Nick Diaz training camp for UFC 137 includes 30th annual Donner Lake Triathlon

Don't be tired, homie.

Former Strikeforce Welterweight Champion Nick Diaz, who surrendered his title in order to defect to the UFC and challenge Georges St. Pierre on Oct. 29, has already got his feet wet, literally, in getting his UFC 137 training camp off the ground.

Diaz completed the 30th annual Donner Lake Triathlon last Sunday (July 17, 2011), placing 36th overall with a time of 2 hours, 46 minutes and 20 seconds. Coming in at 36 might not sound that impressive -- until you consider it was good enough to beat 256 other contestants.

North Lake Tahoe Bonanza has more:

"Well, I like Tahoe, and this is the best road race in Tahoe," said Diaz, 27, explaining why he's made the trip from his Stockton home "six or seven times" to compete in the Donner Lake Triathlon.

"It keeps me in great shape. I'll be in great shape when I start training camp," said Diaz, the fourth-ranked welterweight in the world by MMA Weekly. "A lot of mixed martial arts guys who train only at one sport will fall short at some point in a fight, whereas an all-around good athlete can go further, in my opinion."

No one looked to argue with him as Diaz, still a bit winded after swimming 0.9 miles, cycling 24.8 miles up Old Highway 40 and back and running 6 1/2 miles around Donner Lake, proceeded to take a photo with a fellow racer's two children.

Diaz is no stranger to triathlons, telling me in 2007 they keep him in shape while he's in between fights.

But he'll need more than good cardio to overcome St. Pierre.

This will be the first time Diaz has fought under the UFC banner since a Nov. 2006 win over Gleison Tibau. He hasn't fought in Las Vegas since Feb. 2007, a submission win over Takanori Gomi (later overturned to a no contest thanks to a failed drug test) under the Pride banner.

St. Pierre, fresh off a close unanimous decision win over Jakes Shields at UFC 129 last April, heads back to "Sin City" for the first time since his five-round beatdown of Thiago Alves at UFC 100 back in July 2009.
