Doubling the prize money for the winners of the Iron Dog resulted in a late surge of entrants, but the size of the field still fell short of a year ago.

Twenty-nine teams of two have signed up for the 2010 Iron Dog in February, a 17 percent drop from the 35 who started last year. The entry deadline was Tuesday.

"We're happy," race director Laura Bedard said. "We'd like to see the number hit 30 at least, but with the economy being what it is, it's tough right now.

"The good news is our recreation class has tripled in size. In fact, there are several (former) pro riders doing rec class this year."

Recreation class riders go from Big Lake to Nome, while professional class racers continue from Nome another 1,000 miles to Fairbanks. Fifteen recreational teams are registered, including one from Iceland.

Earlier this month, the world's longest and toughest snowmachine race announced that the winner's share of the purse would double next year to a record $50,000 in the pro race. Six teams signed up for the 2,000-mile race after the announcement.

The 40 teams that started the 2008 race is the most ever.

Prize money awarded for the 2009 race ranged from $1,000 for 12th place to $17,000 for the runner-up. Iron Dog development director Heidi Griffin said payouts for those spots won't be reduced, although the purse won't be finalized until next year.

After losing its longtime title sponsor, Tesoro, the Iron Dog picked up a $250,000 sponsorship from the National Guard Bureau in Washington, D.C.

Wasilla racers Todd Minnick and Nick Olstad, the 2009 champions who won in a record time, return to defend their title. The Wasilla tandem drove Polaris machines to victory, breaking a four-year stranglehold on the top spot by Arctic Cat. They'll be back in February with Polaris Dragon SP-600 machines.

The three teams that followed them to the finish line on the Chena River also return.

The snakebitten tandem of Tyson Johnson and Tyler Aklestad, who led twice last year on the final stretch from Tanana to Fairbanks only to come up 3 minutes and 18 seconds short, recorded their second runner-up finish in three years.

Marc McKenna of Anchorage and Dusty Van Meter of Soldotna teamed up to finish third, while Eric Quam of Eagle River and Anchorage rookie Bradley Helwig were fourth.

A member of last year's fifth-place team, Tyler Huntington of Fairbanks, said at the finish line last year that he planned to take a break from the Iron Dog after the birth of his second child in two years. But nine months later, Huntington is back with a new partner -- Chris Olds of Eagle River.

One team stands to earn at least $4,000 by just making it to the finish line. Rookies Tammy Barber and Jana Pevan of Willow are the third team of female drivers in race history, and they'll earn $2,000 for reaching Nome and double that if they get to Fairbanks.

Race organizers offered the money in an effort to attract more women to the Iron Dog.

Bedard and Lisa Luther were the first all-female team in 1997. In 2001, Jackie Page and Missy McClurg became the first women to finish.

Financial incentives for women were first offered last year.

"It took a year to draw some interest there," Bedard said. "I expect to see it grow."
