MURRAY It's part road bike, part mountain bike and part steeplechase.
And it's exploding in popularity.
It's cyclocross, and it is becoming one of the fastest-growing sports in the bicycle world.
"I love it," said Jeff Clawson, a local cycling promoter and club organizer with Canyon Bicycles in Draper. "It's a sport where a beginner right up to a pro can come and race and have a great time. They can bring the family and they can see you on every lap."
This weekend at the Weber County Fairgrounds, the Utah Cyclocross Series will hold its state championship races. And, if recent competitions are any indicator, there will be upwards of 300 participants in the various classifications.
Last weekend, for example, there were more than 300 entrants in the weekly races at Wheeler Farm on Saturday and a few dozen more on Sunday at a race in West Valley City.
And while those coming to race are falling in love with the sport, many have little idea it exists or why it is so popular.
The sport has been around for more than a century with the first known race held in Europe in 1902. It is said to have developed as a form of competition for road cyclists to participate in during the fall and winter months when weather conditions prevented racing and training on slick roads.
Embracing the conditions, cyclists raced their bikes across fields, hillsides, through groves of trees and across fences for fun and for training purposes. Slowly, the sport took off and is now hugely popular in Europe while also gaining considerable traction in the U.S.
In fact, Lance Armstrong helped kick off his return to competitive cycling by lining up for a cyclocross race in Las Vegas shortly after he announced his comeback.
"It's a great spectating sport," Theresa Carr, a frequent participant in the races, said. "People can get around the whole course and see what's going on. I think it has more of a grass roots feel than even mountain biking. There's just more of a community feel to it."
The bikes used often have a road bike frame, but usually come with thick, studded tires ideal for off-road conditions. Even the components are usually scaled down to make the bikes more simple to ride and easier to handle.
Each cyclocross race is different. Depending on the terrain and the event promoter, the course is built each week with unique twists, turns, climbs and obstacles. And if the weather throws some ice or rain at the competitors, they're usually a little happier.
Courses typically require riders to cover multiple laps, and in most cases the riders must dismount their bicycles several times to climb steep hills, jump logs or hurdles or cross streambeds.
The less-formal nature of the races creates a casual yet highly-competitive event.
"This is what people get off on," Clawson said. "It's all up close. You can see everything out here."
And, cowbells in hand, families and friends are flocking to the events.
"It's extremely addicting even as painful as it is," Carr said. "You ride so hard, but it's so challenging and demanding. You really get sucked into it." With the exception of the top national or world events, most races last an hour or less. The sport is governed by cycling's highest body, the UCI, and has world cup and championship races. Locally, the sport is dominated by Bart Gillespie.
The pro-level cyclist is nearly always on the podium at local races and often the real race is for second. That hasn't stopped many from coming out to get in on the action. Cyclists such as Eric Rasmussen, Reed Wycoff and Ali Goulet are usually in the mix for wins.
"It's something that's successful because you can do it with just a modest investment," Clawson said. "Look at all this. There are young kids racing around on their bikes. They're having a blast and it's really a family thing. With the races set up the way they are, dad can race, mom can race, the kids can race and it's all right here."
In Utah, the location of races varies from Wheeler Farm to Fort Buenaventura in Ogden and the Corner Canyon trails in Draper.
In addition to the top-level races, there are categories for beginners, women, juniors and Masters 55 and older.
And, unlike some of the summer road or mountain biking events, racing will not take all day or require massive amounts of endurance."It's because the race durations are short. You can do it and still have plenty of time for your day," Carr said. "From what I can see, it's family oriented. There is nothing better than watching those little kids out there."
