flexibility and arch (aka most runners) are fine with stability shoes, which was the case for me. I hadn't bought running shoes in a while, so I went to Garry Gribbles Running Sports, 839

cube provided by event organizers in about three minutes, well shy of his best time of 38 seconds. He started doing the Rubik's Cube to calm his nerves when he was competing for the University of Georgia.
The shot put was held in the streets for the first time in the United States in a makeshift ring. Armstrong said the event organizers got everything right. The only nuisance was the telephone line hanging overhead. Armstrong hit the power line on one of his warm-up throws. Despite this, the consensus from the competitors was that Lawrence successfully pulled off the shot put.

Dylan Armstrong launches the shot put high into the air during his third throw at the Kansas Relays' Olympic Men's Shot Put held downtown between Massachusetts and New Hampshire streets on Eighth Street Wednesday night. The Olympic men's shot put featured eight of the world's best shot putters. Armstrong who came into the competition ranked No. 7 in the world won the meet with a throw of 70 1/4".
"It's really unique to see that kind of crowd gathered for just one event in track and field," said Adam Nelson, who placed third. "I think Lawrence did a fantastic job hosting it."
An estimated 2,500 fans really got into the meet when Nelson stepped up to take his first throw. His warm-up routine consists of him urging the crowd into a rhythmic clap, enthusiastically pulling off his shirt, and then hopping down the runway. Nelson did this on all six of his

Neville dominates first day, scores 3,125 points
TRACK & FIELD

Rebecca Neville won three of the four events in the women's heptathlon Wednesday and ended the day in the lead with 3,125 points. Neville won the 100-meter hurdles, the 200-meter dash, and the high jump. She also placed seventh in the shot put.
The weather was colder than anticipated, resulting in slower times in Neville's events. Despite this, Neville said she was pleased with her performances.
"The 100 hurdles, it was a slow time, but it was 40 degrees outside," Neville said. "So to run a 14.35 in 40 degree weather, that's OK."
Despite not doing her best in the hurdles, Neville did set a personal record in the shot put and high jump. She recorded a jump of 5 feet, 5.75 inches in the high jump and a recorded a throw of 31 feet, 5.25 inches in the shot put.
"High jump was awesome today," Neville said. "My third attempt I did a time foul so I couldn't get to do my third attempt, but it's OK."
The 200-meter dash was Neville's last event of the day. She came close to setting her third personal best of the day, finishing with a time of 25.12 seconds. So far, Neville is performing better than she did two weeks ago at the Texas Relays, and more importantly, she is beating a rival.
"A girl that I'm beating right now from Nebraska beat me at Indoor Big 12," Neville said. "That's just showing me how much better I'm getting as we move on in the season."
Neville said she planned to take an ice bath, eat a good meal and get a good night's sleep in preparation for the long jump, javelin throw and 800-meter run set for Thursday. She said she is more than ready for the competition and plans to "kick butt."
"I don't care if it hurts in the 800." Neville said. "It's the last event."

Fool me once, shame on you. Fool me twice, shame on me. Fool me three times, it's because I'm desperately turning a blind eye because, hey, these guys are world-class athletes, and they sure do win a game of basketball games.
When the biggest surprise about a Saturday night arrest is that the point guard wasn't there, that's an issue. A DUI is an issue. A pair of on-campus fights with members of the football team is an issue. Three different battery charges are issues.
It is past time to shine a harsh and unforgiving light on the Kansas basketball program and the real and numerous problems that have been haunting it over the last few years.
Start six years ago, when J.R. Giddens was stabbed in a 2005 fight that witnesses said he instigated. C.J. Giles, who was there at the Giddens stabbing, was arrested for battery in 2006. Sherron Collins was charged with sexual assault, though the charges were dropped when Collins filed a counterclaim for defamation. Then there was Markieff Morris' battery charge. Morningstar's DUI. Fights with the football team, highlighted by Tyshawn Taylor's injury and Facebook posts. Little's battery charge. And now Robinson's.
This isn't to say these are all bad kids. The Morris twins have grown into quality young men since coming to Kansas and Robinson has been through more crap than anyone could be reasonably expected to handle over the last few months. And Self is by no means an evil tyrant. He genuinely cares about the off-court development of his players, and has sent off guys — namely Giles and Giddens — who were a real detriment to the program.
If you want to criticize Kansas coach Bill Self, don't do it over tournament losses. Criticize him for the rap sheet his program has accumulated over his tenure.
But the problem clearly hasn't been addressed in full, and it needs to be. Forget, for a moment, wins and losses, and look at that list. Forget that you're a Jayhawk fan, and tell me if you would root for that team.
