Johnston said he visits the Preston Center about two or three times a week and uses the Bill Powell Natatorium to swim frequently.
"I'm 72 years old, were it not for the Preston Center, I would probably not be in as good of shape as I think that I am," Johnston said laughing.
However, Johnston's dedication to the Preston Center extends from the active lifestyle he said he has held in the past. He played tennis all throughout high school and college and then started running. He ran the New York City marathon twice and then began competing in triathlons soon after that. He said he once ran two marathons within two weeks of each other – one in New York City and the other in Louisville.
"And then when the body starts to break down a little bit more, pilates and swimming is an excellent choice," Johnston said.
Johnston said a typical swim workout is spent working on the backstroke.
"A typical swim workout for me is not quite as vigorous as Coach Powell's but I do try to swim 72 lengths," Johnston said.
Johnston competes in meets on the state and national level.
"And that sounds like 'Oh, you must be a good swimmer.' Not really. There's just not that many 72 year olds that can still swim a 200-yard backstroke," he said.
Johnston said he hopes the Preston Center will continue to develop as the university continues to develop, as well. He said he thinks the students are more interested in physical fitness than they were 20 or 30 year ago.
"Students love when they come to a college campus to look at the recreational facilities and the Preston Center has really gone above and beyond what has taken place at a lot of the other universities here in the country," Johnston said.
The Preston Center is a place where the student body develops. Johnston said the Preston Center is and will remain a special place to him because it allows him to get to know the students that are working in the facility while also maintaining an active lifestyle.
