SNOWBASIN -- The heavy terrain took its annual toll of riders Saturday at the Mt. Ogden 100K Mountain Bike Race.
For the fourth annual event, 365 riders registered, the most ever. But only 318 finished.
The 47 DNFs, for Did Not Finish, was about par for the course, so to speak, said officials from Snowbasin, sponsor and host of the race.
"We've had champion riders say our course is one of the toughest in the country, and as a result, one of the most rewarding," said Steve Andrus, chief race organizer and Snowbasin sales director.
The DNFs were mostly technical issues with equipment, or simply flat tires, as opposed to occasional injuries. All the injuries were minor, organizers said, competitors able to leave the course unassisted.
Riders came from 25 states as well as Canada, Switzerland, and Austria.
The races have always been plural with a 50-kilometer ride as well as the 100K, about 62 miles. The latter comes with a hefty purse: $1,000 goes to first-place for both the men's and women's divisions, with matching second-place prizes of $600. It's $450 for third, on down to $50 for 10th-place finishers.
The 100K event drew some of the country's champion mountain bikers, said Andrus, whose nickname is "Yeti" because of the impression he makes at 6 feet 6 inches tall when he skis.
Some of the champions, he said, were from that rare group of maybe a few hundred in the country with enough sponsors and prize money to make a living at mountain biking.
It also attracted 13-year-old Drew Palmer-Leger from Park City.
This year marked the first time for a 25K event, about 15 miles, added by Snowbasin for amateurs and youngsters. Palmer-Leger was the overall winner in the youth division in the 25K, his first, with a time of one hour and 35 minutes.
"I've been racing mountain bikes since I was 8," he said by way of explanation. His parents and 10-year-old sister also raced Saturday. He proudly noted sister Sydney is the current national champion in the 10-and-under division of mountain bike racers.
The courses for the three race categories meandered through the mountains around the ski resort and featured 11,000 feet in "total elevation," meaning the various rising and falling of the bike paths amount to an 11,000-foot ascent. And the courses are "90 percent single-track," officials explained, meaning few developed roadways, such as maintenance roads or side roads.
Racers all crossed the same finish line in front of Snowbasin's main lodge, the mat at the finish line wired to timing technology to beep a computer chip in each competitor's number sash, worn across the chest. The cyclists then match their number to the scorekeeper's laptop to get their official time.
"This stuff is tech," said Jason Dyer excitedly, another Snowbasin staffer and race organizer, as he watched the beeping riders cross the finish line.
With some of the bigger races, Dyer said, like Tour of Utah, the chip in the number tag can give the rider a readout of their time in progress during the race, allowing them to adjust their pace as needed.
"We're not as big as Tour of Utah yet, but we will be," he said.
