This isn't your typical workout in an indoor gym. More than 100 people gathered for an “Indoor Tri" at Lifetime Fitness in Omaha on Sunday.
It's an indoor triathlon meant to get your blood pumping and your heart racing.
This is Trisha Glenn's first time participating.
“It feels good, I mean I've never done anything like this before so it definitely feels like a good accomplishment.”
The hour and twenty minute workout starts with a ten minute swim and then 20 minutes of cycling.
Groups have a couple minutes between each event to get to the next one and then it's on to the treadmill.
The class is challenging young and old. 10-year-old Madock Bikus says now he wants to do more triathlons.
“I want to keep doing them so I can get healthier and stronger and faster.”
Race director Sandy Bikus says triathlons are becoming the fastest growing sport in the country.
“The energy of triathlon is absolutely addicting,” says Bikus.
“It's very appealing because of the variety, its very low burnout because you have the variety of the three different sports.”
It’s because of the variety, triathlons tend to have a lower injury rate than other sports.
They allow people to set individual goals, while being inspired by those working to accomplish their own.
“You dial up the pace and the tempo at your current fitness level and you answer to yourself,” says Bikus.
Bailey Rolfsmeier came from Lincoln with friends to participate and says she's hooked.
“I'm tired, but it was an awesome experience and it was very rewarding to come out and do this. In the beginning I wasn't so sure about it but now, its amazing.”
The event was so popular that Lifetime Fitness scheduled another "Indoor Tri" in March.
The cost is $25 for members and $30 for non-members.
