Turns out the Chicago Blackhawks are beatable. It just took 25 games to prove it.

The Blackhawks found ways to win almost every night to start this shortened season -- or at least earn a point. They rallied, they dominated and they scored late goals to salvage something in the first 24 games.

The magic ran out almost a year to the date of their last regulation loss.

Matt Duchene and John Mitchell scored 33 seconds apart in Colorado's four-goal second period and the Avalanche ended Chicago's historic run with a 6-2 win on Friday night.

"We're proud of it but it'll be nice to move on now," defenseman Duncan Keith said. "It's hockey, we've lost games before in our lives. It's not like we're going to sit here and cry."

But it has been a while since the Blackhawks were pointless.

Chicago started the season with at least a point in 24 straight games, an NHL record. The Blackhawks earned a point 30 straight games over two seasons, bested only by the 1979-80 Philadelphia Flyers, who did it in 35 straight games.

Now, those marks are in the books after last-place Colorado did what no other NHL team could this year. The Blackhawks' last regular-season regulation loss was 6-1 to Nashville on March 25, 2012.

As the streak grew, so did the attention, and teams approached the Blackhawks with incentive.

"It's gained a lot of momentum over the last little while and our opponents, they treated it like it was a very important game," Chicago coach Joel Quenneville said.

For the Avalanche, every game is now important. They had lost six of their last seven entering Friday and were six points behind St. Louis for the eighth and final playoff spot in the Western Conference. Getting two points was important, and doing it against Chicago was an added bonus.

"It's special," Duchene said. "What a run by them. I don't think they're going to slow down because of this but it's pretty special. We're pretty happy."

Duchene had a lot to do with the win. He added three assists and P.A. Parenteau and Paul Stastny had a goal and two assists each. Ryan O'Reilly and Jamie McGinn also scored for Colorado, which avenged a 3-2 overtime loss in Chicago on Wednesday.

"To be the team to stop them, we had a chance last time and didn't do it," Stastny said. "We wanted to stop their streak and get one going for us."

Jonathan Toews and Bryan Bickell scored for the Blackhawks, who also had their franchise-record 11-game winning streak snapped.

Early, it looked like they would make it 25 straight when Marian Hossa, back after missing Wednesday's game with an upper-body injury, fed Toews for his 11th goal of the season 5:44 into the game.

Colorado tied it 11 minutes later when Stastny scored his seventh of the season to start the Avalanche onslaught. Duchene gave Colorado the lead with his ninth goal 4:16 into the second, Mitchell beat Corey Crawford at 4:49 and the rout was on.

"We gave them too many open shots from the slot and made it too difficult on our goaltenders to make those stops," Toews said. "We had chances to stay close but didn't play smart enough in our own zone."

O'Reilly got his first goal of the year four seconds into a power play midway through the second and McGinn ended the rally with his fourth goal at 13:58.

Crawford allowed five goals on 19 shots before being replaced by Ray Emery to start the third.
